ObjectiveThe study’s aim was to test prospective associations between information, motivation, and behavioral skills (IMB model) and self-care behaviors (diet, exercise, and blood glucose testing) among patients with type 2 diabetes.Methods295 participants were surveyed one (T1), six (T2), and 12 (T3) months after a diabetes course. Cross-lagged panel analyses were performed to test unidirectional and bidirectional relationships between IMB model variables and self-care behaviors.ResultsBlood-glucose testing at T1 was positively related to information at T2, which in turn was positively related to blood-glucose testing at T3. Controlled motivation at T1 was positively related to exercise at T2. Autonomous motivation at T2 was positively associated with exercise at T3. There was a positive bidirectional relationship across time between behavioral skills and general diet.ConclusionPatterns of prospective associations between IMB model variables and diabetes self-care depend on the self-care behavior considered. This model offers an interesting framework for examining how diabetes self-care behaviors evolve.Practice implicationsDiabetes education programs should provide information about current health status and promote experiential learning to help patients realize the impact of their behaviors on glycemic control, should foster autonomous motivation for long-term change, and should build on patients’ strengths and skills.
