The effect of intrinsic motivation on self-efficacy and quality of life for low vision patients

Abstract

Objective To investigate the effect of self-management program on low vision patients and the role of intrinsic motivation. Methods A total of 160 low vision patients were assigned into 2 groups by random digits table method with 80 cases each. The control group was given routine doctor's advice and health education,and the observation group was given a self-management program guided by well trained medical personnel on the basis of the control group.The General Self-efficacy Scale (GSS) and Chinese-version Low Vision Quality Of Life questionnaire (CLVQOL) was conducted before and after intervention. The patients' intrinsic motivation also was evaluated by Intrinsic Motivation Inventory (IMI) after intervention. Results The total score and scores of interest/fun, inner selectivity, subjective ability and stress/strain dimensions of IMI were (62.25±3.74), (18.43±3.67), (16.13±1.53), (16.05±7.34), (11.64±2.74) points、in observation group and(50.24±4.32), (13.53±2.78), (13.67±1.75), (13.52±2.42), (9.52±1.77) points in control group, and there were significant differences (t=5.813-18.800,P <0.05). The scores of GSS and CLVQOL in observation group after intervention were (27.49±3.41), (64.30±7.04) points, which were higher than those in control group:(16.54±2.25), (34.86±3.99) points, and there were significant differences (t=23.973, 32.540,P <0.05). After intervention,the total score and interest/fun, inner selectivity, subjective ability and stress/strain dimensions of IMI in observation group were positively associated with the score of GSS(r =0.663-0.739,P <0.05). The total score of IMI was positively associated with the total score of CLVQOL(r=0.765,P <0.05). In addition, a positive association was observed between the total score and each dimension of CLVQOL and inner selectivity, subjective ability and stress/strain dimensions of the IMI(r=0.661-0.765,P <0.05). Conclusions A self -management program can improve low vision patients' self-efficacy and quality of life, intrinsic motivation is the important factor influencing the effect of self-management program.
