Psychometric Properties for Arabic Jordanian Modified Version of Dimensional Obsessive-Compulsive Scale (DOCS)

Objectives: This study aimed to translate, adapt the Dimensional Obsessive-Compulsive Scale (DOCS), and examine its Psychometric Properties in terms of validity and reliability for the Jordanian environment. Methods: To achieve the objectives of the study, the Dimensional Obsessive-Compulsive Scale and the Yale-Brown Obsessive-Compulsive Scale were translated and applied to an available sample of Jordanian society. The study sample consisted of (670) participants, divided into two samples: A non-clinical sample (612), and a clinical sample of (58) Diagnosed with obsessive compulsive disorder. Results: Validity indicators were examined in several ways, including: Construct validity through confirmatory factor analysis; the results of the factor analysis of the scale's items indicated the presence of four factors identical to the original version. Discriminant validity was also examined by comparing the performance of the Non-clinical sample with the Clinical sample using a T-test for independent samples. It indicated the scale's ability to distinguish well between participants. It was found that the reliability coefficient was achieved in two ways: the first was by finding the reliability coefficient using the internal consistency method according to the Cronbach alpha coefficient, where it reached (.92) for the Non-clinical sample, and (.83) for the Clinical sample. The second method was using the Test re – test Reliability method; where the reliability coefficient in nun- clinical sample (.75). Conclusion: The study indicates that there is appropriate Validity and Reliability for the measure of the Dimensional Obsessive-Compulsive Scale in the Jordanian environment.
