title: The effect of diabetes knowledge and attitudes on self-management and quality of life among people with type 2 diabetes.
abstract: We examined the effect of diabetes knowledge and attitudes on self-management and quality of life (QoL) of people with type 2 diabetes mellitus (T2DM). We employed a cross-sectional study design. A total of 137 female and 129 male participants with T2DM completed the diabetes knowledge scale (DKN), Diabetes Integration Scale-19 (ATT19), Summary of Diabetes Self-care Activities (SDSCA) scale, and Diabetes Quality of Life (DQoL) scale, measuring diabetes knowledge, attitudes, self-management, and QoL respectively. The SDSCA scale measures diet, exercise, blood glucose monitoring, and foot care. The DQoL scale measures satisfaction and impact of QoL. An initial path model that tested the inter-relationships of the study variables was first identified based on previous research. Then, the path model was tested using Mplus 7.3. In the final model, diabetes knowledge was a significant predictor of attitudes and self-management in terms of blood glucose monitoring and foot care. Attitudes was a significant predictor of impact of QoL. Self-management in terms of blood glucose monitoring was a significant predictor of impact of QoL and diet was a significant predictor of satisfaction and impact of QoL. Exercise and foot care aspects of Self-management were significant predictors of satisfaction and impact of QoL respectively. The final model showed a good fit to the data: RMSEA = .045 (90% CI: .009, .071; Clfit = .601), CFI = .950, SRMR = .058. The findings suggest a theoretical basis to direct the development of appropriate health programs and interventions for improving QoL in people with T2DM and warrant replication in diverse samples.
