Candidate mechanisms of action of mindfulness-based trauma recovery for refugees (MBTR-R): Self-compassion and self-criticism.

Mindfulness- and compassion-based interventions may represent a promising intervention approach to the global mental health crisis of forced displacement. Specifically, Mindfulness-Based Trauma Recovery for Refugees (MBTR-R)-a mindfulness- and compassion-based, trauma-sensitive, and socioculturally adapted intervention for refugees and asylum-seekers-has recently demonstrated randomized control evidence of therapeutic efficacy and safety. Yet, little is known about potential mechanisms underlying these therapeutic effects for trauma recovery and for refugees and asylum-seekers.Thus, we examined adaptive and maladaptive forms of self-referentiality, namely self-compassion and self-criticism, as mechanisms of action for trauma recovery in a randomized wait-list control trial of MBTR-R among a community sample of 158 traumatized and chronically stressed asylum-seekers (46% female) in an urban postdisplacement setting (Middle East). Self-compassion and self-criticism were measured vis-à-vis an experimental Self-Referential Encoding Task (SRET) designed to quantify cognitive processes underlying self-compassion and self-criticism using diffusion modeling, a computational modeling approach to quantify cognitive processes underlying decision-making from behavioral reaction time data.Findings indicate that self-compassion and self-criticism were associated with trauma- and stress-related psychopathology at preintervention. Relative to wait-list controls, MBTR-R led to significant elevation in self-compassion, and reduction in self-criticism, from pre to postintervention. Finally, pre to postintervention change in self-criticism significantly mediated therapeutic effects of MBTR-R on depression and posttraumatic stress disorder (PTSD) outcomes, while pre to postintervention change in self-compassion only mediated therapeutic effects on PTSD outcomes.Findings speak to the importance of (mal)adaptive self-referentiality as a target mechanism in MBIs and trauma recovery broadly, and among refugees and asylum-seekers specifically.
