Περίληψη:
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 (n = 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 t-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.
