The Disgust Scale has been designed to measure disgust propensity-the individual ease in experiencing disgust. The present study aimed to explore the validity, reliability, the factor structure, and the measurement invariance of the Greek version of the Disgust Scale-Revised (DS-R). A sample of 754 healthy participants completed the Greek version of the DS-R. A subset ( = 363) also completed the revised Symptom checked list and the Eysenck Personality Questionnaire, in order to examine the concurrent validity. Exploratory and Confirmatory factor analyses in different subsets were used to examine the factor structure. Multiple indicators-multiple causes model (MIMIC) models were used to assess the measurement invariance across gender and age. Demographic influences were assessed using -tests, ANOVA, and Pearson's correlations. Exploratory factor analysis concluded to two and three factor models, with a factor structure similar to the ones proposed in the literature. Confirmatory factor analysis and bi-factor analysis provided evidence in favor of the three-factor solution. Measurement invariance test revealed differences in six items across gender, and three items across age. The psychometric properties of the factors were satisfactory. Demographic influences on the responses were present, especially with respect to gender. The Greek version of the DS-R demonstrated satisfactory psychometric properties, making it suitable for use for the Greek population.
厌恶量表旨在测量厌恶倾向，即个体体验厌恶情绪的难易程度。本研究旨在探讨修订版厌恶量表（DS-R）希腊语版本的效度、信度、因子结构和测量不变性。754名健康参与者完成了DS-R希腊语版本的测试。其中一个子集（n = 363）还完成了修订后的症状检查表和艾森克人格问卷，以检验其同时效度。对不同子集进行探索性和验证性因素分析，以检验因子结构。使用多指标-多原因模型（MIMIC）评估性别和年龄之间的测量不变性。使用t检验、方差分析和皮尔逊相关性评估人口统计学影响。探索性因素分析得出了二因素和三因素模型，其因子结构与文献中提出的结构相似。验证性因素分析和双因素分析为三因素解决方案提供了支持证据。测量不变性测试显示，六个项目在性别上存在差异，三个项目在年龄上存在差异。各因子的心理测量特性令人满意。人口统计学对回答有影响，尤其是在性别方面。DS-R希腊语版本表现出令人满意的心理测量特性，适用于希腊人群。
