Reliability and validation of the Turkish adaptation of the mistake rumination scale

The present study aimed to evaluate the validity and reliability of Turkish adaptation of the Mistake Rumination Scale (MRS) in university students. The study group consisted of 372 participants from different faculties, aged between 17 and 39 years and mainly female. We first translated Turkish of the MRS. Then, we analyzed the scale in terms of reliability and validity. The findings indicated that the MRS-Turkish Form confirmed seven items in one factor with good factor loadings. Good fit values were determined with the MRS-Turkish Form. The MRS-TF has good reliability coefficients. The mistake rumination was moderately positively correlated with ruminative thought styles and moderately negatively correlated with cognitive control and flexibility. These results demonstrated that the MRS-Turkish Form can be validly and reliably performed to Turkish culture.
