This study investigated the relations of maternal and paternal attachment, parenting styles, and career locus of control to college students' career decision self-efficacy and explored whether these relations differed by student gender. Data analysis using hierarchical multiple regression revealed that attachment was relevant for females' career decision self-efficacy but not for men's. Authoritarian parenting styles were predictive of women's career decision self-efficacy. Locus of control was important for male students but not for females. (Contains 4 tables.)
