The purpose of the present study was to investigate the psychometric properties of the Co-rumination questionnaire in women. In a correlational design, 119 women who referred to health care centers of Mashhad city were selected with the convenience sampling. Data were collected by Co-rumination Questionnaire (CRQ), and Depression, Anxiety and Stress Scale (DASS 21). Confirmatory factor analysis, convergent validity and internal compatibility with SPSS.25 and SmartPLS.3.3.0 software were evaluated. The results showed that the questionnaire has three factors. This structure has a good fit. Cronbach’s alpha coefficients ranged from 0.86 to 0.95 and Spearman-Brown’s split-half coefficients ranged from 0.90 to 0.95, indicating good reliability of the questionnaire. Co-rumination had a positive and significant relationship with depression and could predict it.
