Mistake Rumination Scale: psychometric properties for the Turkish version

Abstract

The Mistake Rumination Scale (MRS) was developed to evaluate the inclination to engage in mistake rumination (MR), a reaction to perceived mistakes in the form of intense, repetitive negative thoughts. The present study aimed to investigate the psychometric qualities of the Turkish version of the MRS in 2 studies. Data were collected from 214 participants (118 females) between the ages of 18 and 56 (M = 33.45, SD = 11.82) through measures of MR, repetitive negative thinking, perfectionism, procrastination, depression, and anxiety. The findings confirmed the original factor structure and indicated adequate reliability, convergent, and incremental validity. In the second study, the criterion-related validity of the MRS was tested using an experimental design. Participants (127 individuals aged between 18 and 28) were asked to imagine committing a series of mistakes or a regular event. Results provided support for the criterion-related validity of the MRS. In conclusion, MRS can be utilized to assess MR in Turkish individuals.
