This document includes the recommendations and describes the methodology used to develop them. Important issues that should be considered when interpreting the recommendations, and translating them into practice, are highlighted. It was decided to publish the recommendations and position papers in advance of the book as they represent a comprehensive and up-to-date synthesis of high quality research evidence that is likely to help practitioners in their work.

For the past two decades, there has been substantial debate about whether there are qualitatively different symptom profiles that can develop from different experiences of traumatic events. It has been proposed that more complex symptom profiles, called “complex PTSD,” can emerge from events that involve multiple, chronic or repeated types of traumas that are of an interpersonal nature and from which escape is difficult or impossible such as childhood abuse, domestic violence, genocide campaigns and being a prisoner of war (Herman, 1992).

Persistent complex bereavement disorder (PCBD) is a disorder of grief included in DSM-5. Prolonged grief disorder (PGD) is included in ICD-11. Few studies have evaluated and compared criteria sets for DSM-5 PCBD and ICD-11 PGD. The current study explored and compared the dimensionality, prevalence rates, diagnostic agreement, concurrent validity, and socio-demographic and loss-related correlates of both criteria sets.

Background: Despite numerous calls for a more evidence-based provision of post-disaster psychosocial support, systematic analyses of post-disaster service delivery are scarce.

Objective: The aim of this review was to evaluate the organization of post-disaster psychosocial support in different disaster settings and to identify determinants.
