Anger Rumination Scale: Validation in Mexico.

Abstract. The aim of the study was to assess the validity of the Anger Rumination Scale (ARS; Sukhodolsky, Golub, &Cromwell, 2001) in a Mexican sample (n = 700, Mage = 38.6, SD = 12.42). Through confirmatory factor analysis andusing modification indices, the four-factor structure of the original scale was replicated: angry afterthoughts,thoughts of revenge, angry memories, and understanding of causes. In addition, the four-factor model had bettergoodness of fit indices than rival models with three and two factors. Alpha reliabilities were acceptable (.72 ?.89).ARS results correlated with measures of state anger, trait anger, anger expression, and anger control (negatively);correlations were significant (ps < .001) ARS outcomes also correlated (ps < .001) with physical and verbal aggression,hostility, anger, and emotion suppression, suggesting convergent validity. Men reported more thoughts of revengethan women (p < .001; Eta squared = .026), but there was no evidence of gender differences on the other anger ruminationscales, or in total scores.
