Validity and Reliability Assessment of the Persian Version of the Co-Rumination Questionnaire

Co-rumination refers to excessively frequent discussing personal problems within dyadic relationship. The purpose of present study was to investigate the validity and reliability assessment of the Persian version of the Co-rumination questionnaire.

In a correlational design, 167 adults who were referred to health care centers in Mashhad were selected with multistage cluster sampling. Data were collected by a Co-rumination Questionnaire, Depression, Anxiety, Stress Scale (DASS-21), and Rumination Response Scale (RRS). Exploratory factor analysis, Pearson correlation coefficient and multivariate analysis of variance were used to analyze the data.

The results showed that the scale had three factors of rehashing, encouraging problem talk and mulling which explains 66.01% of the variance. Co-rumination had a positive and significant relationship with stress, anxiety, depression and rumination (p < 0.01). Age had no significant relationship with Co-rumination. But differences were significant based on gender, and women had higher mean.

It seems that the Persian version of the Co-rumination Questionnaire has a proper validity and reliability in common population and can be used in related research.
