Abstract

Introduction: Obsessive compulsive disorder is the fourth prevalent psychiatric disorder, which has caused so much debate regarding its categorization in diagnostic systems, due to its specific and complicated nature. However, its behavioral and biological aspects have not been clearly specified.
Method: In order to study the relationship between temperament, character aspects and neuro-behavioral system, 288 students completed TCI-125, GW-120, and Padua obsessive compulsive inventory. Data were analyzed by multiple regression method.
Results: Findings indicated that there were significant correlations between novelty seeking, harm avoidance, persistence, as well as cooperativeness, self-directiveness dimensions of character, behavior inhibition system and behavioral activational system and OCD symptoms. Also, harm avoidance, novelty seeking dimensions of temperament and cooperativeness, self-directedness of dimensions of character as well as behavioral inhibition system could predict different symptoms of OCD.
Discussion: Regarding the role of temperament character and behavioral systems in predicting OCD symptoms, it could be suggested that OCD has neurobiological basis.
