OBJECTIVES: To investigate the utility of the protection motivation theory (PMT) for explaining physical activity (PA) in an adult population with type 1 diabetes (T1D) and type 2 diabetes (T2D). DESIGN: Cross-sectional and 6-month longitudinal analysis using PMT. METHODS: Two thousand three hundred and eleven individuals with T1D (N=697) and T2D (N=1,614) completed self-report PMT constructs of vulnerability, severity, response efficacy, self-efficacy, and intention, and PA behaviour at baseline and 6-month follow-up. Multi-group structural equation modelling was conducted to: (1) test the fit of the PMT structure; (2) determine the similarities and differences in the PMT structure between the two types of diabetes; and (3) examine the explained variance and compare the strength of association of the PMT constructs in predicting PA intention and behaviour. RESULTS: The findings provide evidence for the utility of the PMT in both diabetes samples (chi(2)/df=1.27-4.08, RMSEA=.02-.05). Self-efficacy was a stronger predictor of intention (beta=0.64-0.68) than response efficacy (beta=0.14-0.16) in individuals with T1D or T2D. Severity was significantly related to intention (beta=0.06) in T2D individuals only, whereas vulnerability was not significantly related to intention or PA behaviour. Self-efficacy (beta's=0.20-0.28) and intention (beta's=0.12-0.30) were significantly associated with PA behaviour. CONCLUSIONS: Promotion of PA behaviour should primarily target self-efficacy to form intentions and to change behaviour. In addition, for individuals with T2D, severity information should be incorporated into PA intervention materials in this population.
