OBJECTIVE: To evaluate the efficacy of a self-regulation (SR) weight reduction intervention on weight, body mass index (BMI), glycosylated hemoglobin (HbA1c) (primary outcomes), exercise, nutrition and quality of life (secondary outcomes). METHODS: A pilot intervention (n=53) based on SR-principles consisted of a motivational interview, group sessions and a workbook and was evaluated against standard care with (n=38) and without a self-help manual (n=38). Subjects were overweight (BMI>27) patients with type 2 diabetes (52% female) from a Dutch hospital (mean age 58.14, S.D.=8.86). RESULTS: No differences in the outcomes were found between the intervention and control groups at 3 (T2) or 6 (T3) months. However, results at T2 and T3 revealed that patients with higher SR-skills scores had lower HbA1c levels than patients with lower scores. CONCLUSION: The SR-intervention did not significantly influence the outcomes. This apparent lack of effect might, however, partly be due to high attrition rates in all treatment groups. SR-skills were positively related to changes in HbA1c-levels. PRACTICE IMPLICATIONS: Improving SR-skills of overweight diabetes type 2 patients may improve their glycemic control. Patients who are 'external regulators' may however profit more from directive than from SR-interventions.
