Are the Symptom Dimensions in Obsessive Compulsive Disorder Related to Thought-Action Fusion, Magical Thinking, and Schizotypal Personality Traits?

INTRODUCTION

This study aimed to investigate the relationship between symptom dimensions within obsessive-compulsive disorder and thought-action fusion, magical thinking, and schizotypal personality traits.

METHODS

This research was designed as a cross-sectional case-control study. The study population involved patients with obsessive-compulsive disorder, and healthy controls who did not exhibit any psychiatric disorders following the Structured Clinical Interview for DSM-IV (SCID-I). Thought-Action Fusion Scale (TAFS), Magical Ideation Scale (MIS), Vancouver Obsessional-Compulsive Inventory (VOCI), Schizotypal Personality Questionnaire (SPQ), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) were administered to all participants. The two groups were compared in terms of sociodemographic variables and scale scores, Spearman's correlation analysis was performed to examine the relationship between TAFS total and all subscale scores, magical thinking, schizotypal personality traits and OCD symptom dimensions scores.

RESULTS

The study comprised 37 patients with OCD and 36 healthy controls. The patient group exhibited significantly higher scores in TAF total and all subscales, MIS, SCQ, BDI, and BAI, compared to the healthy control group. Positive correlations between magical ideation scores and VOCI-obsessions and VOCI-hoarding subscale scores and between schizotypal personality scores and VOCI-obsessions, VOCI-hoarding, VOCI-just right, VOCI indecisiveness scores was found.

CONCLUSIONS

The relationship between symptom dimensions in obsessive-compulsive disorder such as sexual, religious, aggression, hoarding, symmetry/ordering and magical thinking and schizotypal personality traits shows that these variables are among the determining factors for OCD symptoms. .
