Effect of motivational interviewing on selfmanagement in patients with type 2 diabetes mellitus: A meta-analysis

摘要

Objective:The objective of this meta-analysis was to evaluate the effect of motivational interviewing(MI)on self-management in patients with type 2 diabetes.Methods:Randomised controlled trials that assessed the effects of MI on self-management and HbA1c levels in patients with type 2 diabetes were systematically reviewed using multiple electronic databases.Weighted mean differences with 95%confidence intervals were calculated for continuous data.Results:Ten trials were included in this meta-analysis.The self-management ability of patients with type 2 diabetes who underwent MI was significantly better than that of patients in the control group(WMD,2.37;95%CI,1.77e2.98;p6 months)(p>0.05).Conclusions:MI was associated with improved self-management abilities among patients with type 2 diabetes,and short-term MI(6 months)effectively decreased the HbA1c level.The effect of long-term MI(>6 months)on the HbA1c level remains uncertain.Large-scale,higher-quality randomised controlled trials are needed to confirm the present findings.
