Inclusion and Exclusion Criteria.

Inclusion Criteria	Exclusion Criteria
Peer-reviewed articles documenting empirical research, including but not limited to randomized controlled trials, controlled and uncontrolled studies, mixed-method studies, case series	Books, dissertation, conference papers, non-peer-reviewed articles, case studies
Participants experienced elevated level of distress as a result (e.g., traumatic stress symptoms, depression, anxiety and quality of life) and at least one of these indicators of distress were reported as an outcome	Not written in English
Populations including children and adult experiencing at least one traumatic event with actual or potential actual or threatened death, serious injury, or sexual violence as defined by the DSM-5 (APA, 2013) who were currently living in states of ongoing threat specifically in organized violence (political, civil or community violence) or intimate partner violence. The context of the ongoing threat is linked to the “index” traumatic event but not due to daily stressors or hassles	Articles not describing continuous threat; or when the ongoing threat context was not related to community/ political/ war violence, or intimate partner/ domestic violence
Interventions were psychologically informed targeting distress relating to the traumatic event(s). The interventions followed the top two levels of IASC guidelines on MHPSS which meant that they were focused, non-specialized support (focused individual, family or group interventions by trained and supervised workers, basic mental healthcare by primary healthcare workers), or specialized services (psychological or psychiatric supports by specialists for people with severe mental disorders) (IASC, 2007).	Exclusion of trauma types included medical trauma, combat/ veteran trauma, work-related trauma (e.g., police, paramedics, healthcare professionals), post-conflict areas or refugees resettled in camps in another country that were not experiencing conflicts, developmental trauma, children affected by parental conflict, vicarious trauma
	Papers published in “predatory journals.” We decided to exclude studies from predatory journals based on the recommendations from (Munn et al., 2021). In the absence of a standardized definition of “predatory journal,” only indexed studies on bibliographic databases with stringent indexing criteria were included. When assessing the studies especially the ones from citation search and when the publishers’ credibility was queried, we measured those journals against criteria such as whether they were a member of Committee on Publication Ethics (COPE) used the Think, Check, Submit campaign checklist (http://thinkchecksubmit.org/).
