title: Reliability and Validity of the Revised Summary of Diabetes Self-Care Activities (SDSCA) for Malaysian Children and Adolescents.
abstract: BACKGROUND
  Self-care plays an important role in diabetes management. One of the instruments used to evaluate self-care in patients with diabetes is the Summary of Diabetes Self-Care Activities (SDSCA) questionnaire. A validated instrument in the Malay language is used to assess self-care practice among children and adolescents with diabetes in Malaysia.
  
  
  OBJECTIVE
  To translate and evaluate the psychometric properties of the revised version of the SDSCA questionnaire in the Malay language.
  
  
  METHODS
  Forward and backward translations were performed. An expert panel reviewed all versions for conceptual and content equivalence. The final version was administered to paediatric patients with diabetes between August 2006 and September 2007. Reliability was analysed using Cronbach's alpha and validity was assessed using exploratory factor analysis.
  
  
  RESULTS
  A total of 117 patients aged 10-18 years were enrolled from nine hospitals. The reliability of overall core items was 0.735 (with item 4) while the reliabilities of the four domains were in the range of 0.539-0.838. As core item number 4 was found to be problematic and it was subtituted by item 5a (from the expanded SDSCA) to suit local dietary education and practice; and the reliabilities of the overall core item (0.782) and the four domains (0.620 - 0.838) improved. Factor loadings of all the items were greater than 0.4, loaded into the original domains, and accounted for 73% of the total variance.
  
  
  CONCLUSIONS
  The Malay translation of the revised English SDSCA is reliable and valid as a guide for Malaysian children and adolescents suffering from diabetes.
