Determinants of Mental Illness Among Humanitarian Migrants: Longitudinal Analysis of Findings From the First Three Waves of a Large Cohort Study
Year: 2018
Type: article
Study design: Observational Study
Abstract: Background: As refugee numbers grow worldwide, understanding prevalence and determinants of mental illness in this population becomes increasingly important. We used longitudinal data to examine the initial years of resettlement in Australian refugees with a focus on ethnic-like social support. Methods: Three annual waves from a longitudinal, nationally representative cohort of 2399 humanitarian migrants recently resettled in Australia were examined for two mental illness outcomes: Posttraumatic Stress Disorder indicated by positive PTSD-8 screen; and 'High risk of Severe Mental Illness' (HR-SMI) by Kessler Psychological Distress Scale (K6) ≥19. Generalised linear mixed models examined demographic and resettlement factors. Findings: Contrary to predictions, high prevalence of mental illness persisted over 3 years. At baseline, 30·3% (95%CI 28·5-32·2) screened positive for PTSD and 15·4% (95%CI 14·0-16·9) had HR-SMI. Over the 3-years, 52·2% met screening criteria for mental illness. PTSD was associated with older age, females, Middle Eastern birthplace, increasing traumatic events, more financial hardships, having a chronic health condition and poor self-rated health. HR-SMI was associated with females, Middle Eastern birthplace, unstable housing, more financial hardships, having a chronic health condition, poor self-rated health, and discrimination. Also contrary to predictions like-ethnic social support was positively associated with PTSD (OR: 1.51, 95%CI 1·10-2·09). Interpretation: There is high prevalence of mental illness throughout initial years of resettlement for refugees migrating to Australia. Our unexpected finding regarding like-ethnic social support raises future avenues for research. Predictors of mental illness in the post-migration context represent tangible opportunities for intervention and are likely relevant to similar resettlement settings globally.
