Mental health is a key issue for populations affected by conflict. The evidence base on the mental health of internally displaced Colombians is undefined, as well as protective strategies utilised by this group. This systematic literature review aims to identify and assess the evidence base on the mental health of Colombian internally displaced persons (IDPs). Specific objectives are to examine (1) prevalence and incidence rates of common mental disorders (CMDs) amongst adult Colombian IDPs, (2) risk factors associated with CMDs amongst this group, and (3) coping strategies used by these displaced persons. A database search was conducted in May 2021. Included studies reported quantitative and/or qualitative mental health outcomes of CMDs, and/or coping strategies, among Colombian IDPs. The search yielded 34 articles. Study quality ranged from adequate to poor, with several containing serious shortcomings. PTSD prevalence ranged from 1.2%-97.3%, anxiety from 0.0%-60.0%, depression from 5.1%-100%, and problematic alcohol use from 8.0%-33.5%. Factors significantly associated with CMDs were inconsistent. Seeking social support and problemsolving strategies were the two most-commonly reported coping strategies. Associations between mental health and coping were largely unreported. As the evidence base is weak, there is a clear need for better quality research in this area. Keywords: mental health, common mental disorders, coping, internally displaced persons, Colombia rates of CMDs, (2) risk factors associated with CMDs, and (3) coping strategies used by Colombian IDPs.
Methods
Search StrategyThis systematic review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines (Moher et al., 2009). An initial search of nine databases (MEDLINE, EMBASE, Global Health, PsycINFO, CINAHL Plus, Web of Science, LILACS, SciELO and Open Grey) was conducted on 15 July 2019 and updated on 16 May 2021. Search terms focused on CMDs, IDPs, and Colombia. The term 'coping' was deliberately not included in the search. The nuanced nature of coping meant that some authors may not have explicitly framed their studies about coping but would nevertheless have incorporated key elements of coping that matched the definition and inclusion criteria of this review. The MEDLINE search strategy of the updated search is appended online (Appendix A).Additional relevant articles were identified through manual searches of reference lists of included articles and related reviews, and a forward-citation Google scholar search. Websites of non-governmental organisations (NGOs) and Colombian government websites were manually searched to identify relevant grey literature.
Eligibility CriteriaWe included observational and intervention studies which reported prevalence and/or incidence of CMDs (including anxiety [PTSD and panic disorders], depression, somatization disorders and substance abuse) amongst adult Colombian IDPs, as well as qualitative studies exploring Colombian IDPs' coping strategies.
