Skin conductance response to trauma interview as a candidate biomarker of trauma and related psychopathology in youth resettled as refugees.

Background: Posttraumatic stress symptoms (PTSS) include a constellation of physical and emotional profiles that youth exposed to trauma may experience. An estimated 20% of youth are exposed to trauma, and in refugee populations, up to 54% experience posttraumatic stress. Given the physical and mental health consequences associated with trauma exposure and subsequent psychopathology, identifying biomarkers of symptom severity is a top research priority.Objective: Previous research in adults found that skin conductance responses to trauma interview predicted current and future PTSS. We extended this method to refugee youth exposed to civilian war trauma and forced migration, to examine associations between PTSS and skin conductance in this uniquely vulnerable child and adolescent population.Methods: 86 refugee youth ages 7-17 years completed a trauma interview and assessment of self-reported PTSS. The mobile eSense app on a iPad was used to obtain continuous recordings of skin conductance level (SCL) during a trauma interview (trauma SCL). Skin conductance response (SCR) was calculated by subtracting the baseline SCL from the maximum amplitude of the trauma SCL.Results: SCL during trauma was significantly greater than baseline SCL, Trauma exposure was significantly associated with SCR to trauma interview, R2 = .084, p = .042. SCR to trauma interview was positively correlated with reexperiencing (R2 = .127, p = .028), and hyperarousal symptoms (R 2 = .123, p = .048).Conclusions: The present study provides evidence for feasibility of SCR to trauma interview as a candidate biomarker of PTSS in youth. This is the first study to look at SCR to trauma interview in youth resettled as refugees and is part of the limited but growing body of research to look at biomarkers in refugee cohorts more broadly. As the number of forcibly displaced persons surges, early detection and prevention of trauma-related psychology is becoming more important than ever. HIGHLIGHTS: Using the mobile eSense app, we demonstrate that skin conductance is measurable in a variety of research settings and that skin conductance response may be a biological indicator of trauma and related psychopathology - namely re-experiencing symptoms - in youth resettled as refugees.

Mental Health of Refugees and Torture Survivors: A Critical Review of Prevalence, Predictors, and Integrated Care.

Civilian war trauma and torture rank among the most traumatic life experiences; exposure to such experiences is pervasive in nations experiencing both internal and external conflict. This has led to a high volume of refugees resettling throughout the world with mental health needs that primary care physicians may not be screening for and prepared to effectively address. In this article, we review the literature on demographics, predictors, mental health outcomes of torture, and integrated care for the mental health needs of refugees. We searched PubMed and PSYCINFO databases for original research articles on refugees and mental health published in the English language between 2010 and present. Nine percent of 720 adults in conflict areas in Nepal, with predominance of literate married males, met the threshold for Post-Traumatic Stress Disorder (PTSD), 27.5% for depression, and 22.9% for anxiety. While, PTSD rate has been documented as high as 88.3% among torture survivors from Middle East (ME), Central Africa (CA), South Asia (SA), Southeast Europe (SE). Depression was recorded as high as 94.7% among 131 African torture survivors and anxiety as high as 91% among 55 South African torture survivors. Torture severity, post-migration difficulties, and wait time to receive clinical services were significantly associated with higher rate of mental health symptoms. Mental health screening is not a standard component of initial physical exams for refugees, yet these individuals have had high trauma exposure that should inform clinical care. Integrated care models are lacking but would greatly benefit this community to prevent progression to greater severity of mental health symptoms.

Prevalence of Possible Mental Disorders in Syrian Refugees Resettling in the United States Screened at Primary Care.

Little is known about mental health problems among newly arrived Syrian refugees in the US. It is important to determine the prevalence of common consequences of exposure to trauma and high stress, and provide needed interventions, as these conditions if untreated, can be detrimental to mental and physical health. Adult Syrian refugees (n = 157, 47.1% women, 52.9% men) were screened at one-month mandatory primary care health visit for Posttraumatic Stress Disorder (PTSD), anxiety and depression using PTSD Checklist, and Hopkins Symptoms Checklist. Prevalence of possible diagnoses was high for PTSD (32.2%), anxiety (40.3%), and depression (47.7%). Possible prevalence of depression and anxiety were higher among women, but there was no gender difference for possible PTSD. We found a high prevalence of possible psychiatric disorders related to trauma and stress among Syrian refugees newly resettled in the US. Due to the high prevalence and feasibility of brief screening tools in primary care facilities, we recommend mental health screening during primary care health visits for resettled Syrian refugees.
