Summary of Diabetes Self-care Activities: A confirmatory factor analytic approach.

Diabetes self-care activities is an important aspect for Type 2 Diabetes Mellitus (T2DM) patients. The aim of this study was to examine the construct validity of the Summary of Diabetes Self-Care Activities (SDSCA) measure. This was a cross-sectional study whereby T2DM patients were recruited from endocrine clinics in hospitals. The patients gave their informed consent before the interview. The SDSCA measure was used to gather information about the patients' diabetes self-care. Internal consistency reliability was measured by the Cronbach's Alpha value while the construct validity was measured by Confirmatory Factor Analysis. The fit indices for both the four-factor and five-factor structures were high (CFI >0.90 and GFI >0.90). The interconstruct correlations of the SDSCA scale was found to be highest between general and specific diet. The constructs of the SDSCA demonstrated adequate convergent validities. The SDSCA measure was found to be a valid one.
