This booklet contains documentation in support of the in-depth breakout sessions at the International Conference on Mental Health and Psychosocial Support (MHPSS) in Crisis Situations, 7-8 October 2019 in Amsterdam. For each breakout topic, invited experts have prepared a background paper with recommendations to inform conference participants.

Voluntary return in safety and with dignity has long been a core tenet of the international refugee regime. In the 23 articles on ‘Return’ in this issue of FMR, authors explore various obstacles to achieving sustainable return, discuss the need to guard against premature or forced return, and debate the assumptions and perceptions that influence policy and practice. This issue also includes a mini-feature on ‘Towards understanding and addressing the root causes of displacement’.

Objective: Due to traumatic experiences and highly prevalent post-migration stressors, refugees are vulnerable for developing psychopathology. To date, research has mainly evaluated trauma-focused therapies, targeting post traumatic stresss symptoms. Treatments targeting post-migration stressors are relatively understudied. The present cohort study evaluated the potential effectiveness of 7ROSES, a transdiagnostic intervention that aims to increase self-efficacy among treatment-seeking refugees in dealing with postmigration stressors.

In a previous issue of Biological Psychiatry, we reported on the efficacy of repeated intranasal oxytocin administration early after emergency department admission in preventing posttraumatic stress disorder (PTSD) symptoms, assessed 1.5, 3, and 6 months posttrauma (1). In a randomized, placebocontrolled trial, we demonstrated beneficial effects in patients with high symptom levels before treatment onset (1,2).
