Abstract
Aim and Background: Some of Obsessive-Compulsive Disorder (OCD) patients believe that their unpleasant thoughts can influence the external events. The aim of this study was to investigate the correlation between the contents of thought-action fusion and obsessive-compulsive symptoms in patients with OCD. Methods and Materials: In this cross-sectional correlative study 60 OCD patients selected by available sampling method. Maudsley Obsessive-Compulsive Inventory (MOCI) and revised Thought-Action Fusion questionnaire (TAF-R) were administered. Collected data were analyzed using Pearson correlation and multiple regression analysis methods. Findings: There was positive and significant association between obsessive-compulsive symptoms and TAF-R subscales (P < 0.05). The result of stepwise regression indicate that, valence of negative events was strongest predictor of washing, likelihood of negative events was strongest predictor of checking, responsibility of positive events was strongest predictor of doubt, and likelihood-self was strongest predictor of obsessional thoughts. Conclusions: The results indicated positive and significant correlation between the TAF and OCD symptoms. Thus, it seems that occurrence of cognitive bias such as TAF increases the individual’s vulnerability to OCD.
Aim and Background: The purpose of this study was to compare executive function and sustained attention in students with obsessive–compulsive, high schizotypal and overlapping symptoms and a control group. Methods and Materials: The present study assessed undergraduate students of Tabriz University by ex post facto method. Randomized multi-stage cluster sampling was used to select 1570 students. The subjects completed Schizotypal Personality Questionnaire and the Obsessive-Compulsive Inventory-Revised. Then, during the screening phase, 140 students (in groups of 35) were selected. They completed Wisconsin Card Sorting Test, Continuous Performance Test and Stroop color-word test. Data was analyzed using descriptive statistics and ANOVA test. Findings: The results of this study showed a significant difference in executive function and sustained attention between high schizotypy and overlapping groups and the control group (P < 0.05). Except for commission errors in CPT, other differences observed between obsessive-compulsive and control groups in executive function and sustained attention except were insignificant (P > 0.05). Conclusions: The difference between the overlapping group and obsessive-compulsive and high schizotypy groups in terms of executive function and sustained attention pattern may indicate the unique clinical characteristics of the overlapping group.
