Objective: This study evaluated the effectiveness of a Participatory Empowerment Group (PEG) for Chinese type 2 diabetes patients in Shanghai. Method: A randomized waiting list control and pretest and posttest comparisons were used to evaluate the effectiveness of the intervention by comparing blood sugar level and health-related quality of life. Results: Before the intervention, scores on both blood sugar and quality of life did not differ significantly between the experimental and control groups. After the intervention, participants in the experimental group scored higher on quality of life and lower on blood sugar level compared to the control group. Conclusions: The PEG was effective in enhancing the quality of life of Chinese type 2 diabetes patients. (Contains 3 tables.)
