The present study examined the way in which children attending Orthodox Jewish schools internalize the value of both their Jewish studies and secular studies, as well as the value of Jewish cultural practices. A distinction was made between identified internalization, where children perceive Jewish studies and Jewish culture to be an important part of their sense of self, and introjected internalization, where children participate in Jewish studies and Jewish culture because they feel like they "ought to" or because of external pressures. Primary identified reasons for their Jewish studies and Jewish cultural practices were significantly associated with positive self and teacher ratings of adjustment; internalization of secular studies was unrelated to adjustment. The study also found that parental support of autonomy, which involves allowing children some latitude in making decisions for themselves regarding religious issues, was associated with greater identification. Together, these results highlight the importance of autonomy-supportive parenting in promoting identification of adolescents' Jewish identity. (Contains 3 tables.)
