Relationships between parenting styles, academic performance, and the mediating effects of motivation, goal orientation, and self-efficacy were examined. One hundred forty-eight high school students participated, including 58 males and 90 females. The Parenting Style/Parental Involvement Questionnaire was used to measure students' perceptions of their parents' parenting styles. The Intrinsic-Extrinsic Orientation Scale measured students' motivation. The Patterns of Adapted Learning Survey measured participants' goal orientation and academic self-efficacy. Adolescents who reported their parents as having a more authoritative parenting style were found to demonstrate more intrinsic motivation in their academic pursuits. Future implications for intervention and research are discussed. (Contains 2 tables.)
