Objective: This study aimed to investigate the effectiveness of cognitive behavioral stress management (CBSM) on health-related quality of life (HRQOL), self-efficacy of diabetes management, and adherence to treatment of patients with type ۲ diabetes. Materials and Methods: The present study was a semi-experimental study with a control group. The research samples included ۳۰ patients with type ۲ diabetes. Data collection tools in this study included the Boyer & Earp quality of life (QOL) scale for patients with diabetes (D-۳۹), the diabetes management self-efficacy scale (DMSES), and treatment adherence questionnaire in patients with chronic diseases. The CBSM therapy was performed in ۸ sessions for the experimental group. To analyze the data, a univariate analysis of covariance was used with SPSS-۲۳ software. Results: The results showed that the CBSM had a significant effect on the overall health-based QOL (F=۸.۶۲۰; P=۰.۰۰۷), diabetes management self-ffficacy (F=۱۲.۰۲۱; P=۰.۰۰۲), and treatment adherence (F=۸۳.۲۵۳; P=۰.۰۰۰۱). In addition, the CBSM has a significant effect on diabetes control (F=۸.۹۳۲; P=۰.۰۰۷), anxiety and worry (F=۵.۰۲۳; P=۰.۰۳۵), and sexual functioning (F=۷.۶۱۱; P=۰.۰۱۱), diet (F=۱۰.۰۴۱; P=۰.۰۰۴), therapeutic regimen (F=۲۴.۲۵۰; P=۰.۰۰۰۱), making effort for treatment (F=۲۲.۹۸۷; P=۰.۰۰۰۱), intention to take the treatment (F=۱۰۸.۰۰۱; P=۰.۰۰۰۱), adaptability (F=۲۸.۷۰۴; P=۰.۰۰۰۱), and integrating illness into life (F=۳۸.۲۶۳; P=۰.۰۰۰۱). Conclusion: The CBSM intervention can be used to improve health-based QOL, diabetes management self-efficacy, and treatment adherence in type ۲ diabetes patients.
