Objective: Mental contamination has been conceptualized as the feelings of internal dirtiness in the absence of the actual contact with a dirty physical object or a person. Mental contamination is considered to play an important role in the maintenance and persistence of the obsessive compulsive disorder (OCD). This study aimed to examine the psychometric properties of the Turkish version of two objective measures of mental contamination. These are Vancouver Obsessive Compulsive Inventory-Mental Contamination Scale (VOCI-MC) and Thought-Action Fusion-Contamination Scale (TAF-CS). Method: The participants were 255 university students (183 female and 70 male) with an age range of 18-28. The participants were asked to fill out the questionnaire set consisted of VOCI-MC, TAF-CS, Thought-Action Fusion Scale (TAFS), Disgust Scale-Revised, Trait Anger Expression Inventory and Obsessive Compulsive Inventory-Revised (OCI-R). Results: Reliability analyses indicated that the internal consistency of VOCI-MC and TAF-CS was .93 and .92, and test-retest reliabilities were .79 and .6, respectively. Consistent with the original study, the results of the explanatory and confirmatory factor analysis indicated that both scales have one factor structure. Convergent and divergent validity analyses revealed that both scales were positively correlated with OCI-R total scores and its subscales as well as TAF total score and its subscales; and while this relationship was significantly less strong for Trait Anger and Disgust Sensitivity. While VOCI-MC significantly predicts OCD symptomatology, TAF-CS is observed to have no predictive power in this regard. Conclusions: The results support that the psychometric properties of the Turkish versions of the scales meet the acceptable standards for validity and reliability and therefore can be used among Turkish population.
