Abstract

The Disgust Scale (DS; Haidt, McCauley, & Rozin, 1994) is the most widely used instrument for assessing disgust propensity (i.e., individual tendency to experience disgust). Yet, psychometric evaluations of the DS are scarce while the literature shows that the reliability of its subscales are unacceptably low. Recently, it was suggested to reduce the number of subscales (Olatunji, Sawchuk, de Jong, & Lohr, 2007a). This study is a first exploration of this reduced three-factor solution in an independent sample. In study I, we examined whether a three-factor solution improves psychometric properties of the DS. Students from Maastricht University (N =535) and the University of Groningen (N =432) completed the DS. In study II, the DS was revised by dropping redundant items and revising its scoring format. The DS-R was administered to students from the University of Groningen (N =472) and Ghent University (N =41) to study its psychometric properties. The revisions improved the psychometric features of the DS, and showed that the DS-R is a valid and reliable index to establish core disgust, animal-reminder disgust, and contamination.
