Are self-management interventions suitable for all? Comparing obese versus nonobese type 2 diabetes patients.

OBJECTIVE: The aim of the current study was to compare obese and nonobese type 2 diabetes patients at baseline and after participating in an existing self-management intervention (i.e., Beyond Good Intentions) on cognitive, self-care, and behavioral measures to examine whether both groups are equally prepared and able to adopt self-management approaches.
METHODS: A total of 94 type 2 diabetes patients were included, of whom 64 (59% male) completed the study. The final sample consisted of 27 obese (33% male) and 37 nonobese (78% male) patients. The intervention comprised one individual and four group sessions and aimed to improve self-management behavior by enhancing proactive coping skills (i.e., setting concrete goals, identifying barriers, coping with difficult situations, action planning, and progress evaluation). Cognitive (i.e., proactive coping, self-control, self-efficacy), self-care (i.e., adherence to lifestyle recommendations), and behavioral (i.e., diet, exercise) measures were assessed at baseline and after completing the intervention.
RESULTS: At baseline, obese patients reported to possess lower cognitive skills and lower adherence to lifestyle recommendations compared with nonobese patients. The intervention was effective in improving cognitive skills, self-care activities, as well as dietary and exercise behaviors. Improvements were equal for obese and nonobese patients. However, obese patients were more likely to drop out.
CONCLUSIONS: Although obese type 2 diabetes patients were found to possess limited skills at baseline compared with nonobese patients, the self-management course proved to be equally effective for both groups.
