The impact of a stage-matched intervention to promote exercise behavior in participants with type 2 diabetes.

This study was designed to develop and evaluate a stage-matched intervention (SMI) in Korean participants with type 2 Diabetes. The SMI was based on main constructs derived from the Transtheoretical Model match to the individual's stages of readiness for exercise behavior. The SMI was developed according to the results of the content validity tested by an expert group (n = 9). A control group pre- and post-test design was used for evaluating the impact of the SMI: the intervention group (n = 22) participated in the SMI for 3 months, while the control group (n = 23) received usual educational advice. The intervention group, compared to the control group, showed significant improvements in stages of change for exercise behavior (p < 0.001), physical activity levels (p < 0.001), and reductions in FBS (p < 0.05) and HbA(1)c (p < 0.05). This study yielded evidence for the beneficial impact of the SMI in participants with type 2 Diabetes.
