          Abstract

          Background

          The aim of this study was to establish the prevalence of posttraumatic stress disorder (PTSD) and depression among Rwandese and Somali refugees resident in a Ugandan refugee settlement, as a measure of the mental health consequences of armed conflict, as well as to inform a subsequent mental health outreach program. The study population comprised a sample from 14400 (n = 519 Somali and n = 906 Rwandese) refugees resident in Nakivale refugee settlement in South Western Uganda during the year 2003.

          Methods

          The Posttraumatic Diagnostic Scale (PDS) and the Hopkins Symptom Checklist 25 were used to screen for posttraumatic stress disorder and depression.

          Results

          Thirty two percent of the Rwandese and 48.1% of the Somali refugees were found to suffer from PTSD. The Somalis refugees had a mean of 11.95 (SD = 6.17) separate traumatic event types while the Rwandese had 8.86 (SD = 5.05). The Somalis scored a mean sum score of 21.17 (SD = 16.19) on the PDS while the Rwandese had a mean sum score of 10.05 (SD = 9.7).

          Conclusion

          Mental health consequences of conflict remain long after the events are over, and therefore mental health intervention is as urgent for post-conflict migrant populations as physical health and other emergency interventions. A mental health outreach program was initiated based on this study.

          Posttraumatic stress disorder in the National Comorbidity Survey.

          Data were obtained on the general population epidemiology of DSM-III-R posttraumatic stress disorder (PTSD), including information on estimated life-time prevalence, the kinds of traumas most often associated with PTSD, sociodemographic correlates, the comorbidity of PTSD with other lifetime psychiatric disorders, and the duration of an index episode. Modified versions of the DSM-III-R PTSD module from the Diagnostic Interview Schedule and of the Composite International Diagnostic Interview were administered to a representative national sample of 5877 persons aged 15 to 54 years in the part II subsample of the National Comorbidity Survey. The estimated lifetime prevalence of PTSD is 7.8%. Prevalence is elevated among women and the previously married. The traumas most commonly associated with PTSD are combat exposure and witnessing among men and rape and sexual molestation among women. Posttraumatic stress disorder is strongly comorbid with other lifetime DSM-III-R disorders. Survival analysis shows that more than one third of people with an index episode of PTSD fail to recover even after many years. Posttraumatic stress disorder is more prevalent than previously believed, and is often persistent. Progress in estimating age-at-onset distributions, cohort effects, and the conditional probabilities of PTSD from different types of trauma will require future epidemiologic studies to assess PTSD for all lifetime traumas rather than for only a small number of retrospectively reported "most serious" traumas.

            Prevalence of serious mental disorder in 7000 refugees resettled in western countries: a systematic review.

            About 13 million people are classified as refugees worldwide, and many more former refugees have been granted citizenship in their new countries. However, the prevalence of post-traumatic stress disorder, major depression, or psychotic illnesses in these individuals is not known. We did a systematic review of surveys about these disorders in general refugee populations in western countries. We searched for psychiatric surveys that were based on interviews of unselected refugee populations and that included current diagnoses of post-traumatic stress disorder, major depression, psychotic illnesses, or generalised anxiety disorder. We did computer-assisted searches, scanned reference lists, searched journals, and corresponded with authors to determine prevalence rates of these mental disorders and to explore potential sources of heterogeneity, such as diagnostic criteria, sampling methods, and other characteristics. 20 eligible surveys provided results for 6743 adult refugees from seven countries, with substantial variation in assessment and sampling methods. In the larger studies, 9% (99% CI 8-10%) were diagnosed with post-traumatic stress disorder and 5% (4-6%) with major depression, with evidence of much psychiatric comorbidity. Five surveys of 260 refugee children from three countries yielded a prevalence of 11% (7-17%) for post-traumatic stress disorder. Larger and more rigorous surveys reported lower prevalence rates than did studies with less optimum designs, but heterogeneity persisted even in findings from the larger studies. Refugees resettled in western countries could be about ten times more likely to have post-traumatic stress disorder than age-matched general populations in those countries. Worldwide, tens of thousands of refugees and former refugees resettled in western countries probably have post-traumatic stress disorder.

              Mental health of Cambodian refugees 2 decades after resettlement in the United States.

              Little is known about the long-term mental health of trauma-exposed refugees years after permanent resettlement in host countries. To assess the prevalence, comorbidity, and correlates of psychiatric disorders in the US Cambodian refugee community. A cross-sectional, face-to-face interview conducted in Khmer language on a random sample of households from the Cambodian community in Long Beach, Calif, the largest such community in the United States, between October 2003 and February 2005. A total of 586 adults aged 35 to 75 years who lived in Cambodia during the Khmer Rouge reign and immigrated to the United States prior to 1993 were selected. One eligible individual was randomly sampled from each household, with an overall response rate (eligibility screening and interview) of 87% (n = 490). Exposure to trauma and violence before and after immigration (using the Harvard Trauma Questionnaire and Survey of Exposure to Community Violence); weighted past-year prevalence rates of posttraumatic stress disorder (PTSD) and major depression (using the Composite International Diagnostic Interview version 2.1); and alcohol use disorder (by the Alcohol Use Disorders Identification Test). All participants had been exposed to trauma before immigration. Ninety-nine percent (n = 483) experienced near-death due to starvation and 90% (n = 437) had a family member or friend murdered. Seventy percent (n = 338) reported exposure to violence after settlement in the United States. High rates of PTSD (62%, weighted), major depression (51%, weighted), and low rates of alcohol use disorder were found (4%, weighted). PTSD and major depression were highly comorbid in this population (n = 209; 42%, weighted) and each showed a strong dose-response relationship with measures of traumatic exposure. In bivariate analyses, older age, having poor English-speaking proficiency, unemployment, being retired or disabled, and living in poverty were also associated with higher rates of PTSD and major depression. Following multivariate analyses, premigration trauma remained associated with PTSD (odds ratio [OR], 2.08; 95% CI, 1.37-3.16) and major depression (OR, 1.56; 95% CI, 1.24-1.97); postmigration trauma with PTSD (OR, 1.65; 95% CI, 1.21-2.26) and major depression (OR, 1.45; 95% CI, 1.12-1.86); and older age with PTSD (OR, 1.76; 95% CI, 1.46-2.13) and major depression (OR, 1.47; 95% CI, 1.15-1.89). More than 2 decades have passed since the end of the Cambodian civil war and the subsequent resettlement of refugees in the United States; however, this population continues to have high rates of psychiatric disorders associated with trauma.
