Exploring the longitudinal relationship between anger rumination and peer victimization when controlling for sadness rumination

Abstract Anger rumination is an unconstructive cognitive-emotion regulation strategy that bears negative adjustment outcomes in youth. Anger rumination is mostly examined as an outcome of prior peer victimization. Unidirectional links between maladaptive anger regulation and later peer difficulties have also been reported. Surprisingly, whether anger rumination and peer victimization are mutually related and reinforcing is poorly explored. The present study tested reciprocal associations between anger rumination and peer victimization in 367 5th graders ( M age = 10.53, SE = 0.16; 54.2% girls). To increase precision of findings sadness rumination was treated as a confounder. Self-reported data were obtained at two times, spaced 1 year. Cross-lagged analyses showed that peer victimization predicted increases in anger rumination but not vice versa, after controlling for sadness rumination. Victimized boys were found to be more at risk for endorsing anger rumination over time as compared to victimized girls. Directions for future research and implications for practice are discussed.
