Qualitative validation consists in showing that a model is able to mimic available observed data. In population level biological models, the available data frequently represent a group status, such as pool testing, rather than the individual statuses. They are aggregated. Our objective was to explore an approach for qualitative validation of a model with aggregated data and to apply it to validate a stochastic model simulating the bovine viral-diarrhoea virus (BVDV) spread within a dairy cattle herd. (...) Repeated measures of the level of BVDV-specific antibodies in the bulk-tank milk (total milk production of a herd) were used to summarise the BVDV herd status. First, a domain of validation was defined to ensure a comparison restricted to dynamics of pathogen spread well identified among observed aggregated data (new herd infection with a wide BVDV spread). For simulations, scenarios were defined and simulation outputs at the individual animal level were aggregated at the herd level using an aggregation function. Comparison was done only for observed data and simulated aggregated outputs that were in the domain of validation. The validity of our BVDV model was not rejected. Drawbacks and ways of improvement of the approach are discussed. (shrink)

Using an interpreter in qualitative interviews: does it threaten validity?There is an extensive literature on the problem of translating scales for use across cultures, but very little is published on the problems of conducting qualitative interviews in another language with assistance of an interpreter. The aim of this paper is to describe and discuss threats to validity that arise when conducting qualitative interviews using an interpreter. Ten female student nurses in two cities in Lithuania were interviewed about (...) how they perceived their educational program. All interviews were conducted in English with an interpreter. When using an interpreter to conduct interviews, potential threats to validity arise at various points in the interview process. A threat arises when the researcher, whose first language is Swedish, addresses a question in English to the interpreter, another during the translation by the interpreter from English to Lithuanian, and again when the interpreter translates the interviewee’s Lithuanian responses to English. In the last situation, the researcher may not know whether the interpreter has summarized and/or modified the responses. To mitigate these problems, the interpreter should not only have the required linguistic abilities, but also be trained in the research field. The researcher has to be aware of these threats to validity and make efforts to meet and limit their effects. (shrink)

It seems that many qualitative researchers have still not contextualized the role of validity in qualitative analysis.This article enumerates three factors that must be taken into account: The philosophy of science within which one works, the discipline to which one belongs, and the subfield of specialization that one pursues. Most researchers have encountered the question of validity within the context of empirical science, but validity does not have the same role within a phenomenological philosophy of science. Within the (...) discipline of psychology, certain subfields ignore the validity issue for good reasons and other subfields specialize in developing strategies for validity. This article analyzes the reasons that the specialty of "test construction" focuses so strongly on validity issues and concludes that phenomenological qualitative research is not at all similar to the situation one finds in test construction. Rather, phenomenological qualitative research is closer to experimental situations and so the validity issue is not as pressing as is often supposed. The article ends with two different Husserlian perspectives on a theory of knowledge. (shrink)

Arrhenius and Rabinowicz have argued that Millian qualitative superiorities are possible without assuming that any pleasure, or type of pleasure, is infinitely superior to another. But AR's analysis is fatally flawed in the context of ethical hedonism, where the assumption in question is necessary and sufficient for Millian qualitative superiorities. Marginalist analysis of the sort pressed by AR continues to have a valid role to play within any plausible version of hedonism, provided the fundamental incoherence that infects AR's (...) use of such analysis is removed. But what AR call ‘Millian superiorities’ are never genuine qualitative superiorities in Mill's sense. Mill scholars need to appreciate this point and recognize that the interpretation of qualitative superiorities as infinite superiorities is the only interpretation which is compatible with the text of Mill's Utilitarianism. The continuing failure to appreciate the possibility of infinite superiorities has precluded any adequate understanding of the extraordinary structure of Mill's pluralistic hedonistic utilitarianism.

Qualitative research has tended to evoke rather stereotyped objections from the mainstream of social science. Ten standardized responses to the stimulus "qualitative research interview" are discussed: it is not scientific, not objective, not trustworthy, nor reliable, not intersubjective, not a formalized method, not hypothesis testing, not quantitative, not generalizable, and not valid. With the objections to qualitative interviews highly predictable, they may be taken into account when designing, reporting, and defending an interview study. As a help for (...) new qualitative researchers, some of the issues, concepts, and arguments involved are outlined, and the relevancy of the standard objections is discussed. Alternative conceptions of qualitative research, coming from phenomenological and hermeneutical traditions, are suggested. The qualitative interview based on conversation and interaction here appears as a privileged access to a linguistically constituted social world. (shrink)

Background: Emergency exception to informed consent regulation was introduced to provide a venue to perform research on subjects in emergency situations before obtaining informed consent. For a study to proceed, institutional review boards need to determine if the regulations have been met.Aim: To determine IRB members’ experience reviewing research protocols using emergency exception to informed consent.Methods: This qualitative research used semistructured telephone interviews of 10 selected IRB members from around the US in the fall of 2003. IRB members were (...) chosen as little is known about their views of exception to consent, and part of their mandate is the protection of human subjects in research. Interview questions focused on the length of review process, ethical and legal considerations, training provided to IRB members on the regulations, and experience using community consultation and notification. Content analysis was performed on the transcripts of interviews. To ensure validity, data analysis was performed by individuals with varying backgrounds: three emergency physicians, an IRB member and a layperson.Results: Respondents noted that: emergency exception to informed consent studies require lengthy review; community consultation and notification regulations are vague and hard to implement; current regulations, if applied correctly, protect human subjects; legal counsel is an important aspect of reviewing exception to informed-consent protocols; and IRB members have had little or no formal training in these regulations, but are able to access materials needed to review such protocols.Conclusions: This preliminary study suggests that IRB members find emergency exception to informed consent studies take longer to review than other protocols, and that community consultation and community notification are the most difficult aspect of the regulations with which to comply but that they adequately protect human subjects.

In psychotherapy research, treatment efficacy is commonly studied by means of self-report questionnaires to gain quantitative data on symptom development. The data serve as input for statistical analyses up to the level of evidence-based treatment. We analyzed how a patient in a psychotherapy study experienced the translation of her story into quantitative data by combining a phenomenological qualitative analysis of her therapeutic narrative and a visual analysis of her extensively annotated paper-andpencil questionnaires. Our findings provide a practical empirical illustration (...) of the nature and impact of known validity issues. Beyond, we found the act of questionnaire administration affected the primary complaint such that it became performative toward the symptoms under study. We discuss the epistemic consequences for the validity of data, and we argue that valid data collection requires qualitative scrutiny of meaning within data and a concept of validity that allows for consideration of performativity of data collection.

Mother-to-child transmission of the Human Immunodeficiency –Virus is a serious public health problem, contributing up to 90% of childhood HIV infections. In Tanzania, the prevention-of-mother-to-child-transmission feature of the HIV programme was rolled out in 2000. The components of PMTCT include counselling and HIV testing directed at antenatal clinic attendees. It is through the process of Provider Initiated Counseling and Testing that counselling is offered participant confidentiality and voluntariness are upheld and valid consent obtained. The objective of the study was to (...) explore antenatal clinic attendees’ experiences of the concept of voluntariness vis- a- vis the implementation of prior counseling and subsequent testing for HIV under the PITC as part of their antenatal care. In-depth interviews were conducted with17 antenatal clinic attendees and 6 nursing officers working at the Muhimbili National Hospital antenatal clinic. The study data were analyzed using qualitative content analysis. Antenatal clinic attendees’ accounts suggested that counselling and testing for HIV during pregnancy was voluntary, and that knowledge of their HIV status led them to access appropriate treatment for both mother and her newborn baby. They reported feeling no pressure from nursing officers, and gave verbal consent to undergo the HIV test. However, some antenatal clinic attendees reported pressure from their partners to test for HIV. Healthcare providers were thus faced with a dilemma of disclosure/ nondisclosure when dealing with discordant couples. Antenatal clinic attendees at MNH undertook the PITC for HIV voluntarily. This was enhanced by their prior knowledge of HIV, the need to prevent mother- to- child transmission of HIV, and the effectiveness of the voluntary policy implemented by nursing officers. (shrink)

We respond to several important and valid concerns about our study (“The Prevalence of Folk Dualism in Early China,”Cognitive Science 35: 997–1007) by Klein and Klein, defending our interpretation of our data. We also argue that, despite the undeniable challenges involved in qualitatively coding texts from ancient cultures, the standard tools used throughout the cognitive sciences—large quantities of data, coders as blind to the hypothesis as possible, intercoder reliability measures, and statistical analysis—allow the noise of randomly distributed interpretative differences to (...) be distinguished from the signal of genuine historical patterns.

The paper discuss the application of qualitative and quantitative techniques in political studies. It describes the classical proposal of Johan Galtung, known as trilateral science, which invites to the permanent contrast to confirm, validate and accept facts and ideas; then it explores Grounded Theory as a mechanism to achieve and explore data in order to identify a possible dialogue with experimental methodology. Finally, it shows social capital as a case study to demonstrate the relevance of multi-methodological applications.

The aim of this research was to gain insight into the experiences and perspectives of individual members of a Medical Research Ethics Committee regarding their individual roles and possible tensions within and between these roles. We conducted a qualitative interview study among members of a large MREC, supplemented by a focus group meeting. Respondents distinguish five roles: protector, facilitator, educator, advisor and assessor. Central to the role of protector is securing valid informed consent and a proper risk-benefit analysis. The (...) role of facilitator implies that respondents want to think along with and assist researchers in order to help medical science progress. As educators, the respondents want to raise ethical and methodological awareness of researchers. The role of advisor implies that respondents bring in their own expertise. The role of assessor points to contributing to the overall evaluation of the research proposal. Various tensions were identified within and between roles. Within the role of protector, a tension is experienced between paternalism and autonomy. Between the role of protector and facilitator tensions occur when the value of a study is questioned while risks and burdens for the subjects are negligible. Within the role of assessor, a tension is felt between the implicit nature of judgments and the need for more explicit formulations. Awareness of various roles and responsibilities may prevent one-sided views on MREC work, not only by members themselves, but also by researchers. Tensions within and between the roles require reflection by MREC members. (shrink)

Qualitative description of the movement of objects can be very important when there are large quantity of data or incomplete information, such as in positioning technologies and movement of robots. We present a first step in the combination of fuzzy qualitative reasoning and quantitative data obtained by human interaction and external devices as GPS, in order to update and correct the qualitative information. We consider a Propositional Dynamic Logic which deals with qualitative velocity and enables us (...) to represent some reasoning tasks about qualitative properties. The use of logic provides a general framework which improves the capacity of reasoning. In this way, we can infer additional information by using axioms and the logic apparatus. In this paper we present sound and complete relational dual tableau that can be used for verification of validity of formulas of the logic in question. (shrink)

ContextBehavioral observation scales are important for understanding and assessing social skills. In the context of collaborative problem-solving (CPS) skills, considered essential in the 21st century, there are no validated scales in French that can be adapted to different CPS tasks. The aim of this study is to adapt and validate, by annotating a new video corpus of dyadic interactions that we have collected, two observational scales allowing us to qualitatively assess CPS skills: the Social Performance Rating Scale (SPRS) and the (...) Social Skills of Collaboration Scale (SSC).MethodThe construct validity of these two scales was assessed by exploratory factor analysis and inter-item correlations. We also checked inter-judge agreement using inter-class correlation coefficients. Internal consistency was determined using Cronbach’s alpha and convergent and divergent validity by assessing correlations between the two scales and measures of depression and alexithymia. Finally, the discriminative properties of the two scales were analyzed by comparing the scores obtained by a group of anxious individuals and a non-anxious control group.ResultsThe results show that our two scales have excellent inter-item correlations. Internal consistency is excellent (alpha SPRS =0.90; SSC = 0.93). Inter-rater agreement ranged from moderate to high. Finally, convergent validity was significant with the alexithymia scale, as was divergent validity with the depression scale. Anxious individuals had lower scores on both scales than non-anxious individuals.ConclusionBoth scales show good psychometric properties for assessing social skills relevant to different collaborative tasks. They also identify individuals with difficulties in social interaction. Thus, they could allow monitoring the effectiveness of training social skills useful in CPS. (shrink)

ABSTRACTThe emergence of dimensional analysis in the early nineteenth century involved a redefinition of the pre-existing concepts of homogeneity and dimensions, which entailed a shift from a qualitative to a quantitative conception of these notions. Prior to the nineteenth century, these concepts had been used as criteria to assess the soundness of operations and relations between geometrical quantities. Notably, the terms in such relations were required to be homogeneous, which meant that they needed to have the same geometrical dimensions. (...) The latter reflected the nature of the quantities in question, such as volume vs area. As natural philosophy came to encompass non-geometrical quantities, the need arose to generalize the concept of homogeneity. In 1822, Jean Baptiste Fourier consequently redefined it to be the condition an equation must satisfy in order to remain valid under a change of units, and the ‘dimension' correspondingly became the power of a conversion factor. When these innovations eventually found an echo in France and Great Britain, in the second half of the century, tensions arose between the former, qualitative understanding of dimensions as reflecting the nature of physical quantities, and the new, quantitative conception based on unit conversion and measurement. The emergence of dimensional analysis thus provides a case study of how existing rules and concepts can find themselves redefined in the context of wider conceptual changes; in the present case this redefinition involved a generalization, but also a shift in meaning which led to conceptual tensions.

Although current literature demonstrates how parents benefit from parent empowerment programs, the development of a quantitative measure of parent empowerment has garnered limited attention in parenting research. The goal of this research was therefore to develop and validate a quantitative measure for the assessment of practitioners’ attitudes and competence in parent empowerment. In the process of item generation, the qualitative findings derived from four studies in relation to the perceived outcomes and experiences in parent empowerment were synthesized in the (...) first stage. In the second stage, a list of narratives that articulated different themes of parent empowerment was generated, which resulted in an item pool containing 28 items. In the third stage, the research team converted the 28 items into a survey instrument. In the fourth stage, a first-scale validation study was conducted to explore the factor structure of the initial 28-item questionnaire. The exploratory factor analysis on the first sample of 366 practitioners yielded a twofold factor structure with 17 items, including practitioners’ attitudes in parent empowerment and practitioners’ competence in parent empowerment. In the final stage, a second-scale validation study was undertaken to verify the fit of the twofold factor structure. A confirmatory factor analysis on the second sample of 170 practitioners demonstrated a good model fit. The results of reliability tests for the whole scale and two subscales also indicate satisfactory internal consistency. The Parent EmpowermentviaTransformative Learning Questionnaire (PETLQ) was thus developed and confirmed as a scale with sufficient factorial validity and internal consistency to be used for assessing parenting practitioners’ attitudes and competence in parent empowerment and for evaluating the effectiveness of parent empowerment programs.

Psychological research has shown that cognitive illusions, of which visual illusions are just a special case, are systematic and pervasive, raising epistemological questions about how error in all forms of research can be identified and eliminated. The quantitative sciences make use of statistical techniques for this purpose, but it is not clear what the qualitative equivalent is, particularly in view of widespread scepticism about validity and objectivity. I argue that, in the light of cognitive psychology, the ‘error question’ cannot (...) be dismissed as a positivist obsession, and that the concepts of truth and objectivity are unavoidable. However, they constitute only a ‘minimal realism’, which does not necessarily bring a commitment to ‘absolute’ truth, certainty, correspondence, causation, reductionism, or universal laws in its wake. The assumption that it does reflects a misreading of positivism and, ironically, precipitates a ‘crisis of legitimation and representation’, as described by constructivist authors. (shrink)

In this essay we explore whether and how we should use bibliometrics in hiring, promoting, and granting in the academy. We suggest a Deweyan-Hickmanian pragmatist approach to reflecting on the technology of bibliometrics as a resource for inherently qualitative judgements in these deliberations. We begin with a literature review of current work evaluating the role and use of bibliometrics in the academy, from advocating for them to questioning their construct validity and assessing their limitations and/or dangerous consequences. In the (...) next section, we take a step back and provide a Deweyan philosophical analysis of the validity and practical use of qualitative assessment. In our conclusion we reflect on what pragmatism can teach about recent algorithmic tools used for faculty evaluation. (shrink)

The article describes an approach of systematic, rule guided qualitative text analysis, which tries to preserve some methodological strengths of quantitative content analysis and widen them to a concept of qualitative procedure. First the development of content analysis is delineated and the basic principles are explained (units of analysis, step models, working with categories, validity and reliability). Then the central procedures of qualitative content analysis, inductive development of categories and deductive application of categories, are worked out. The (...) possibilities of computer programs in supporting those qualitative steps of analysis are shown and the possibilities and limits of the approach are discussed. (shrink)

The use of student evaluations of teaching (SET) has become a widespread practice in higher education despite inconclusive evidence reported in the literature around its validity. Not surprisingly, the question of the validity of SET continues to be a current debate in higher education, pointing to the need for more research in this area. This paper is a part of a larger scale study, which aims to contribute to broadening the knowledge and understanding of SET validity by analysing the process (...) within the South East European University (SEEU) in North Macedonia in order to determine whether student evaluations are objective and critical. A likert scale questionnaire, containing 9 questions, was designed for the purpose of the analysis. The questionnaire was sent to all students from the five (5) Faculties: Business and Economics, Law, Contemporary Sciences and Technologies, Contemporary Social Sciences and Faculty of Languages, Cultures and Communications, in both campuses, Tetovo and Skopje. Three hundred and thirty three (333) students participated in the survey. Statistical Package for Social Science (SPSS) was used for analysing the results. Findings revealed that the information students received about the reputation, experience and qualifications of the professors had the highest influence on their perceptions, which in turn influenced the evaluations. As an addition, the present paper also compares two methods on a data set of actual SET. For illustrative purposes, only data from one faculty have been analysed. It is shown that the traditional method of considering the average values can misrepresent a teacher’s performance as it can be highly sensitive to any extreme grades, being either very positive or very negative.

Social attachment can explain well the bond between users and social media, but existing research lacks measures of social attachment scales. To this end, this study takes attachment theory as the basis for scale development. On the basis of the development of multidimensional scales for adult, brand, and local attachment, it combines existing relevant studies on social attachment, selects three representative social media such as TikTok, WeChat, and MicroBlog as theoretical samples, explores the concept and structure of social attachment, and (...) develops a social attachment scale through qualitative interviews and open-ended questionnaires. This study applied SPSS 24.0 and Mplus 7.0 to test the social attachment scale. The findings reveal that social attachment consists of three constructs: social connection, social dependence and social identity, and the scale possesses high reliability and validity. This study has developed and validated a social attachment scale in the context of social software use, realizing a quantitative study of social attachment and providing a basis for future empirical research related to social attachment.

ABSTRACT Thematic analysis is the most widely used method for analysing qualitative data. Recent debates, highlighting the binary distinctions between reflexive TA grounded within the qualitative paradigm and codebook TA with neo-positivist orientations, have emphasized the existence of numerous tensions that researchers must navigate to produce coherent and rigorous research. This article attempts to resolve some of these tensions through developing an approach to TA underpinned by realist philosophy of science. Focusing on interview data, we propose the use (...) of three types of themes and the use of corresponding validity indicators. Using an illustrative example, we outline the conceptual foundations of a realist approach to TA and present recommendations for conducting it in practice. This approach, we claim, reconciles several existing binaries between distinctive types of TA by incorporating the contributions of both for the development of different types of themes. (shrink)

This population study examined the incremental validity of spirituality in predicting burnout among Maltese professional nurses. Cross-sectional and mixed-method design was conducted. Measures in this self-report questionnaire included the Maslach Burnout Inventory, Faith Maturity Scale, Satisfaction with Life Scale, Big Five Inventory and a demographic section, together with a brief qualitative section. Response rate was 78%. All hypotheses were supported. Maltese nurses suffer from high levels of burnout, in particular from low professional accomplishment, high levels of depersonalization, and moderate (...) to high emotional exhaustion. Qualitative data supported these findings and suggested that the physical and moral environment of nurses was conducive to an increase of burnout. Furthermore, multiple regression analysis indicated that spirituality predicted burnout after controlling for personality and well-being. This study suggests that spirituality may be an important potential source of resilience for nurses who risk burnout in their employment. (shrink)

We present a relational proof system in the style of dual tableaux for a multimodal propositional logic for order of magnitude qualitative reasoning to deal with relations of negligibility, non-closeness, and distance. This logic enables us to introduce the operation of qualitative sum for some classes of numbers. A relational formalization of the modal logic in question is introduced in this paper, i.e., we show how to construct a relational logic associated with the logic for order-of-magnitude reasoning and (...) its dual tableau system which is a validity checker for the modal logic. For that purpose, we define a validity preserving translation of the modal language into relational language. Then we prove that the system is sound and complete with respect to the relational logic defined as well as with respect to the logic for order of magnitude reasoning. Finally, we show that in fact relational dual tableau does more. It can be used for performing the four major reasoning tasks: verification of validity, proving entailment of a formula from a finite set of formulas, model checking, and verification of satisfaction of a formula in a finite model by a given object.

BackgroundIn childhood cancer care, healthcare professionals must deal with several difficult moral situations in clinical practice. Previous studies show that morally difficult challenges are related to decisions on treatment limitations, infringing on the child's integrity and growing autonomy, and interprofessional conflicts. Research also shows that healthcare professionals have expressed a need for clinical ethics support to help them deal with morally difficult situations. Moral case deliberations (MCDs) are one example of ethics support. The aim of this study was to describe (...) the MCD-related outcomes that healthcare professionals in childhood cancer care considered important, before MCDs were implemented, in order to facilitate the implementation of MCDs in childhood cancer care in Sweden.MethodsThis study is based on qualitative data. Healthcare professionals, mostly representing registered nurses, nursing assistants and physicians, working at childhood cancer care centres in Sweden, were invited to respond to the translated and content validated European MCD Outcomes Instrument, before participating in regular MCDs. Answers to the main open-ended question, included in the questionnaire, was analysed according to systematic text condensation.ResultsData was collected from 161 responses from the healthcare professionals. The responses included healthcare professionals’ perceptions of which MCD-related outcomes they found important for handling moral challenges. Three different themes of important outcomes from the analysis of the data are presented as follows:Interprofessional well-being in team interactionson a team level;Professional comfort when dealing with moral challengeson a personal level; andImproved quality of care for the child and the familyon a care level.ConclusionsHealthcare professionals in childhood cancer care considered it important that ethics support could enhance the well-being of interprofessional teams, support healthcare professionals on an individual level and improve quality of care. The results of this study can be used in current and future training for MCD-facilitators. When knowing the context specific important MCD-outcomes, the sessions could be adapted. Managers in childhood cancer care would benefit from knowing about the specific important outcomes for their target group because they could then create relevant working conditions for clinical ethics support.

This study was aimed at constructing and validating a measurement to assess students’ responses to faculty incivility. A mixed-method approach was implemented. A qualitative method was used to analyze responses to FI as described by college students. The results foregrounded four categories—exit, voice, loyalty, and neglect—in line with the theoretical EVLN model for describing reactions to stressful conditions. The students’ descriptions were formulated as short items. Following the qualitative results, a quantitative method was used to validate the developed (...) EVLN questionnaire and to assess the relationships between student characteristic variables, experiences of FI, and the four EVLN responses. Data were gathered from 744 undergraduate college students, yet only those who experienced FI to some extent were selected to assess reactions to FI. According to the structural equation modeling results, FI was positively linked solely to the exit response. In addition, the findings indicated that merely the active FI subfactor was linked to the exit factor. Interpretation of these results, their congruence within the context of the theoretical frameworks, limitations, and practical implications are discussed. (shrink)

The major premise of this paper is a well accepted definition taken from the mathematics of information theory; information exists only when uncertainty is reduced by some amount.

Qualitative research carried out within human science must provide justification for its findings. However, the justification of empirical claims concerning human meanings has to be approached in new ways: Quantitative procedures of validation or the use of experimental control are inappropriate. Many researchers have attempted to follow Schutz's ''postulate of adequacy," which lays down as a condition of acceptability of a scientific account of human action that it be understandable by the actor in terms of commonsense interpretation of (...) everyday life. For instance, Harré suggests "validating" descriptions by ensuring that subjects of the research approve them. Against this approach, it is insisted that human science research is essentially an interpersonal process, and that therefore research activities cannot avoid such Goffmanesque features of self-presentation as resistance to being understood and eager acceptance of understanding, which are both pervasive possibilities of all social interaction. Thus, the research participant's agreement or disagreement cannot be taken as evidence as to the adequacy of a qualitative research description or interpretation. (shrink)

Pregnant people experience moral judgment in healthcare settings that may be coded into clinical documentation. Stigmatizing language in medical records transmits bias between clinicians, potentially exacerbating disparities in maternal morbidity and mortality. We examined obstetrical records from 100 randomly selected patients who received prenatal and delivery care in an academic hospital system. Qualitative analysis sought to identify linguistic features conveying negative attitudes or moral judgment, revealing themes of epistemic injustice: (1) discrediting patient testimony as incompetent, unreliable, and hysterical; (2) (...) unnecessary details that are objectifying, stigmatizing, or unprofessional; and (3) judgments of maternal fitness, where women are labeled “bad mothers” by emphasizing neglectful, selfish, and debauched characteristics. We conclude by advocating for further validation of our findings, revisiting medical education paradigms, and supporting the development of natural language processing (NLP) technologies to detect and intercept stigma.

Soundscapes affect people’s health and wellbeing and contribute to the perception of environments as restorative. This paper continues the validation process of a previously developed Perceived Restorativeness Soundscape Scale (PRSS). The study takes a novel methodological approach to explore the PRSS face and construct validity by examining the qualitative reasons for participants’ numerical responses to the PRSS items. The structure and framing of items are first examined, to produce 44 items which are assessed on a seven-point Likert agreement (...) scale, followed by a free format justification. Ten English speaking participants completed the PRSS interpretation questionnaire in two cafes in Montréal, Canada. Interpretation of participant free format responses led to six themes, which related to either the individual (personal attributes, personal outcomes), the environment (physical environment attributes, soundscape design) or an interaction of the two (behaviour setting, normality and typicality). The themes are discussed in relation to each Attention Restoration Theory (ART) component, namely Fascination, Being-Away, Compatibility, and Extent. The paper concludes by discussing the face and construct validity of the PRSS, as well as the wider methodological and theoretical implications for soundscape and attention restoration research, including the terminology importance in items measuring ART components and the value of all four components in assessing perceived restorativeness.

The technological possibilities for new data sources in media psychology, such as online live recordings, called Live Streaming, are growing continuously. These sources do not only offer plentiful quantitative material but also a fairly new access to ecologically valid and unobtrusive observation of problem-solving and decision-making processes. However, to exploit these potentials, epistemological and methodological reflection should guide research. The availability of Big Data and naturally occurring data sets allows to revise the historical controversies on the eligibility of self-description. Drawing (...) on such reflections, media psychology can contribute to renovate well established research methods, such as think aloud protocols, in order to enhance their empirical claims. Apart from other confident attempts to improve these methods, phenomenology and ethnomethodology offer a fruitful account to develop innovative data sources for self-description. Yet, this approach does not support a recurrence of self-description’s previous application but proposes an epistemological shift towards more subtle observations. In order to convey the potentials of media psychology, the risk of repeating classical mistakes, such as introspectionism, have to be regarded. Beyond these fallacies, however, modern digital technology holds encouraging potentials which have already partly been sighted by video gaming research. Due to the similarity of digital environments to laboratory setups, there remains to be a continuity from offline to online research, from traditional data to Big Data. Nevertheless, a true advance into new possibilities requires understanding the qualitative meaning of such data. (shrink)

The evolution of Web 2.0 and social networks has led to the increased use of enterprise social media platforms, making online interactions more common in organizations. However, few studies have researched online interactions in organizational context. This study addressed this gap using two research phases: a qualitative phase and a quantitative phase. The qualitative study phase identified two dimensions of online interaction: employee–employee online interaction and employee–platform online interaction. The employee–employee online interaction assessed responsiveness and suitability. The employee–platform (...) online interaction assessed usefulness, applicability, and ease of use. The quantitative study phase applied a proposed conceptual framework derived from the qualitative study to create and validate measures for a new online interaction scale. This was done using a systematic scale development process. Measuring online interaction can help drive future quantitative research, providing an instrumental basis for further exploring the scientific management practice elements that govern employee psychology and behavior in cyberspace.

Technical and tactical actions are decisive in terms of badminton player competitive performance. The main objective of this research was to design, validate, and estimate the reliability of an observational instrument for the analysis of the tactical and technical actions in individual badminton. The process was carried out in four different steps: first, there was a review of the scientific literature and a preliminary list of variables was made; second, a qualitative and quantitative assessment was completed by 10 badminton (...) expert judges; in the third step, the content validity was estimated using Aiken’s V coefficient; finally, intra-observer reliability and interobserver reliability were tested by two observers specialized in badminton using the Cohen’s Kappa coefficient and the intraclass correlation coefficient. Strokes were used as the unit of measure by our observational instrument; every time badminton players hit the shuttlecock, 22 variables are observed. The minimum Aiken’s value was 0.58, and reliability was 0.63. In spite of these values, none of the variables had to be removed, but there were modifications in terms of drafting in some of them. The main findings confirmed the validity and the usefulness of this instrument. (shrink)

Particularly, fear is expected to generate significant psychological burden on individuals and influence on either unsafe behavior that may hinder recovery efforts or virus-mitigating behaviors. However, little is known about the properties of measures to capture them in research and clinical settings. To resolve this gap, we evaluated the psychometric properties of a novel measure of fear of illness and viruses and tested its predictive value for future development of distress. (...) We extracted a random sample of 450 Chilean adult participants from a large cross-sectional survey panel and invited to participate in this intensive longitudinal study for 35 days. Of these, 163 ended up enrolling in the study after the demanding nature of the measurement schedule was clearly explained to them. For this final sample, we calculated different Confirmatory Factor Analyses (CFA) to evaluate the preliminary proposed structure for the instrument. Complementarily, we conducted a content analysis of the items to qualitatively extract its latent structure, which was also subject to empirical test via CFA. Results indicated that the original structure did not fit the data well; however, the new proposed structure based on the content analysis did. Overall, the modified instrument showed good reliability through all subscales both by its internal consistency with Cronbach’s alphas ranging from 0.814 to 0.913, and with test–retest correlations ranging from 0.715 to 0.804. Regarding its convergent validity, individuals who scored higher in fears tended to also score higher in depressive and posttraumatic stress symptoms at baseline. Furthermore, higher fears at baseline predicted a higher score in posttraumatic stress symptomatology 7 days later. These results provide evidence for the validity, reliability, and predictive performance of the scale. As the scale is free and multidimensional potentially not circumscribed to COVID-19, it might work as a step toward understanding the psychological impact of current and future pandemics, or further life-threatening health situations of similar characteristics. Limitations, practical implications, and future directions for research are discussed. (shrink)

Validity is a central principle of assessment relating to the appropriateness of the uses and interpretations of test results. Usually, one of the inferences that we wish to make is that the score reflects the extent of a student?s learning in a given domain. Thus, it is important to establish that the assessment tasks elicit performances that reflect the intended constructs. This research explored the use of three methods for evaluating whether there are threats to validity in relation to the (...) constructs elicited in international A level geography examinations: (a) Rasch analysis; (b) analysis of processes expected and apparent when students answer questions; and (c) qualitative analysis of responses to items identified as potentially problematic. The results provided strong evidence to support validity with regard to the elicitation of constructs although one question part was identified as a threat to validity. Strengths and weaknesses of the methods can be identified. (shrink)

Driven by an impetus to standardize, numerous checklists have been devised to address quality in qualitative research, but these standards and the mindset driving them offer no language with which to speak about taste, or the aesthetic sensibilities that play such a key role in evaluating the goodness of any object. In this article, quality appraisal in qualitative research is considered in the context of taste, that is, in the discernment involved in judging the value of research and (...) in the recognition of the key role reviewer preferences, sensibilities and membership in one or more taste communities play in these judgements. The evaluation of a study is accomplished by evaluating one or more reports from that study, and such reports may be conceived as art forms amenable to the same criteria for appraisal as poems or paintings. Taste implies judgements about the quality of objects and a person's ability to sift through and select from a store of knowledge that knowledge appropriate to judge its value. What binds a community of practitioners (here reviewers of qualitative studies) together is taste‐making, or the constant refinements of judgements concerning what constitutes good and bad practice.

Many problems that arise when providing pharmacy services may contain some ethical components and the aims of this study were to develop and validate a scale that could assess difficulties of ethical issues, as well as the frequency of those occurrences in everyday practice of community pharmacists. Development and validation of the scale was conducted in three phases: generating items for the initial survey instrument after qualitative analysis; defining the design and format of the instrument; validation of (...) the instrument. The constructed Ethical Issue scale for community pharmacy setting has two parts containing the same 16 items for assessing the difficulty and frequency thereof. The results of the 171 completely filled out scales were analyzed. The Cronbach’s α value of the part of the instrument that examines difficulties of the ethical situations was 0.83 and for the part of the instrument that examined frequency of the ethical situations was 0.84. Test–retest reliability for both parts of the instrument was satisfactory with all Interclass correlation coefficient values above 0.6,. The 16-item scale, as a self assessment tool, demonstrated a high degree of content, criterion, and construct validity and test–retest reliability. The results support its use as a research tool to asses difficulty and frequency of ethical issues in community pharmacy setting. The validated scale needs to be further employed on a larger sample of pharmacists. (shrink)

Background Healthcare worker retention and burnout are confounding issues. Trust among workers and their employer, that is, organization, is an important yet underexplored concept in research. Research aim The aim of this qualitative study is to explore organizational actions and systems that promote or denigrate trust among registered nurses and patient care aides (aides). Research design The study uses the Model of Psychological Contract as a theoretical framework. Focus groups were conducted to explore the concept of organizational trust and (...) the consequences of broken trust. Participants Registered nurses (RNs) (n=6) and aides (n=6) participated in the study. Six focus groups (three RN and three aide) were conducted, with two participants per group. Focus groups were conducted online. Ethical considerations The study's methods were reviewed by the University of Pittsburgh Institutional Review Board. Findings Among RNs and aides, a sense of trust and feeling valued were important to their sense of relationship with their employers. Trust was breached when resources were scarce, employees did not feel validated and listened to, and problems were not addressed. RNs and aides described feeling devalued when compensation practices were unjust or inequitable, they had limited autonomy, and the employer created an organizational climate where business needs superceded human caring. Consequences of trust breach included burnout, dejection, and feelings of non-belonging. Discussion Tangible organizational resources (compensation and staffing) and intangible resources (value, respect, autonomy) are important to RNs and aides alike. Inability to provide these resources diminishes trust and even causes a sense of betrayal. Conclusion Future research can explore the concepts of organizational justice and interventions to restore lost trust and improve healthcare worker well-being. This is one of only a few identified studies to explore organizational factors and well-being among aides and more research among this healthcare worker population is warranted. (shrink)

BackgroundThe consent process for a genetic study is challenging when the research is conducted in a group stigmatized because of beliefs that the disease is familial. Podoconiosis, also known as 'mossy foot', is an example of such a disease. It is a condition resulting in swelling of the lower legs among people exposed to red clay soil. It is a very stigmatizing problem in endemic areas of Ethiopia because of the widely held opinion that the disease runs in families and (...) is untreatable. The aim of this study was to explore the impact of social stigma on the process of obtaining consent for a study on the genetics of podoconiosis in Southern Ethiopia.MethodsWe adapted a rapid assessment tool validated in The Gambia. The methodology was qualitative involving focus-group discussions (n = 4) and in-depth interviews (n = 25) with community members, fieldworkers, researchers and staff of the Mossy Foot Treatment and Prevention Association (MFTPA) working on prevention and treatment of podoconiosis.ResultsWe found that patients were afraid of participation in a genetic study for fear the study might aggravate stigmatization by publicizing the familial nature of the disease. The MFTPA was also concerned that discussion about the familial nature of podoconiosis would disappoint patients and would threaten the trust they have in the organization. In addition, participants of the rapid assessment stressed that the genetic study should be approved at family level before prospective participants are approached for consent. Based on this feedback, we developed and implemented a consent process involving community consensus and education of fieldworkers, community members and health workers. In addition, we utilized the experience and established trust of the MFTPA to diminish the perceived risk.ConclusionThe study showed that the consent process developed based on issues highlighted in the rapid assessment facilitated recruitment of participants and increased their confidence that the genetic research would not fuel stigma. Therefore, investigators must seek to assess and address risks of research from prospective participants' perspectives. This involves understanding the issues in the society, the culture, community dialogues and developing a consent process that takes all these into consideration. (shrink)

BackgroundDespite rapid growth of the scientific literature, no consensus guidelines have emerged to define the optimal criteria for editors to grade submitted manuscripts. The purpose of this project was to assess the peer reviewer metrics currently used in the surgical literature to evaluate original manuscript submissions.MethodsManuscript grading forms for 14 of the highest circulation general surgery-related journals were evaluated for content, including the type and number of quantitative and qualitative questions asked of peer reviewers. Reviewer grading forms for the (...) seven surgical journals with the higher impact factors were compared to the seven surgical journals with lower impact factors using Fisher’s exact tests.ResultsImpact factors of the studied journals ranged from 1.73 to 8.57, with a median impact factor of 4.26 in the higher group and 2.81 in the lower group. The content of the grading forms was found to vary considerably. Relatively few journals asked reviewers to grade specific components of a manuscript. Higher impact factor journal manuscript grading forms more frequently addressed statistical analysis, ethical considerations, and conflict of interest. In contrast, lower impact factor journals more commonly requested reviewers to make qualitative assessments of novelty/originality, scientific validity, and scientific importance.ConclusionSubstantial variation exists in the grading criteria used to evaluate original manuscripts submitted to the surgical literature for peer review, with differential emphasis placed on certain criteria correlated to journal impact factors.

This paper is expected to introduce a novel memductor-based chaotic system. The local dynamical entities, such as the basic dynamical behavior, the divergence, the stability of equilibrium set, and the Lyapunov exponent, are all investigated analytically and numerically to reveal the dynamic characteristics of the new memductor-based chaotic system as the system parameters and the initial state of memristor change. Subsequently, an active control method is derived to study the synchronous stability of the novel memductor-based chaotic system through making the (...) synchronization error system asymptotically stable at the origin. Further to these, a memductor-based chaotic circuit is designed, realized, and applied to construct a new memductor-based secure communication circuit by employing the basic electronic components and memristor. Furthermore, the design principle of the memductor-based chaotic circuit is thoroughly analyzed and the concept of “the memductor-based chaotic circuit defect quantification index” is proposed for the first time to verify whether the chaotic output is consistent with the mathematical model. A good qualitative agreement is shown between the simulations and the experimental validation results. (shrink)

Background:Reducing the incidence and negative consequences of concussion among youth athletes is a public health priority. In 2010, Massachusetts passed legislation aimed at addressing the issue of concussions in school athletics. We sought to understand local-level implementation decisions of the Massachusetts concussion law.Methods:A qualitative multiple-case study approach was utilized. Semi-structured interviews with school-employed actors associated with the law's implementation were used for analysis. Interview data were subjected to a conventional content analysis.Results:A total of 19 participants from 5 schools were (...) interviewed. Schools were purposefully selected from communities varying in socioeconomic status and population. Participants included 5 athletic directors, 5 coaches, 4 athletic trainers, 4 school nurses, and 1 health and wellness coordinator. Eight themes emerged regarding specific ways schools have implemented the law. Six themes emerged regarding factors influencing implementation.Conclusions:All cases employ neurocognitive testing as a means to assess concussions, place decision-making authority in athletic trainers' hands, and use a 30-minute online video to disseminate concussion education. Employing athletic trainers could pose challenges to school districts with limited financial capacity, as financial assistance from the state is not provided under the law. The validity of neurocognitive testing and the effectiveness of online concussion training need further study. Cooperation from student athletes, their parents, and physicians is necessary for full implementation of the law. (shrink)

The present article explores problems of descriptive reporting, relativism, and the lack of systematic follow-up of qualitative research. Such issues are discussed in relation to components of phenomenologically based research reports, with emphasis on the articulation of the research approach, and steps to facilitate validation. The value of a descriptive science derived from phenomenological principles is discussed as forming a common ground for initial qualitative inquiry, while providing a critically reflective base upon which rational consensus can be (...) developed. I suggest that the values of follow-up, tentativeness, and humility in research reporting, and a rational framework of critical validation, constitute a common core of science. In addition, phenomenological tenets are discussed as providing a corrective to the uncritical search for absolutes, or the "anything counts" conception of relativistic movements. (shrink)

Incidental findings and secondary findings, being results that are unrelated to the diagnostic question, are the subject of an important debate in the practice of clinical genomic medicine. Arguments for reporting these results or not doing so typically relate to the principles of autonomy, non-maleficence and beneficence. However, these principles frequently conflict and are insufficient by themselves to come to a conclusion. This study investigates empirically how ethical principles are considered when actually reporting IFs or SFs and how value conflicts (...) are weighed. A qualitative focus group study has been undertaken, including a multidisciplinary group of professionals from Belgian centres for medical genetics. The data were analysed thematically. All eight Belgian centres participated in this study. Ethical values were frequently referred to for disclosure policies on IFs and SFs. Participants invoked respect for patient autonomy to support the disclosure of IFs and opt-out options for IFs and SFs, non-maleficence for the professional delineation of reportable IFs and opt-out options for IFs and SFs and beneficence for the mandatory reporting of actionable IFs, the delineation of reportable IFs and a current decline of actively pursued SFs. Professional assumptions about patients’ genetic literacy were an important factor in the weighing of values. In line with the traditional bioethical discourse, the mandatory reporting of actionable IFs might be interpreted as a “technological, soft paternalism”. Restricting patients’ choices might be acceptable, but then its motives should be valid and its beneficent outcomes highly plausible. Hence, the presuppositions of technological, soft paternalism - patients’ inability to make informed decisions, normative rationality, the efficacy of beneficent outcomes and the delineated spectrum of beneficence - should be approached critically. Moreover, distributive justice should be considered an important value in the delineation of the current scope of the ethical debate on IFs and SFs. This study of guiding values may stimulate the debate on the ethical grounds for a solid policy on IFs and SFs internationally. (shrink)

The COPE Inventory is the most frequently used measure of coping; yet previous studies examining its factor structure yielded mixed results. The purpose of the current study, therefore, was to validate the factor structure of the COPE Inventory in a representative sample of over 2,000 adults in Slovakia. Our second goal was to evaluate the external validity of the COPE inventory, which has not been done before. Firstly, we performed the exploratory factor analysis with half of the sample. Subsequently, we (...) performed the confirmatory factor analysis with the second half of the sample. Both factor analyses with 15 factor solutions showed excellent fit with the data. Additionally, we performed a hierarchical factor analysis with fifteen first-order factors and three second-order factors which showed good fit with the data. Moreover, the COPE Inventory’s external validity was evaluated using consensual qualitative research analysis on data collected by in-depth interviews. Categories of coping created using CQR corresponded with all COPE first-order factors. Moreover, we identified two additional first-order factors that were not present in the COPE Inventory: self-care and care for others. Our study shows that the Slovak translation of the COPE Inventory is a reliable, externally valid, and well-structured instrument for measuring coping in the Slovak population. (shrink)

The importance of ethical leadership in organizations has been increasingly recognized, especially as a shield against unethical employee behaviors and corporate misconducts. Ethical leadership has been theorized to include two aspects: “moral person” and “moral manager.” This conceptualization resonates well with Chinese teachings of Confucius on leadership and management—namely xiuji and anren. Based on the theoretical framework of ethical leadership, we develop and validate a new ethical leadership measure. Through qualitative studies and five quantitative studies, we establish the reliability (...) and convergent, discriminant, and predictive validities of the ELM in a Chinese context. In addition, using a US sample, we find that the ELM has partial measurement invariance across Chinese and American contexts. (shrink)
