Psychometric Properties of a Moroccan Version of the Summary of Diabetes Self-Care Activities Measure

Abstract

Background. The Summary of Diabetes Self-Care Activities (SDSCA) is a widely used self-report measure for diabetes self-management. It is an interesting tool for practice and research.Objectives. To translate and culturally adapt the SDSCA to the Moroccan context and to assess psychometric properties of the adapted version among type 2 diabetic patients.Methods. The Moroccan version was obtained following forward and backward translations. An expert panel issued a final version. The adapted version was administered to patients aged 30 years and older who have type 2 diabetes. Psychometric evaluation consisted of assessing validity through internal consistency (Cronbach’s alpha, item-to-scale and interitem correlations) and exploratory factor analysis and reproducibility (test-retest reliability).Results. Seventy-five participants were included. Cronbach’s alpha ranged from 0.20 (diet) to 0.99 (exercise). Moderate to good interitem and item-to-scale correlations were found. Factor analysis resulted in a Moroccan SDSCA version consisting of 8 items, organized in four subscales that explained 89.6% of the variance: diet, exercise, blood sugar testing, and foot-care. Intraclass correlations ranged from 0.27 to 0.52 for subscales.Conclusion. This study provides preliminary evidence for suitability of use of the Moroccan SDSCA among type 2 diabetic patients in order to assess diabetes self-management.
