The structure of disgust: domain specificity in relation to contamination ideation and excessive washing

The primary goal of the present study was to employ confirmatory factor analysis to compare two theoretical models regarding the factor structure of disgust (N = 307). The two-factor model of Animal Reminder and Core disgust proposed by Rozin et al. (2000) demonstrated superior model fit over a one-factor model that has been implicated in prior research. However, contrary to theoretical predictions, categorizing Hygiene disgust as Core disgust rather than Animal Reminder disgust provided an overall better fit for the two-factor model. The second aim of the study was to investigate the relationship between the empirically derived two-factor model and contamination ideation and excessive washing using structural equation modeling. Findings indicated that the Contamination Ideation and Excessive Washing latent factor was specifically related to Core disgust (domain specific) and negatively related to Animal Reminder disgust. The relevance of these findings in the context of future research investigating the role of disgust in specific anxiety disorders is discussed. (c) 2004 Elsevier Ltd. All rights reserved.
