Abstract
The purposes of this study were to examine the predictions of social norms and self-efficacy on adolescents'
physical activity and investigate whether self-efficacy mediates the relationship between adolescents’ social
norms and physical activities. Participants included 488 students enrolled in 7th to 12th grade (Male: 255,
Female: 233, Mage = 15.13, SD = ± 1.56). Three Korean-version questionnaires were used to explore a
possible association between self-efficacy and social norms and physical activity among adolescents. Data
were analyzed using by crosstab analysis, correlation analysis and multiple regression analysis. Results
indicated that only peer norms predicted physical activity rather parents or teachers’ norm. Further, both self
efficacy and social norms predicted physical activity, but self-efficacy accounted more variance. Moreover,
both males and females’ self-efficacy fully mediated the relationship between peer norms and physical
activity. The findings suggested that when initiating an exercise program for adolescents’ health and fitness
practitioners should foster self-efficacy and peer norms as motivational strategies to increase physical activity.
