A Structural Equation Model of Quality of Life in Adults with Type 2 Diabetes in Korea

PurposeThe purpose of this study was to test a structural equation model in which self-efficacy and self-care activity predicts the quality of life (QOL) of individuals with type 2 diabetes in Korea.MethodA survey about self-care activity, self-efficacy, glucose control, and QOL was completed by 132 diabetic patients from public health centers in Korea. Data were analyzed using SPSSWIN 18.0 and AMOS 19.0.ResultsThe mean age of the participants was 63.2 years. The proposed model was a good fit for the data based on the model fit indices. Self-efficacy had a significant effect on self-care activity (95%), and this model explained 25% of the variance in QOL.ConclusionsThe findings indicate that self-efficacy and self-care activity play important roles in explaining QOL in adults with type 2 diabetes. Nursing strategies to increase QOL in this population should contain self-efficacy enhancement to promote the performance of self-care activity.
