Feeling socially connected to others is linked to better emotion regulation in adolescent girls' daily lives: An ecological momentary assessment study.

Developing effective emotion regulation ability to manage negative emotion (NE) is critical during adolescence. Social baseline theory posits social connectedness may impact adolescents' everyday emotion regulation. This study examined the relation between social connectedness and NE after a negative social interaction (emotion regulation) and whether contextual factors moderate the association. Adolescent girls (N = 114; M = 12.26, SD = 0.8) from a midsized Midwestern U.S. city (67.5% White, 19.3% Black/African American, 9.6% biracial, 1.8% Asian, 1.8% Native American/other race; 8.8% Latinx) completed a 16-day ecological momentary assessment (EMA) protocol, reporting current NE, current social context and social connectedness, peak NE, and receipt of co-regulatory support. Multilevel models were used to examine direct associations of social connectedness on emotion regulation, defined as current NE regressed on peak NE, and moderation of the social connectedness-emotion regulation association by social context, co-regulatory support, and adolescent shyness. Greater within- and between-person social connectedness was associated with better emotion regulation (greater reductions in NE). However, the within-person association depended on girls' social context: Compared to being with solely peers and/or non-family, being with family was associated with a weaker association between social connectedness and emotion regulation. Similarly, receiving in-the-moment co-regulatory support was associated with a weakened link between within-person social connectedness and emotion regulation, which appeared to be driven by reports of co-rumination. Results indicate that social connectedness is associated with better emotion regulation among girls, particularly in interactions with peers and non-family compared to family, highlighting the value of social connection with peers and non-family members. However, co-rumination disrupts the benefits of social connectedness, suggesting social connectedness is not beneficial during maladaptive co-regulatory processes.
