Abstract
This comparative study shows biases relative to client age, gender and behaviour demon strated by 268 female nurse subjects. A repeated measures design was utilized. All three main effects were significant (p < 0.001) for how respondents predicted that they would react to various clients and also how they predicted that their colleagues would react. Most two-way and three-way interaction effects were significant. Subjects demonstrated more favourable reactions to nice, young, male clients and least favourable reactions to not nice, old, male clients. Study subjects predicted more favourable self-reactions to simulated clients than for their colleagues. What should be important to every professional as a result of this study is the need to be aware of self-biases, which may cause errors in decision-making and nursing care interventions and lead to ethical violations with clients
