Purpose. The study examined the relationships between self-efficacy and physical activity in adolescent and parent dyads.
Design and Methods. A cross-sectional, correlational design was used to explore the relationships among levels of parent physical activity, parent–adolescent self-efficacy, and adolescent physical activity. Descriptive and multivariate regression analyses were conducted in a purposive sample of 94 adolescent/parent dyads.
Results. Regression results indicated the overall model significantly predicted adolescent physical activity (R2= .20, R2adj= .14, F[5, 70]= 3.28, p= .01). Only one of the five predictor variables significantly contributed to the model. Higher levels of adolescent self-efficacy was positively related to greater levels of adolescent physical activity (β= .29, p= .01).
Practice Implications. Practitioners are encouraged to examine the level of self-efficacy and physical activity in families in an effort to develop strategies that impact these areas and ultimately to mediate obesity-related challenges in families seeking care.
