Affective Responsivity to Daily Stressors is Amplified in Young Females

Despite mounting evidence that young adults experience greater exposure and affective responsivity to daily stressors than middle-aged and older adults, few studies have examined potential sex differences in these daily stress processes in young adults. We tested the hypotheses that young women would experience (1) a greater percentage of days with at least one daily stressor event and (2) exaggerated negative and positive affective responsivity to daily stressors compared to young men. Young adults (n = 215) completed a daily web-based interview for eight consecutive days to assess multiple dynamic aspects of daily stress processes. Women experienced a greater frequency of daily stressor days. Further, the magnitude of the difference in both negative and positive affect between stressor-free and stressor days were greater in young women compared to young men. Greater exposure and amplified affective responsivity to daily stressors may potentially contribute to increased susceptibility to adverse psychological outcomes in young women.
