BACKGROUND
Type 2 diabetes is a serious and growing problem in Taiwan where it is the fifth leading cause of death, and health care costs are 4.3 times higher than for people without diabetes.
OBJECTIVES
The purpose of this study was to determine whether participation in a motivational interview for people with type 2 diabetes would improve their self-management, psychological and glycemic outcomes.
DESIGN
A randomized controlled trial to assess the effects of the motivational interviewing intervention.
SETTINGS
Participants were drawn from the diabetes outpatient clinic of a large teaching hospital in South Taiwan.
PARTICIPANTS
A sample of 250 type 2 diabetes people.
METHODS
Type 2 diabetes people were randomly allocated into either the motivational interview group or the usual care group from baseline to 3months follow-up. The intervention was based on motivational interviewing which encompassed a variety of interviewing techniques, and reflected each person's readiness stage to change. The control group was provided with usual care by nursing staff.
RESULTS
A total of 250 type 2 diabetic participants were randomized. The retention rate in the intervention group was 83% (n=104). The motivational interview did improve participants significantly in self-management, self-efficacy, quality of life, and HbA1c among diabetes people with appropriate baseline value (<121.24, <174.57, <107.18, and >7.62, respectively) but not in depression, anxiety and stress (F=0.13, p=0.72) compared to the control group at 3months follow-up.
CONCLUSION
The findings provided important evidence concerning the positive effect of motivational interventions in self-management, psychological and glycemic outcomes. This research provided evidence for future clinical practices in diabetes care.
