Fissler, M., et al. (2016). An Investigation of the Effects of Brief Mindfulness Training on Self-Reported Interoceptive* Awareness, the Ability to Decenter, and Their Role in the Reduction of Depressive Symptoms. Mindfulness, 1-12.
Abstract. Mindfulness-based interventions for the prevention and treatment of depression are predicated on the idea that interoceptive awareness represents a crucial foundation for the cultivation of adaptive ways of responding to negative thoughts and mood states such as the ability to decenter.
The current study used a multi-dimensional self-report assessment of interoceptive awareness, including regulatory and belief-related aspects of the construct, in order to characterize deficits in interoceptive awareness in depression, investigate whether brief mindfulness training could reduce these deficits, and to test whether the training unfolds its beneficial effects through the above-described pathway.
Currently depressed patients (n = 67) were compared to healthy controls (n = 25) and then randomly allocated to receive either a brief training in mindfulness (per-protocol sample of n = 32) or an active control training (per-protocol sample of n = 28). Patients showed significant deficits across a range of regulatory and belief-related aspects of interoceptive awareness, mindfulness training significantly increased regulatory and belief-related aspects of interoceptive awareness, and reductions in depressive symptoms were mediated through a serial pathway in which training-related increases in aspects of interoceptive awareness were positively associated with the ability to decenter, which in turn was associated with reduced symptoms of depression. These results support the role of interoceptive awareness in facilitating adaptive responses to negative mood.

Peters, J. R., et al. (2015), Anger Rumination as a Mediator of the Relationship Between Mindfulness and Aggression: The Utility of a Multidimensional Mindfulness Model. Journal of Clinical Psychology. doi: 10.1002/jclp.22189. Published online ahead of inclusion in an issue. Abstract.
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.
