This study investigated the relations among parent-child relationship, school adjustment and self-concept in adolescence. In addition, interaction effects of parent-child relationship and school adjustment on adolescent self-concept were examined. The major results of this study were as follows: 1. Parent-child relationship and school adjustment were positively associated with self-esteem. The better parent-child relationships they perceive, the higher self-concept they have. The better school adjustment they experience, the higher self-concept they have. 2. There were interaction effects of parent-child relationships and school adjustment on self-concept. Adolescents whose parent-child relationships were poor had higher self-concept when they adjusted to school well. There were little differences in self-concept as a function of the school adjustment when their parent-child relationships were good. These findings indicate that experience in the family and school domains interact in their associations with adolescent self-concept.
