Adaptation and psychometric properties of the Disgust Scale Revised in a peruvian sample

The present study sought to adapt and validate the psychometric properties of the Disgust Scale Revised in Peruvian Adults. A non-probabilistic, snowball sample of 335 Peruvian adults was taken. For content validity, the clarity of the items were evaluated using Aiken's V. For internal structure validity, the fit indices of a series of confirmatory factor analyzes were evaluated for the one, two, and three-factor models. For validity with respect to other constructs, the SD-R constructs were correlated with the purity/sanctity subconstruct of the Moral Foundations Questionnaire. For reliability, the ordinal alpha and the omega coefficient were used. Acceptable fit indices were obtained for the two and three oblique factor models, acceptable reliability indices for the core disgust and animal reminder scales was obtained, and small and significant positive correlations were obtained between the contamination and animal reminder factors with the purity/sanctity scale of the MFQ. The DS-R is an instrument with acceptable psychometric properties, although some adjustments must be made related to the reliability of the contamination scale, added to the exploration of other variables that correlate to each of its constructs to obtain greater validity in relation to other variables.
