The Study of the Relationship of Thought-Action Fusion, the Feelings of Responsibility and Guilt with Different Dimensions of Obsessive-Compulsive Disorder Symptoms in Shiraz University Students

This study represents an investigation of the Salkovskis and Rachman's theories concerning the obsessive-compulsive disorder (OCD). It seeks to determine the constructs of Thought-Action Fusion (TAF), feelings of responsibility and guilt that predict OCD original symptoms. To this end, 565 students of Shiraz University wereselected through random sampling. The participants in the study responded to "Thought-Action Fusion Scale", "PADUA Scale", "Responsibility Attitude Scale" and "Guilt Inventory".The results of stepwise multiple regression indicate that Thought- Action Fusion subscales are more predictive of the original obsessive-compulsive symptoms. Thus, moral component of this scale predicts OCD original symptoms more than other two constructs, i.e., the likelihood of realization of thoughts about self is the predictor of fear of guilt, and the likelihood of occurring negative events can be the predictor of obsessive checking and concerns losing motor behaviors.
