AIM: To determine whether glycemic control is improved when motivational interviewing (MI), a patient-centered behavior change strategy, is used with diabetes self management education (DSME) as compared to DSME alone. METHODS: Poorly controlled type 2 diabetes (T2DM) patients (n = 234) were randomized into 4 groups: MI+DSME or DSME alone, with or without use of a computerized summary of patient self management barriers. We compared HbA1c changes between groups at 6 months and investigated mediators of HbA1c change. RESULTS: Study patients attended the majority of the four intervention visits (mean 3.4), but drop-out rate was high at follow-up research visits (35%). Multiple regression showed that groups receiving MI had a mean change in HbA1c that was significantly lower (less improved) than those not receiving MI (t = 2.10; p = 0.037). Mediators of HbA1c change for the total group were diabetes self-care behaviors and diabetes distress; no between-group differences were found. CONCLUSIONS: DSME improved blood glucose control, underlining its benefit for T2DM management. However, MI+DSME was less effective than DSME alone. Overall, weak support was found for the clinical utility of MI in the management of T2DM delivered by diabetes educators.
