Description
Summary:To undertake the cultural adaptation and the psychometric assessment of the Summary of Diabetes Self-Care Activities measure (SDSCA) in Spanish population with type 2 diabetes mellitus. Clinimetric validation study. Primary health care centers of District Malaga and Valle del Guadalhorce. Three hundred thirty-one persons with type 2 diabetes mellitus. The SDSCA validated in mexican population was subjected to semantic and content equivalence using a Delphi method, its legibility was determined by INFLESZ scale. Subsequently psychometric validation was conducted through exploratory and confirmatory factor analysis (herein after EFA and CFA), internal consistency, test-retest reliability and discriminant validity. Two rounds were needed to achieve the consensus in between the panel members. Then, the index provided a good readability. The EFA suggested a model with 3 factors (diet, exercise and self-analysis) with 7 items which explained 79.16% variance. The results of CFA showed a good fit of SDSCA-Sp. The Internal consistency was moderate to low (α-Cronbach =0.62) and test-retest reliability was evaluated in 198 patients (t=0.462-0.796, p
