Diabetes Self-Efficacy Scale (DASES)

The Diabetes Self-Efficacy Scale (DASES) is an 8-item self-report measure that assesses a patient's confidence in their ability to manage key diabetes self-care tasks: medication adherence, glucose monitoring, diet management, exercise, and coping with symptoms or complications. Developed by Lorig and colleagues based on social-cognitive theory, the DASES is grounded in Bandura's self-efficacy framework and demonstrates strong predictive validity for glycemic control, treatment adherence, and quality of life outcomes.
