Adaptation of Self-Critical Rumination Scale into Turkish and investigation of its psychometric properties

In recent years, self-critical rumination has been defined as a separate rumination type and the Self-Critical Rumination Scale (SCRS) has been developed. The aim of this study was to adapt SCRS into Turkish and to examine its psychometric properties. In the first stage of the study, SCRS and other instruments that evaluate structures related to self-critical rumination were administered to 248 participants. In the second stage which was conducted to confirm the factorial structure of the SCRS, different data including 250 participants were examined. As a result of the exploratory and confirmatory factor analyses, the scale was shown to exhibit a single factor structure. In reliability analyses, internal consistency and test-retest coefficients of the scale were found high. In addition, scale items were found to be able to distinguish between individuals with low and high self-critical rumination. Validity analyses showed that the scale had significant and expected relationships with the structures related to self-critical rumination (e.g. self-criticism, repetitive thinking, metacognition). Also, it was shown that the scores obtained from the clinical variables chosen as criterion variables (depression, anxiety, stress) were significantly different between participants whose self-critical rumination scores were low and high. In support of the scale's incremental validity, it was found that self-critical rumination significantly predicted depression and anxiety symptoms even after controlling for the levels of self-criticism and repetitive thinking. The Turkish version of the SCRS has similar psychometric properties to its original form and is a valid and reliable measure that can be used to measure self-critical rumination in our country.
