Correlates of grief-related disorders and mental health outcomes among adult refugees exposed to trauma and bereavement: A systematic review and future research directions
Résumé
Background With conflict driving millions of refugees away from their homes worldwide, there has been an increase in interest in the field of refugee trauma. However, while trauma and bereavement interlink, prior studies have focused on trauma and its related disorders (PTSD) and predictive factors. This paper reviewed up-to-date literature on the prevalence rates of prolonged grief disorder (PGD), its comorbidities, and associated risk factors among adult refugees. Method We systematically reviewed the literature using five databases (PsycINFO, PsycARTICLES, Psychology and Behavioral Sciences Collection, Academic Search Elite, and PubMed). The process of study selection was designed according to PRISMA guidelines. Results The initial search generated 126 articles, of which 12 met the inclusion criteria. The pooled prevalence of PGD was 33.2% (95% CI: 15.2–54.2%). Being an older refugee, traumatic and multiple losses implying the death of first-degree relatives appeared to be consistent risk factors for PGD, combined PTSD/PGD, depression, idioms of distress, and functional impairment. PGD, PTSD, and PTSD/PGD intersect on PTSD-intrusions and painful memories. Limitations All included studies adopted a cross-sectional design, thus limiting the understanding of causal pathways. Conclusions Our findings showed that the high prevalence of PGD and related comorbidities were influenced by the load of traumatic circumstances surrounding the death(s). The findings shed light on the current proposed grief-related diagnostic criteria . Psychopathological and transcultural aspects are discussed, and we provide concrete recommendations for improvements to future research in this field.
