Parental support and provision of structure are linked to positive outcomes in adolescents, yet the influence of parental involvement on identity development during adolescence has not been clearly established. The present study examined the relationship between adolescent identity achievement and parental support, social monitoring, and school monitoring among 10th and 12th graders. It was hypothesized that parental support and monitoring would be associated with higher identity achievement. It was also our goal to clarify the relationship between gender and adolescent identity achievement. The girls in this study reported higher levels of each of the positive parental involvement factors than did boys, but there were no gender differences in identity achievement. Parental support and monitoring of social and school activities were significant predictors of identity achievement across age and gender. Results also suggested that the association between parental involvement and identity achievement differs by gender and it changes as a function of age.
