Abstract
By evaluating this research on the cognitive, emotional, and behavioral effects of mental contamination, this secondary study seeks to investigate the phenomena in people with obsessive compulsive disorder (OCD). A major factor in the onset and maintenance of OCD symptoms is mental contamination, which is defined as sensations of internal impurity or discomfort that frequently occur without physical contamination. With an emphasis on cognitive processes like guilt, shame, and disgust sensitivity, the study analyzes empirical data and theoretical models to investigate the connection between mental contamination and the intensity of OCD symptoms. It also investigates how certain obsessive habits, like washing and checking, are influenced by mental contamination. The study also investigates how disgust sensitivity may moderate the association between OCD symptoms and mental contamination. The results emphasize how crucial it is to incorporate mental contamination into OCD treatment frameworks and offer possible avenues for further study and clinical approaches targeted at enhancing treatment results.
