PURPOSE: To use the Transtheoretical Model (TTM) constructs to examine the most important physical activity stage of change predictors for mostly inactive adults with physical disabilities. METHODS: A cross-sectional survey completed on the Internet. One hundred fifty-one individuals with physical disabilities (50% response rate) completed the survey questionnaires. Self-report standardized measures were used. RESULTS: A direct discriminant function analysis revealed that the most important stage of change predictors were the behavioral (r2 = .88) and cognitive (r2 = .50) processes of change, followed by self-efficacy (r2 = .33) and decisional balance (r2 = .13). The most accurate stages in prediction were the contemplation (76.3%), preparation (58.3%), and precontemplation (40%) stages, whereas the least accurate stages were the action (0.0%) and maintenance (8.3%) stages. CONCLUSION: Health promoters and educators may use strategies from the TTM to develop theory-driven physical activity motivational programs for the posited populace. Considering the cross-sectional design, study replication is warranted.
