Propiedades psicométricas de la versión en español del Type 2 Diabetes Stigma Assessment Scale (DSAS 2) en población colombiana

INTRODUCTION: The perception of stigma has been negatively associated with the metabolic control and quality of life in patients with type 2 diabetes. The Diabetes Stigma Assessment Scale 2 (DSAS 2) was designed to specifically measure the stigma associated with this type of diabetes. However, the psychometric properties of its Spanish version have not yet been addressed. OBJECTIVE: To analyze the validity and reliability of the Spanish version of DSAS 2 in a Colombian population. MATERIALS AND METHODS: In total, 501 patients with type 2 diabetes from Barranquilla answered the Spanish version of DSAS 2, a questionnaire with sociodemographic and clinical indicators, as well as instruments to measure depression, self-efficacy, and stress. We performed a factor analysis (exploratory and confirmatory) to determine the internal structure of the DSAS 2 in Spanish and used the alpha coefficient (a) to evaluate its reliability. Additionally, we analyzed the relationship between the DSAS 2 scores and the other variables under study. RESULTS: The three-factor structure (different treatment / judgment, guilt and shame) showed good fit to the data (RMSEA = 0.081, CFI = 0.959, TLI = 0.95) and good reliability (α = 0.76). Significant correlations of the scores of the DSAS 2 Spanish version were observed with self-efficacy (r(s)=-0.37, p<0.001), stress (r(s) =0.24 , p<0.001), and depression (r(s)=0.1, p=0.021). Besides, the scores showed variations associated with sociodemographic and clinical variables. CONCLUSIONS: The Spanish version showed certain differences compared with the original version of the DSAS2 but there was adequate evidence of its validity and reliability to be used in Colombia.
