Effectiveness of motivational interviewing on improving Care for Patients with type 2 diabetes in China: A randomized controlled trial

Abstract

Background: To assess the effects of a motivational interviewing (MI)-based patient empowerment program (PEP) on type 2 diabetes mellitus (DM) patient self-management compared to traditional diabetes health education. Methods: Two hundred and twenty-five patients, recruited from community health centers (CHCs) and the family medicine clinic in the University of Hong Kong-Shenzhen Hospital in Shenzhen, were randomly assigned to the intervention or control groups. Patients in the intervention group (n = 117) received a four-session PEP in small groups over 1 month by trained nurses and doctors. The control group (n = 108) received the traditional lecture-style health education on DM. All the patients were followed up for 3 months. Outcomes included problem areas in diabetes (PAID) that measures diabetes-related emotional distress, patient enablement index (PEI), mental health, patient satisfaction respectively as well as lifestyle behaviors were assessed at baseline, post-activity and 3 months. Results: At post-intervention and the 3-month follow-up, the PAID score improved significantly in the intervention group (12.7 ± 13.6, 5.8 ± 7.6) compared to the control group (22.7 ± 22.8, 11.7 ± 14.6). No difference was found between groups for changes to exercise, diet, and medication adherence. The PEI score improved significantly at the 3-month follow-up in the MI group (7.27 ± 2.45 vs 5.81 ± 2.97). Conclusion: The PEP has a significant effect on improving diabetes-related distress, but MI was not significantly different from the traditional health education programs when it comes to the readiness to change.
