This study examined the extent to which the quality of parent and peer attachments related to early adolescents' life satisfaction (LS), whether peer attachment served as a mediator between parent attachment and LS, and potential gender differences. Total of 587 middle school students in grades 6 through 8 participated. Although both parent and peer attachment positively related to LS, parent attachment was the stronger unique predictor. There was no significant difference between males and females in levels of parent attachment; however, females reported higher levels of attachment to peers. This study also found that early adolescents were more attached to their mothers than their fathers. Finally, peer attachment partially mediated the relationship between parent attachment and LS, but only for females. Implications for gender-specific intervention programs are discussed.
