Abstract
The Three-Domain Disgust Scale (TDDS) contains three subscales assessing disgust sensitivity that may contribute to research on developing and maintaining psychopathology and treating psychopathologies related to disgust. This study aimed to adapt and evaluate the psychometric properties of the TDDS Turkish version. Two hundred and thirty-six participants responded to the scale consisting of 131 individuals with Obsessive Compulsive Disorder (OCD) and consisting of 105 non-clinical samples. Confirmatory Factor Analyses (CFAs) and multigroup CFAs were performed to evaluate the factor structure and the measurement invariance across clinically disordered TDDS. Reliability analyses were calculated with Cronbach’s alpha and a one-month retest. Besides, the convergent and discriminant validity of the TDDS were examined with the Beck Depression Inventory, Disgust Scale-Revised, Guilt Inventory, and State-Trait Anxiety Inventory. The study found that the three-factor structure of the TDDS was the best fit for the data, with high item-factor loadings, which proved invariant across clinically disordered. Convergent and discriminative validity of the TDDS was provided, and the reliability analysis results were satisfactory (all ≥ 0.70) in two samples. The TDDS presented high cross-language replicability and seemed an effective instrument for research in Turkish adults.
Keywords: disgust sensitivity, TDDS, validation, reliability, invariance.
