The Factorial Structure of the Obsessive-Compulsive Sale in the Saudi Environment: A Psychometric Study on Psychiatric Clinic outpatients

Abstract

The present study aims to investigate the structural validity of the Dimensional Obsessive-Compulsive Scale (DOCS). In addition, estimating the factor congruency of the Saudi-Arabic translation of the scale with other available studies. That for make availability of a valid measurement of the Obsessive- Compulsive Disorder (OCD) in the current culture. The present study sample included three groups, the first and the second groups consisted of both OCD patients and healthy individuals (the healthy group as a controller group). Every group included 127 participants and their ages ranged between 18 and 60 years old. The third group recruited from the general population (n= 2758; ages ranged from 18 to 60 years old). The DOCS was utilized to assess the symptoms of the OCD among all the study sample. The results indicated that there was a validity of the factorial structure of the DOCS beside the acceptable and excellent factor congruency values with the relevant studies. In addition, the CFA results showed fair and significant fit indices of the four-factor model. Reliability analysis based on the internal consistency and the test-retest methods, appeared high values. Receiver Operating Characteristic (ROC) curve analysis showed that the DOCS has a high ability in discriminant diagnosis.
