Background: Although growing studies support features of co-rumination as a vulnerability factor in internalizing symptoms and positive factor in friendship, little attention has been paid to the psychometric properties of the Co-Rumination Questionnaire (CRQ). Objectives: This study aimed to determine the psychometric properties of the Persian version of this questionnaire. Methods: This research is a descriptive-exploratory study and 550 high school students who were selected by random cluster sampling from schools in Tehran. They completed CRQ, Beck depression inventory-II (BDI-II), and ruminative response scale (RRS) from winter 2014 to summer 2015. Construct validity, internal consistency reliability, and factor structure were investigated. Results: The factor analysis identified two interpretable factors with the eigenvalue higher than 2. The results from concurrent validity measurement in the current study showed that co-rumination has a positive correlation with depression signs (P < 0.01) and rumination response style (P < 0.01). The CRQ validity was determined using the half-split method employing Spearman-Brown (0.82) and Guttman correlation test (0.81) and internal consistency (0.90). According to these values, this questionnaire has acceptable internal consistency reliability. Conclusions: The Persian version of CRQ has reliability and validity for assessing co-rumination among adolescent participants. This study provides primary evidence on the applicability of the Persian version of the CRQ in the Iranian population. Copyright © 2020, Author(s).
