Background: There are a growing number of forced migrants worldwide. Early detection of poor adjustment and interventions to facilitate positive adaptation within these communities is a critical global public health priority. A growing literature points to challenges within the post-migration context as key determents of poor mental health. Aims: The current meta-analysis evaluated the association between daily stressors and poor mental health among these populations. Method: A systematic search in PsycINFO, PubMed, and Web of Science identified relevant studies from inception until the end of 2018. Effect sizes (correlation coefficients) were pooled using Fisher's Z transformation and reported with 95% confidence intervals. Moderator and mediator analyses were conducted. The protocol is available in PROSPERO [CRD42018081207]. Results: Analysis of 59 eligible studies (n = 17,763) revealed that daily stressors were associated with higher psychiatric symptoms (Zr=0.126–0.199, 95% CI=0.084–0.168, 0.151–0.247, p<0.001) and general distress (Zr=0.542, 95% CI=0.332–0.752, p<0.001). Stronger effect sizes were observed for mixed daily stressors relative to subjective, interpersonal, and material daily stressors, and for general distress relative to posttraumatic stress symptoms and general well-being. Effect sizes were also stronger for children and adolescents relative to adults. Daily stressors fully mediated the associations of prior trauma with post-migration anxiety, depressive, and post-traumatic stress disorder symptoms. Conclusions: This meta-analysis provides a synthesis of existing research on the role of unfavorable everyday life experiences and their associations with poor mental health among conflict-affected forced migrants. Routine assessment and intervention to reduce daily stressors can prevent and reduce psychiatric morbidity in these populations.
