The purposes of the study were to predict stages of change in adolescent exercise behavior, to explore the differences in decision balance and self-efficacy by stages of change, and to present the possible relationship model between stages of change, decision balance and self-efficacy. A total of 671 adolescents randomly selected from junior high and high schools in Nowon-gu district in Seoul were surveyed. Three Korean-version instruments were used to identify exercise stages of change and their relationship with exercise benefits/barriers and self-efficacy of adolescents: Stages of Change Scale for Exercise, Decision Balance for Exercise, and Self-efficacy Scale. Results indicated that of 671 adolescents 54.5% do not exercise or exercise irregularly (Precontemplation 17.5%, Contemplation 16.6% and Preparation 20.4%). Male adolescents were more likely to be in the maintenance stage, whereas females were more likely to be in the contemplation stage. The Self-efficacy scores of adolescents increased with advancing of exercise stages and were statistically significant differences between the exercise stages. In decision balance adolescents` exercise benefits and barriers were also substantially differences by each exercise stages. In addition, the results revealed that stages of exercise behavior were significantly correlated with self-efficacy, exercise benefits and exercise barriers. On the basis of these correlations, this study identified that self-efficacy, exercise benefits and exercise barriers were the significant variables to explain a possible relationship with exercise stages of adolescents. This study provides significant and new information about relatively unstudied Korean adolescents and has the potential to influence the development of better health promotion and exercise intervention for Korean adolescents in a school and community level.
