ABSTRACT
PURPOSE: The purpose of this study was to investigate associations between self-management and diabetes knowledge, diabetesrelated attitudes, family support, and self-efficacy in adolescents with type 1 diabetes mellitus based on the information-motivation- behavior skills model. METHODS: Data collection was conducted between March 18 and September 30, 2018. Patients (N=87) aged 12 to 19 years were recruited from the outpatient clinic of S children's hospital and an online community for patient with type 1 diabetes mellitus. Data were analyzed using descriptive statistics, the independent t-test, one-way ANOVA, Pearsons correlation, and hierarchical multiple linear regression with SPSS IBM 23.0, with the two-tailed level of significance set at 0.05. RESULTS: The mean score of self-management in adolescents with type 1 diabetes mellitus was 61.23±10.00 out of 80. The regression analysis showed that self-efficacy and family support significantly explained 56.9% of the variance in self-management (F=21.38, p<.001). Self-efficacy (β=.504, p<.001) and family support (β=.188, p<.001) were significant predictors of self-management. CONCLUSION: It is necessary to develop individual interventions to improve self-efficacy and family support for adolescents with type 1 diabetes mellitus to help them enhance their self-management.
