Objectives. Mindfulness training reduces anger and aggression, but the mechanisms of these effects are unclear. Mindfulness may reduce anger expression and hostility via reductions in anger rumination, a process of thinking repetitively about angry episodes that increases anger. Previous research supports this theory but used measures of general rumination and assessed only the present-centered awareness component of mindfulness. The present study investigated associations between various aspects of mindfulness, anger rumination, and components of aggression.
Method. The present study used self-report measures of these constructs in a cross-sectional sample of 823 students.
Results. Structural equation modeling revealed that anger rumination accounts for a significant component of the relationship between mindfulness and aggression, with the largest effect sizes demonstrated for the nonjudgment of inner experiences facet of mindfulness.
Conclusion. Nonjudgment and present-centered awareness may influence aggression via reduced anger rumination. The importance of examining mindfulness as a multidimensional construct is discussed.
