Objective:
Previous studies have indicated that obsessive compulsive disorder (OCD) is associated with childhood traumatic experiences and higher levels of dissociation. Dissociative tendency may arise when individual attempt to incorporate adverse experiences into cognitive schema.
Methods:
We investigated the possible links among childhood trauma, dissociation, and cognitive processes. We evaluated 95 patients with OCD using the Beck Depression Inventory (BDI), Thought-Action Fusion Scale (TAFS), Metacognitions Questionnaire (MCQ-30), White Bear Suppression Inventory (WBSI), Dissociative Experiences Scale (DES), and Childhood Trauma Questionnaire (CTQ-28).
Results:
The CTQ-28 total scores were not associated with Y-BOCS total, Y-BOCS insight, BDI, TAFS, MCQ-30, and WBSI scores. The TAFS Total, MCQ-30, WBSI, and BDI scores were significantly associated with DES scores. Regression analysis revealed that MCQ-30 and WBSI scores significantly predicted the DES scores.
Conclusions:
These results suggest that in spite of pathological connotation of dissociative experiences, dissociation may primarily constitute a cognitive trait which is strongly associated with cognitive processes.
