Obsesif-Kompulsif Envanteri-Revize’nin (OKE-R) Türkçe Formu’nun Klinik ve Klinik Olmayan Örneklemlerde Geçerliği

INTRODUCTION The Obsessive-Compulsive Inventory-Revised (OCI-R) is a widely used self-report instrument developed to overcome the problems with the available instruments. The aim of this study was to assess the psychometric properties of the revised Obsessive Compulsive Inventory (OCI-R) in Turkish sample. METHODS The psychometric properties of the Turkish version of the Obsessive-Compulsive Inventory-Revised (OCI-R) were assessed in clinical samples (n=44 for patients with obsessive-compulsive disorder (OCD), and n=44 for patients with major depression (MD) and a non-clinical student sample (n=287). RESULTS The confirmatory factor analysis demonstrated that the original six-factor structure was valid in the Turkish sample. The overall and each of the subscales showed moderate to good internal consistency and convergent validity as well as test-retest reliability. However, the Cronbachs alpha was excessively low for the hoarding subscale in the OCD group. The total and subscale scores of the OCI-R satisfied at discriminating patients with OCD from both patients with MD and healthy controls, with an exception of the neutralizing subscale. CONCLUSION The Turkish version of the OCI-R did not reveal sound psychometric properties. Findings are discussed in the light of current theoretical considerations.

The predictive value of interpersonal schemas, perfectionism, and thought action-fusion in obsessive-compulsive disorder / Obsesif-kompulsif bozuklukta kişilerarası şemalar, mükemmeliyetçilik ve düşünce-eylem kaynaşmasının yordayıcı rolü

The predictive value of interpersonal schemas, perfectionism, and thought action-fusion in obsessive-compulsive disorder Objective: Cognitive vulnerability factors are central in the etiology of obsessive-compulsive disorder. Nosological classifications among symptom clusters have been developed to enable the understanding of possible mechanisms underlying obsessive compulsive symptoms. Previous researchers have emphasized that perfectionist attitudes and thought action-fusion link to increase in obsessive compulsive symptom severity in clinical and nonclinical samples. However, multi-dimensional relations between obsessive compulsive symptoms and vulnerability factors such as interpersonal schemas have received little attention. This study examined connections between cognitive vulnerability factors and obsessive-compulsive symptoms. Method: The data collected from 263 university students. Associations between variables were analyzed by using structural equation modeling. Results: The results of the study indicated that dysfunctional interpersonal schemas were the most hazardous factors that predict perfectionist attitudes, thought action-fusion, and symptom severity in obsessive compulsive disorder. Washing and precision were the final manifestation symptoms mediated by checking. Maladaptive interpersonal schemas, perfectionist attitudes, and thought action-fusion were all vulnerability agents in the development of obsessive compulsive symptoms. Checking played a prominent role in exacerbation of obsessive –compulsive symptoms. Conclusion: Onset and maintenance of obsessive-compulsive disorder is a multidimensional process. Negativistic interpersonal beliefs seem to be an important risk factor. Findings are discussed in the light of current theoretical considerations.
