title: Development and psychometric evaluation of the Diabetes Self-Efficacy Scale.
abstract: OBJECTIVE
  No scales measure self-efficacy in women with Type 2 diabetes. A scale was developed and tested.
  
  
  METHODS
  Items generated, content validity index (CVI) assessed by experts, the 2-part Diabetes Self-Efficacy Scale (DSLF-I and DSLF-II) was piloted with 62 women, administered to 208 women, and then readministered to 30 women to determine initial reliability. Factor analysis was conducted for construct validity. Discriminant, convergent, and predictive validity was examined.
  
  
  RESULTS
  The CVI index was 98%. Cronbach's alphas were 0.88 (DSLF-I) and 0.82 (DSLF-II; pilot) and 0.87 and 0.86, respectively (main study); test-retest correlation was .60 (DSLF-I) and .69 (DSLF-II). There were 3 factors that emerged: diabetes knowledge of self-care activity, diabetes diet self-care, and diabetes medication self-care.
  
  
  CONCLUSIONS
  The Diabetes Self-Efficacy Scale demonstrates good initial reliability and validity.
