  • Both peer influences and genetics have been linked to gaming addiction (GA) in adolescents and young adults. This study examined the gene-environment interplay (gene-environment correlation [rGE] and gene-environment interaction [G x E]) between close friends’ gaming (CFG) and GA among South Korean twins. A total of 1462 twins aged 15–29 years (mean = 22.63 ± 2.8 years) completed an online survey that included a 20-item GA measure and a single item assessing CFG. Bivariate Cholesky model-fitting analysis was conducted to examine evidence for rGE in the relationship between GA and CFG. Bivariate G x E model-fitting analysis was performed to determine evidence for G x E effects. A significant genetic correlation (rg = .37; 95% CI [0.24, 0.49]) between GA and CFG supported the role of gene-environment correlation, suggesting that individuals with a genetic predisposition for GA may selectively associate with peers who frequently engage in gaming. The model testing G x E effects indicated that environment-environment interaction was present in the relationship between CFG and GA, such that CFG increased nonshared environmental effects on GA. This pattern provided evidence for peer socialization effects, wherein peers influence the development of GA independently of genetic risk.

  • Summary

    Coping refers to the multitude of actions individuals use to manage stressful encounters. In this chapter, we first describe stressful peer events during childhood and adolescence (e.g., bullying, rejection, victimization), focusing on their impact on mental health but also how they can provide opportunities to apply coping skills. Second, we address how peer relationships, at the group and the dyadic level, are prime settings for the development of coping by considering 1) the soothing and distracting presence of peers, 2) the selection of peers, and 3) the socialization of emotion and coping that can occur within peer interactions and relationships via processes of support, communication, and disclosure. We end with brief notes on the important consideration of the quality of peer relationships and the usefulness of considering gender (and cultural) differences, especially focusing on moderation effects to uncover whether these processes differ across gender and cultural subgroups.
