Factor Analysis and Evaluation of Internal Structure of Disgust Sensitivity Scale

Disgust is basic emotion which associated with feelings of revulsion and withdrawal behaviors from dangerous situations. The aim of this study was to evaluate factor analysis of Persian version of Disgust Scale that was designed to measure individual's responses to various disgust-provoking situations.
300 individuals (185 boys and 115 girls) were selected by convenience sampling among students of Tabriz universities (Tabriz University,Payame Noor, Science and Research) and responded to Disgust Sensitivity Scale. Exploratory factor analysis with principal component analysis and varimax rotation,confirmatory factor analysis, Pearson correlation, T-test and multivariate variance analysis was used to analyze data.
Exploratory factor analysis identified four factorswith 25 questions. Central disgust, contamination disgust, animal reminder disgust and sex disgust were discovered factors. The internal consistency of these factors was 0.74, 0.50, 0.74 and 0.58 respectively.The findings revealed that women compared to men have more disgust sensitivity.Also the evaluation of four factor structure by confirmatory factor analysis showed that this model compared to original model of scale and revised three factors model version had better fitness.
Research findings suggest that the Persian version of Disgust Scale is appropriate tool to individual's measure disgust sensitivitytoward disgust-provoking situations.
