Adolescents' Prosocial Behavior Toward Family, Friends, and Strangers: A Person‐Centered Approach

This study examined longitudinal change in adolescents' prosocial behavior toward family, friends, and strangers. Participants included 491 mother–child dyads (average age of child at Time 1 = 11.5, 67% European American). Growth mixture modeling suggested that prosocial behavior toward family was generally stable or decreased over time, while prosocial behavior toward friends increased over time. However, findings highlighted unique developmental trajectories within subgroups of adolescents for prosocial behavior toward family and friends and found that maternal warmth and adolescent sympathy, self‐regulation, and gender consistently distinguished between groups. Discussion focuses on the need for a more multidimensional approach to prosocial development.
