The Event Related Rumination Inventory: A Validity and Reliability Study

This research aims to examine the validity and reliability of the Turkish version of the Event-Related Rumination Inventory (ERRI). The validity and reliability of the scale were investigated by Cronbach's alpha, explanatory and confirmatory factor analysis, and criterion-related validity methods. The Impact of Events Scale, the Posttraumatic Growth Inventory, the Core Beliefs Inventory, the Life Satisfaction Questionnaire, the Ruminative Responses Scale, and the COPE-SF were used to assess criterion-related validity. The participants in this study consisted of 574 college students (390 female and 184 male) who were screened for having experienced highly stressful life events. The results of confirmatory factor analysis demonstrated that the 20 items loaded on two factors and the two-dimensional model was well fit (x²=506.13, df=163; x²/df=3.10, p=.00, RMSEA=.061, NNFI=.98, CFI=.99, GFI=.94, AGFI=.90, and SRMR=.053). In the criterion validity, the results indicated that there are significant positive relationships between total ERRI and impact of events, posttraumatic growth, core beliefs, and coping styles, and significant negative relationships between rumination styles and life satisfaction. The internal consistency coefficients of the two subscales were.94 and.88, respectively. The overall internal consistency coefficient of the scale was.94. Overall findings indicated that the scale had high validity and reliability scores and that it may be used as a valid and reliable instrument in Turkish population to measure intrusive and deliberate rumination in the aftermath of a stressful life event.
