Effect of motivational interviewing on the medication adherence and self-efficacy in patients with ulcerative colitis

Objective To evaluate the effect of motivational interviewing (MI) on the medication adherence and self-efficacy in patients with ulcerative colitis. Methods Totally 81 patients with ulcerative colitis were randomly divided into the control group (n=40) and the experimental group (n=41) . The patients in the control group received routine ulcerative colitis education, while the patients in the experimental group received developed motivational interviewing intervention. The problems existing in treatment course were found out through interview and protocols were made with patients together. Results One and three months after the intervention, the scores of medication adherence in the experimental group were (7.20±0.85) and (6.57±1.02) , higher than those of the control group (6.48±0.71) and (5.98±0.85) ,t=3.868, 2.655, both P<0.05. Self-efficacy scored higher in the experimental group than that of the control group,(229.73±14.61) vs.(213.60±13.06) ,t=5.233,P <0.01. Conclusions Motivational interviewing is much more effective than routine education on the improvement of medication adherence and self-efficacy in patients with ulcerative colitis.
