Background: Mistake rumination is more prevalent in adolescents and has an adverse effect on various aspects of their lives.
Aims: The aim of the current study was to examine psychometric properties of mistakes rumination scale.
Methods: This study was a fundamental practical study, in terms of data collection, this study was a survey, and in terms of methodology, this study is a questionnaire-making study in the form of a correlation method. The research statistical population of this study included all undergraduate students at Alzahra University who studied in 2019. A convenience sampling method was used to recruit 300 undergraduate students.The data were analyzed using composite reliability, content validity index, content validity ratio and confirmatory factor analysis.
Results: The composite reliability value for the Persian version of the mistake rumination scale was .74, indicating a desirable reliability. Content validity ratio was more than 78% and content validity index was more than 80%, indicating good content validity of the scale. The results of confirmatory factor analysis showed that factor loading values were greater than 0.66 and all paths from items to latent variable were significant at the level of .001, indicating the scale had an appropriate construct validity. Except for the index of CMIN/DF 1.09 (p=.001); other indices showed an acceptable model fit (GFI 0.92, CFI 0.92, IFI 0.92, and RMSEA .08). Convergent validity for the scale was .5, indicating an acceptable convergent validity.
Conclusion: The result of confirmatory factor analysis showed that mistake rumination scale has one-dimensional structure. Given the desirable psychometric properties of the Persian version of the mistake rumination scale, it can be suggested to psychologists and counselors to employ in for doing research and diagnostic situations.
