Abstract

Purpose: The purpose of this mixed-methods study was to determine whether Facebook use affects biological response to stress and to characterize participants’ use of Facebook during a stressful event. Methods: College students completed a modified Trier Social Stress Test including video recording. Participants were randomly assigned to the Facebook group or control group (no preparatory materials). Pulse and salivary cortisol were measured and compared using t tests. Trained coders assessed videos for 13 common Facebook actions and categorized them as purposeful (tool based) or nonpurposeful (distraction); pulse was compared between groups using Fisher’s exact test. Results: Of 41 participants, 14 (36%) were male and 36 (88%) were Caucasian, mean age was 19.6 ± 1.4 years; 19 participants were randomized to the Facebook group. Comparing Time 1 and Time 3, there were no significant differences in cortisol or pulse change between the Facebook group and the control group. However, males in the control group had a mean pulse reduction of −3.5 ± 0.2 bpm between baseline and Time 3; males in the Facebook group had a mean pulse increase of 10 ± 8.6 bmp (p =.01). Overall, 58.8% of videos were categorized as primarily tool based. Participants who primarily demonstrated distracted use of Facebook had higher than average pulse rates at Time 3 (mean 85.1 vs. 73.6 bpm, p =.03). Discussion: Male Facebook users and participants who demonstrated distracted Facebook use showed increased biologic signs of stress during a stressful event. Some college students may find Facebook use detrimental to performance in stressful situations, but this may vary by gender and type of use.
