    The role of disgust proneness and contamination-related thought-action fusion in mental contamination-related washing urges
    (Springer, 2023) Inozu, Mujgan; Bilekli Bilger, İlgün; Trak, Ezgi
    Previous studies associated disgust proneness and thought-action fusion with mental contamination. The present study aims to investigate the associations among disgust propensity, disgust sensitivity, contamination-related thought-action fusion, mental contamination, and related factors, including internal/external negative emotions and washing urges. One hundred eighty female participants filled out the questionnaires assessing disgust proneness and contamination-related thought-action fusion and rated their baseline feeling of dirtiness and negative emotions. They listened to an audiotape instructing them to conceive themselves being subject to a nonconsensual kiss attempt by a male and rated their mental contamination, negative emotions, and the urge to wash levels. The path analysis indicated that disgust propensity and contamination-related thought-action fusion were significantly associated with disgust sensitivity. Their association with the urge to wash was positively mediated by mental contamination and negative emotions. This is the first study examining the above-mentioned cognitive and affective factors in a mediation model using a non-Western population. Our findings are crucial for understanding mental contamination and washing behavior.

    The use of virtual reality (VR) exposure for reducing contamination fear and disgust: Can VR be an effective alternative exposure technique to in vivo?
    (Elsevier, 2020) Inozu, Mujgan; Celikcan, Ufuk; Akin, Burcin; Mustafaoğlu Çiçek, Nuray
    Background and objectives: Virtual reality (VR) has become a new tool in psychological research and application. Although several studies have investigated its triggering and reducing role in anxiety via VR-based exposure and response prevention (VR-ERP) across different psychopathologies, its efficiency in contamination fear and reduction of disgust are yet to be examined. The study contributes to the field by investigating the effectiveness of the VR-ERP on the reduction of anxiety, disgust and urge to wash levels using an experimental design. Methods: A total of 21 non-clinical participants with high contamination fear were randomly assigned to experimental (n = 9) and control (n = 12) groups. The experimental group was exposed to repeated VR-ERP sessions. Results: After a minimum of three VR-ERP sessions, the experimental group scored significantly lower than the control group on the anxiety, disgust, and urge to wash hands scores. Limitations: A small sample size, an analogue sample, and a generic virtual scenario content were potential limitations of the study. Conclusions: The results indicated that the VR-ERP can be an efficient and alternative exposure tool in the reduction of anxiety, disgust, and urge to wash hands. The theoretical and clinical applications of the VR-ERP in the treatment of contamination-based OCD symptoms were discussed in light of our findings.
