This study aimed to investigate the relationships among perceived risk, self-efficacy, self-care activities, and HbA1c in adult patients with type 2 diabetes. The study was designed as a descriptive study. A questionnaire was administered to a sample of 180 patients who visited a clinic at a tertiary hospital in Seoul. Multiple regression analysis and quantile regression analysis were performed on the data using SPSS 23.0 and Stata 15.0 programs. Age, perceived risk, and self-efficacy were identified as factors affecting self-care activities. For quantiles under 25%, age was significant, and for quantiles over 75%, perceived risk was significant. For factors influencing HbA1c, duration of diabetes, pharmacological treatment, awareness of own HbA1c level, and perceived risk were identified. Awareness of own HbA1c level and perceived risk were significant for quantiles over 75%, and pharmacological treatment was significant for quantiles under 25%.
