Abstract

Introduction: The goal of this study was to determine the psychometric characteristics of the Revised Self-Disgust Scale in Iranians.
Method: This study was basic research. The methodology employed was descriptive-correlative. The statistical population consisted of individuals who had been students at universities in Tabriz city from 2018 to 2019. A total of 392 individuals were randomly selected. The scale was translated by two English language experts, who made alterations based on feedback from psychology professors and 30 pilot test participants. The scale was then administered along with Beck’s Depression Scale, Disgust Sensitivity, and the OXFORD Happiness Questionnaire. To assess reliability, the scale was administered again after a 2-week interval. Data analysis was conducted using AMOS and SPSS-22.
Results: The scale has good face validity. Factor analysis confirmed two factors: behavioral (personality) and physical self-disgust. The instrument demonstrated significant convergent validity based on its correlation with the Beck Scale and the Disgust Scale (r = 0.32, 0.15, p < 0.01). Additionally, the correlation between the factors was 0.72, and between each factor and the total score was above 0.90. Finally, the results indicated that the internal consistency was 0.83. Test-retest reliability was high (r = 0.87, p < 0.01).
Discussion and Conclusion: It is inferred that the SDS-R demonstrates good validity and reliability among the Iranian population, making it suitable for measuring the self-disgust variable.
