Development of the Diabetes Self-Care Efficacy Scale

The present study elaborates the conceptualization and process of development of a scale for assessing diabetes self-care efficacy (DSCE) in patients of diabetes, type 1 and type 2. Health maintenance in chronic illness as diabetes is dependent on performing several key self-care behaviours. The present study discusses two parts—Part I elaborates the qualitative exploration of the research construct through semi-structured interview of diabetic patients. It included 25 diabetic patients, Type-I (n?=?5) and Type-II (n?=?20). Part II discusses the quantitative research methods. The sample consisted of 233 diabetic patients, Type-1 (n?=?39) and Type-2 (n?=?194), who were randomly selected from diabetes and endocrine outpatient department (OPD) of a hospital in, Kolkata, India. Following an exploratory approach employing Principal Component Analysis (PCA), three components were yielded that accounted for approximately 60% of explained variance. Cronbach’s alpha was established at 0.89 indicating satisfactory internal reliability. The components were identified as component 1, “Beliefs about physical exercise regimen” (BPE), component 2, “Beliefs about food and insulin administration and medication recommendations” (FMR) and component 3, “Beliefs about learning and following from others” (LFO). To test the obtained factor structure of the proposed DSCE scale, a confirmatory analysis was performed to help validate the 3-factor, 15-item DSCE scale. The scale is first one of its kind to be proposed and developed in an Indian diabetes context and can prove useful in other settings. Study findings have implications for use in hospital setup and for development of intervention programs in dealing with diabetes patient population.
