Individual differences in anger and displaced aggression: The role of metacognitive beliefs and anger rumination.

Abstract

Metacognitive model is a theoretical approach aimed to explain emotion dysregulation and others emotion-related issues, such anger, and aggressive behavior. From this model, people having higher maladaptive metacognitive beliefs (e.g., "I can't control my thoughts") are more likely to activate and maintain anger rumination and, in turn, to experience higher levels of anger and to act aggressively. Preliminary evidence shows the role of metacognitive beliefs on anger rumination and anger levels, whereas no studies have examined its association with aggressive behavior. This study first examined the associations between metacognitive beliefs, anger rumination, anger levels, and the propensity to engage in displaced aggression, and second, the mediation role of anger rumination in the relations among metacognitive beliefs and anger and displaced aggression. Participants were 947 students and non-students from general population recruited in two different countries (Australia and Spain). Correlational analyses revealed a similar pattern of results in the Australian and Spanish sample, with participants having dysfunctional metacognitive beliefs also showing higher anger rumination, higher levels of anger and a higher tendency to act aggressively. Structural equation analyses revealed the associations of metacognitive beliefs with anger levels and displaced aggression was fully mediated by anger rumination in both samples. These results suggest that metacognitive beliefs should be considered in comprehensive models and in the therapy of anger problems and aggression.
