Development and validation a metacognitive-cognitive-behavioral model for obsessive- compulsive disorder

Obsessive-compulsive disorder is disabling and distressing for the affected person. The purpose of this study was to develop and validation a metacognitive-cognitive-behavioral model for obsessive – compulsive disorder. Totally، 635 participants (304 male and 331 female) were randomly selected and the instruments (OCI-R، DAS، CDS، ATQ، MCQ and OCBS) were administered on them. To test the factor structure validity of the model of metacognitive-cognitive-behavioral for obsessive–compulsive disorder were used of structure Analyses. The results of this study showed that cognitive factor through metacognitive and behavior mediators affected on the symptoms of the obsessive-compulsive disorder. And the results of the structural equation modeling supported a metacognitive-cognitive-behavioral model for obsessive-compulsive disorder. Also، the results showed that the model had the best fit to the data and is closely related to the theoretical assumptions. The model presented in this study illustrates a multidimensional approach that the model focuses on the metacognitive -cognitive-behavioral dimensions; hence، the model presented in this study is a new explanatory model. The model may prompt future research into obsessive–compulsive disorder and facilitate clinical treatment and case formulation.
