PSYCHOMETRIC PROPERTIES OF THE OBSESSIVE-COMPULSIVE INVENTORY-REVISED IN A TURKISH ANALOGUE SAMPLE.

Abstract

The Obsessive-Compulsive Inventory-Revised (OCI-R) assesses distress associated with the symptoms of obsessive-compulsive disorder (OCD). This study reports on the psychometric properties of the Turkish version of the OCI-R as a widely known measure. The sample consisted of 319 Turkish university students (67.1% women; M age = 21.5, SD = 2.0). The questionnaire battery included measures of OCD symptoms, specific cognitions, thought control, and personality characteristics. A target rotation analysis supported the factorial validity of the Turkish OCI-R as indicated by its replicability with the original factor structure (i.e., checking, washing, obsessing, hoarding, ordering, and mental neutralizing). High-scoring OCD symptom groups also significantly differed on the Turkish OCI-R and thus presented preliminary evidence for its criterion validity. Correlational analysis supported convergent and divergent validity of the measure, with significant correlations between the Turkish OCI-R and OCD symptoms, OCD-specific beliefs, two thought control strategies (e.g., worry and punishment), and neuroticism, but not with psychoticism or extraversion. The current findings provide initial evidence of sound psychometric properties for the Turkish OCI-R in a nonclinical sample.
