A comprehensive model for obsessive-compulsive disorder symptoms: a cross-cultural investigation of cognitive and other vulnerability factors

Yorulmaz, Orçun
The current coginitive models of the Obsessive-Compulsive Disorder (OCD) symptoms focuses on the different cognitive factors. Like other nonspecific and noncognitive variables, these factors may also function as vulnerability factors. However, they have been mostly studied separately and majority of the findings in the literature come from the Western samples. Accordingly, the studies examining these factors together and the impact of the culture in these studies are sparse in number. The present study suggested a comprehensive cognitive model for OCD symptoms, including several distal and proximal vulnerability factors. It was aimed to adapt three instruments to examine the interrelationships among the vulnerability factors and OCD symptoms in different cultures. Relevant ten instruments were administered to the university students from Turkey and Canada. The analyses showed that Turkish versions of three instruments had satisfactory psychometric properties for Turkish students. These analyses also revealed some cross-cultural similarities and differences in these factors and OCD symptoms. Neuroticism, age, introversion, OCD beliefs on responsibility/threat estimation, perfectionism/certainty and thought-action fusion in likelihood dimension were found to be associated with the OCD symptoms in both Turkish and Canadian samples. The relational paths between non-specific, appraisal and control factors, and OCD symptoms were also significant in both samples. However, religiousness was only significant factor in OCD symptoms and contributed to several belief and control factors toward these symptoms, only for Turkish subjects. The analyses of the religiousness differences indicated that psychological fusion in general and in morality was more related to the religiosity for Canadian Christians. Besides, Turkish students seemed to utilize worry more for OCD symptoms; whereas, Canadian participants used self-punishment. These common and unique patterns of the relationships were discussed within relevant findings about characteristics of the religion and culture.

Further Support for Responsibility in Different Obsessive-Compulsive Symptoms in Turkish Adolescents and Young Adults
Yorulmaz, Orcun; Altin, Muejgan; Karanci, Nuray (Cambridge University Press (CUP), 2008-10-01)
According to the cognitive model, an inflated sense of responsibility is an important cognitive mediator both in the development and maintenance of obsessive-compulsive disorder (OCD). Empirical findings assign differential roles to responsibility in different kinds of obsessive-compulsive (OC) symptoms. However, findings that suggested a different function for responsibility revealed the need for an operational definition of responsibility and its multi-factorial factorial structure. Few studies have exami...
