摘要

Purpose:The aim of this study was to evaluate the impact of motivational interviewing(MI)on the quality of life and its related factors in type 2 diabetes mellitus(T2DM)patients with poor long-term glycemic control.Design and methods:One hundred tenT2DMpatientswithpoor long-termglycemic control that were hospitalized in our institution were enrolled in this study and randomly assigned to receive eitherMI or routine diabetes education intervention.Patients''body mass index values,Homeostatic Model Assessment-Insulin Resistance(HOMA-IR)scores,and levels of glycated hemoglobin(HbA1C),triglycerides,high-and low-density lipoproteincholesterols,Summary of Diabetes Self-management Activities and Diabetes Specific Quality of Life assessments were recorded before and six months after intervention.Results:Baseline scores for all measurements did not differ between patients in the control and MI groups.Although MI resulted in a significant reduction of HbA1c and serum lipid levels compared with the baseline,the effect was not significantly different from the control intervention.However,the improvement in HOMA-IR scores was significantly greater in the MI group compared with the control intervention(2.8±2.8 vs.5.7±4.7;p=0.000).Moreover,MI significantly elevated diabetes self-management activities ratings compared with the control intervention(13.2±3.4 vs.10.9±4.3;p=0.004).Conclusion:Compared to routine diabetes education,MI is a more effective approach for improving HOMA-IR and self-management of T2DM patients with poor long-term glycemic control.
