The results of two studies are reported. Study I involved the development of the Inventory of Parent and Peer Attachment (IPPA), a self-report instrument for use with adolescents. Subject were 179 college students aged 16-20 years. Item content of the instrument was suggested by attachment theory's formulations concerning the nature of feelings toward attachment figures. In Study II, the convergent validity of the IPPA was examined. Also, a hierarchial regression model was employed to investigate the association between quality of attachment and self-esteem, life-satisfaction, and affective status. Respondents were 86 adolescents from the Study I sample. As hypothesized, perceived quality of both parent and peer attachments was significantly related to psychological well-being. Results of the development of a theoretically focused, exploratory classification scheme indicated that adolescents classified as highly securely attached reported greater satisfaction with themselves, a higher likelihood of seeking social support, and less symptomatic response to stressful life events.
