Beliefs of blue-collar workers: stage of readiness for exercise.

OBJECTIVE To address a theoretical debate regarding contributions of self-efficacy and the theory of planned behavior (TPB) in explaining the amount of variance in stage of readiness to exercise among blue-collar workers. METHOD A validated questionnaire was used for assessment. RESULTS LISREL indicated that self-efficacy had the most influence on stage and TPB constructs were subjugated to self-efficacy. Univariate analyses indicated that self-efficacy and TPB variables are important for intervention. CONCLUSIONS Self-efficacy plays a major role in explaining exercise stage among high-risk blue-collar workers, and self-efficacy and TPB constructs are important to consider in designing interventions.
