Developing a Valid and Reliable Coping Self-Efficacy Scale (CSES) among Patients with Type 2 Diabetes: Iranian Version


Introduction: This study aimed to develop valid and reliable scale with the intention of measure Coping Self-efficacy (CSES) of Iranian type 2 diabetic patients. Patients and Methods: Validity and reliability of Iranian version of Coping Self-efficacy Scale (CSES) were measured by a cross-sectional study. Content validity, reliability and cultural equivalency were appraised through qualitative and quantitative study on 260 participants who have type 2 diabetes. Results: Reliability and validity of the scale and its four subscales, such as “stop unpleasant emotions and thoughts” (a = 0.92) “used problem-focused coping” (a = 0.71), Self-efficacy on diabetes problem solving (a = 0.74) and “get support from friends and family” (a = 0.67) were approved explicitly by a psychometric analysis; these show that the scale was slightly valid and reliable on the study setting. An intraclass correlation coefficient was satisfactory (p < 0.001). Criterion validity between total scale and metabolic control Index (HbA1c) of type 2 diabetic patients was significant (p < 0.001) and showed indirect correlation with the domains of the scale. Conclusion: Study findings supported the reliability and validity of the Iranian version of new Coping Self-efficacy-24 for measuring Coping Selfefficacy among Iranian type 2 diabetic patients. Based on our finding, we would like to recommend appropriate interventions in the future.
