effect of a nursing care program based on king’s theory of goal attainment on the self-efficacy of diabetic patients

Introduction: in managing diabetes, the self-efficacy of patients for self-care and adherence to treatment is important. one of the nursing theories that can lead to patients’ participation in care is king’s theory of goal attainment.objective: this study aims to investigate the effect of a nursing care program based on the theory of goal attainment on the self-efficacy of patients with diabetes.materials and methods: this quasi-experimental study was conducted on 60 patients with type 2 diabetes admitted to the endocrinology departments of two hospitals in tehran, iran. they were randomly assigned to two intervention (n=30) and control (n=30) groups. the data were collected using a sociodemographic/clinical form, the diabetes management self-efficacy scale (dmses), and the goal attainment scaling (gas). the intervention group received the nursing care program based on king’s theory. the self-efficacy of the patients was measured before, two weeks after (post-test), and two months after (follow-up) the intervention. chi-square, paired t-test, independent t-test, and repeated measures anova were used for data analysis.results: most of the participants were female (68%) and married (71%), and illiterate (30%) in the age group of 51-60 years (43%). before the intervention, the dmses score was 144.10±14.13 in the intervention group and 139.63±13.46 in the control group. two weeks after the intervention, the scores were 162.26±8.97 and 137.36±13.29, respectively. two months after the intervention, the scores were 166.5±8.16 and 136.96±11.8, respectively. there was a statistically significant difference in the two groups in the post-test and follow-up phases, compared to the pre-test phase (p=0.001). the difference was also significant between the two groups after intervention (p=0.001). according to repeated measures anova results, the effect of time (p=0.001, η2=0.438) and the interaction effect of time and group (p=0.001, η2=0.538) in the intervention and control groups were significant.conclusion: the nursing care program based on the theory of goal attainment can improve diabetic patients’ self-efficacy two weeks and two months after implementation. the theory of goal attainment can be used in care programs for diabetic patients.
