Purpose: The aim of this study is to examine the validity and reliability of the Turkish version of the Anger Rumination Scale (ARS). Method: The first phase of this study was conducted with 405 students from Sakarya University and the second phase was conducted with 544 students from Anadolu University. In the first phase, language equivalance, exploratory factor analysis, the internal consistency, and test-retest reliability were employed. The next phase, confirmatory factor analysis and concurrent validity were employed. Results: The total variance explained was 52% and factor loadings ranged from .35 to .86. Fit index values of the model were x2= 420, x2/df = 2.88, CFI=.90, GFI= .90 RMSEA=.06, and SRMR= .05. Internal consistencies varied between .64 and .78 and test-retest reliability coefficients ranged between .79 and .86 for four subscales. ARS was negatively corerelated with life satisfaction and positively correlated with vengeance. Conclusions: Overall findings demonstrated that this scale had high validity and reliability scores and that it may be used as a valid and reliable instrument in order to assess tendency to anger rumination. Nevertheless, further studies that will use ARS are important for its measurement force. [Anadolu Psikiyatri Derg 2014; 15(4.000): 328-334]
