Schema and Locus of Control as Predictors of Obsessive Compulsive Disorder

Abstract

Objective: The study aimed to evaluate the correlation of maladjusted schema and locus of control with OCD, with the emphasis on cognitive approach to OCD.
Method: In this study, 273 Iranian participants were selected; of whom,30% were male and 70% were female. Participants’age ranged from 19 to 34 and the mean age for the sample was 23.42(SD=2.46). Participants completed questionnaire batteries including measure of Levenson Locus of Control, Young Schema Scale and Y –bocsOCD Scale. One sample consisted of patients with a primary OCD according to DSM-IV criteria. The other sample selected for this cross-sectional study was university students.
Result: Regression statistics item and reliability analysis were calculated with SPSS and LISREL software. Obsessive compulsive disorder was significantly predicted with both schema and powerful others’ locus of control, as these relations were large but association schema with OCDwas larger than the correlation OCD with powerful others (OCD with schema p.v<0.001 β=.47 and OCD with powerful others p.v<0.001 β=.15) .
Conclusion: The findings of the present study showed that schema and powerful others type of locus of control, were significantly related to both total OCD symptom severity and also to other sub scale of OCD. It is important to mention that schema can significantly predict all symptoms dimension of OCD. Furthermore, the analyses showed that schema was a strong predictor for obsessive thinking.
