The rate at which adolescents' social self-efficacy levels can be predicted by variables such as the level of the adolescents' attachment to their parents and their peers, problem-solving skills, learned resourcefulness, perceived marital adjustment of their parents, and their mothers' interpersonal relationships was examined. Volunteer high school students (N = 194), and their mothers were the participants. Students completed the Social Self-Efficacy Expectation Scale for Adolescents (SSES-A; Bilgin, 1999). Data were collected through the Inventory of Parent Attachment (IPA; Hortacsu & Oral, 1991), the Inventory of Peer Attachment (IPA; Hortacsu & Oral, 1991), the Interpersonal Relationship Scale (IPRS; Sahin, Durak, & Yasak, 1994), the Problem Solving Inventory (PSI; Savsir & Sahin, 1997), Rosenbaum's (1980) Learned Resourcefulness Schedule (RLRS), and the Perceived Marital Adjustment Questionnaire (PMAQ; Akkapulu, 2005). The result of the stepwise regression analyses revealed that learned resourcefulness, problem-solving skills, perceived marital adjustment, the level of peer attachment, the mothers' nourishing interpersonal relations, and parental attachment levels, were all significant predictors of social self-efficacy.
