Peer Stress Spills Over to Family Stress in the Context of Emotion Regulation Difficulties: A Daily Diary Study with Chinese Adolescents.

Conflict in peer and family relationships becomes more common in the adolescent period when compared to previous developmental periods. These typical developmental challenges can be exacerbated in the context of poor emotion regulation skills. Using daily diary data, the current study examined the stress spillover effects of peer and family stress on one another, as well as the moderating role of emotion regulation challenges (i.e., emotional inhibition, dysregulation). A sample of 310 Chinese adolescents (M = 13.02 years, SD = 0.76 years, 50.7% boys) completed an initial measure of emotion regulation difficulties, then reported on peer and family stress for 10 consecutive weekdays. Results indicated that there was an overall same-day peer stress spillover effect in which adolescents' peer stress on a given day was negatively associated with later conflictual interactions with their parents. Further, the relation between peer stress and same- and next-day family stress was exacerbated in the context of high levels of emotional inhibition. Family stress did not significantly relate to next-day peer stress, nor was this association moderated by difficulties with emotion regulation. These results highlight the temporal sequence of daily peer-to-family stress spillover. Though emotional inhibition may be culturally adaptive for maintaining interpersonal harmony, it can be maladaptive in managing stress for Chinese adolescents.
