Abstract

Background & Statement of the problem: The previous years witnessed a noticeable increase in obsessive-compulsive disorder, which caused the need for an evaluation tool for it. Therefore, the study sought a tool to evaluate obsessive beliefs in the Jordanian environment.

Objectives: The current study aimed to adapt and examine the psychometric properties of the Obsessive Beliefs Questionnaire - 44 among a sample from the city of Amman.

Methods: Several measures were applied to a sample consisting of (360) participants divided as follows: (83) clinical sample diagnosed with Obsessive Compulsive Disorder and a sample of (277) Non-clinical.

Results: The study reached several results, including high structural and discriminant validity, as the questionnaire demonstrated its ability to distinguish between clinical and non-clinical samples. As for the implications of reliability, they were examined in two ways: Internal consistency and Test Re–Test Method It indicated a high degree by the internal consistency method, where the Cronbach alpha coefficient for the total questionnaire reached (0.94), and as for the Test Re–Test Method, the Pearson correlation coefficient between the two application periods for the total questionnaire reached (0.75**), Based on the above, it is concluded that the questionnaire has high psychometric properties.

Conclusions (Recommendations and contributions): The study indicates that the tool has high psychometric properties and therefore recommends using the scale to evaluate obsessive beliefs.
