| Abstract: | The present study examined the social-cognitive predictors of exercise intention among substance abusers in recovery. An extended version of the theory of planned behavior was used, accounting for past exercise behavior and self-esteem. Members of self-help groups in Melbourne, Australia (N = 201) completed an anonymous questionnaire. Hierarchical regression, multiple mediation, and moderation analysis were used. The findings showed that attitudes and perceived behavioral control were the strongest predictors of exercise intentions, and mediated the effects of past behavior and self-esteem. Psychological interventions to promote exercise among substance abusers should target attitudinal beliefs and build self-control skills. |
