The purpose of the study was to predict obsessive-compulsive disorder based on parenting styles, locus of control and perceived social support in university students. Research method was descriptive and correlational. For this purpose, from among Female university students at Bachelor's degree in Islamic Azad University, borujerd branch, that were 4576 people, 113 Female, were selected with non-randomly available sampling method. Participants completed Maudsley Obsessional-Compulsive Inventory (1977); Baum rind’s (1972) parenting style questionnaire; Rotter’s (1966) Locus of Control Scale and Zimet's et al (1988) Multidimensional Scale of Perceived Social Support. The data were analyzed with Pearson correlation and multiple regression and SPSS 20. The results showed that, there isn't significant relationship between components of parenting styles(authoritative, authoritarian and permissive), locus of control and components of perceived social support (family, friends and others) with OCD (r=0311, p=0.211). Also, regression analysis showed that predictive variables, predict only % 9.7 of the variance of obsessive-compulsive disorder. parenting styles, locus of control and perceived social support, are not strong predictors for obsessive-compulsive disorder. Therefore, in the study of obsessive-compulsive disorder, along with attention to them, other important variables should be considered.
