Background: There have been very limited prospective studies examining social-cognitive models within stages of behavior change in the exercise domain.Purpose: We examined the utility of the theory of planned behavior (TPB), incorporating self-identity and descriptive norm constructs, to predict exercise behavior across the stages of change, in individuals with type 2 diabetes.Methods: Data were obtained from a longitudinal study. Multi-group structural equation modeling was used to estimate the association between extended TPB constructs and exercise within different stages groups.Results: 647 individuals completed a self-report questionnaire at baseline and at 3 months follow-up. The extended TPB model explained 8–15% variance of exercise behavior and 42–81% variance of exercise intention within three stages groups in the cross-sectional design. The extended TPB model explained 4%-13% variance of exercise behavior and 42–66% variance of exercise intention in the longitudinal design. Intention was significantly related to exercise behavior in the pre-action and action stages. Self-identity, perceived behavioral control and descriptive norms were stronger predictors of intention in different stages.Conclusion: Discontinuity patterns in the extended theory of planned behavior for the different stages groups were found. Intention was a significant predictor of exercise in the pre-action and action stages at 3 months.

The theory of planned behavior (TPB) and stages of change (SOC) models have been used to predict physical activity (PA) in people with disabilities. The purpose of this chapter is to give an overview of the TPB and SOC models and the research findings stemming from testing them in people with impairments. The health action process approach (HAPA), designed with individuals with disabilities, is also introduced, along with suggested future research using the HAPA. The HAPA is in many ways a meta-theory, as it incorporates many constructs from theories discussed here and in other chapters. For instance, various forms of self-efficacy, outcome expectations, coping, planning, and social support are all included in the HAPA. In addition, the HAPA includes a three-stage model in which people are labeled as pre-intenders, intenders, or actors. Researchers intending to use the SOC theories and the TPB should know that they have come under criticism, and these criticisms are addressed in the chapter.
