Abstract
Anger rumination has recently received attention as a mechanism of action for cognitive behavioral therapy for problematic anger. However, further research is needed to more precisely elucidate the underlying mechanisms, and no studies have followed longitudinal relationships between anger rumination, trait anger, and anger-in. A latent growth curve model was used with a sample of 75 Japanese undergraduates to test the hypothesis that anger rumination would be correlated with slopes of trait anger and anger-in over 4months. Results indicated that anger rumination directly related to trait anger over time. Although there was no correlation between anger rumination and anger-in, anger-in was strongly covariant with trait anger over time. Moreover, compared to the low anger rumination group, the high anger rumination group was more likely to perceive a wide range of situations with frustration and to suppress anger. These results suggested that anger rumination is a potential risk factor for trait anger and anger-in. In terms of prevention, it may be clinically effective to selectively treat those with high anger rumination.
