Family stories are theorized to be a critical part of adolescents' emerging identity and well-being, yet to date we know very little about adolescents' knowledge of their family history and intergenerational family stories. In this study, we expand our previous findings that pre-adolescent children who know more about their family history display higher levels of emotional well-being. Sixty-six broadly middle-class, mixed race, 14- to 16-year old adolescents from two-parent families were asked to complete a measure of family history, the "Do You Know..." scale (DYK), as well as multiple standardized measures of family functioning, identity development and well-being. Adolescents who report knowing more stories about their familial past show higher levels of emotional well-being, and also higher levels of identity achievement, even when controlling for general level of family functioning. Theoretical and clinical implications of these findings are discussed.
