This study explored the effects of family background variables on coping styles, and the contribution of coping styles and locus of control to the overall adjustment of older adolescents. The objectives of this study were to develop a Canadian adaptation of the Seiffge-Krenke Adolescent Coping Style Scale; to explore the influences of family and personality variables on coping styles; to explore the influences of coping styles on overall adjustment; and to compare the influences of coping styles and locus of control. The subjects were 611 male and female Canadian university students between ages 17 and 18, who were required to complete the coping-styles scale along with other scales, some of which were consolidated into factor scores or averaged z-scores. The results suggest that family background significantly influences adolescents' coping style and that coping style is a substantial contributor to overall adjustment. (MOK)
