More than half of these (>10 million) are children, representing a highly vulnerable population. Most children experience high levels of trauma exposure, including war trauma, as well as substantial migration- and resettlement-related stress. These exposures confer risk for mental health problems, including posttraumatic stress disorder (PTSD), but their relative contributions have not been fully explicated. These effects may be modulated by the developmental timing of trauma and stress exposure: childhood trauma and stress are broadly linked to worse health outcomes across the lifespan, but the developmental specificity of these effects remains uncertain. Refugee children typically experience the trauma leading up to displacement (e.g., civil war) which often lasts for decades, and for some, followed by resettlement. Longitudinal studies that follow children through this process can provide unique insight into how these experiences of trauma, displacement, and resettlement during development impact mechanisms of risk and resilience. They can also elucidate how environmental and physiological factors may modulate the effects of trauma and stress. The present study includes two groups of families (parents and their 7- to 17-year-old children): (1) Syrian and Iraqi refugee families who experienced war-zone trauma before resettling in the United States in ~2016, and (2) Arab immigrant families who did not experience war-zone trauma prior to resettlement in the United States in ~2016. We assessed symptoms of anxiety, depression, and PTSD in refugee and immigrant children and parents. Skin conductance responses, a measure of autonomic response, saliva samples for genetic and epigenetic analyses, and information about social and environmental context, including family structure, resources, and neighborhood quality, were also collected. Refugee participants provided data at three time points spanning ~3 years following resettlement in the United States: Wave 1, within 1 month of resettlement, Wave 2, 12-24 months post resettlement, and Wave 3 planned for 24-36 months resettlement. Immigrant participants will provide data once, within 3-5 years after immigration, matching the age of Wave 1. This comparison group enables us to compare mental health and biomarkers between refugees and immigrants. Results of these comparative analyses will provide insight into the impact of war trauma versus other types of trauma and adversity on biomarkers of child mental health outcomes. Results from the longitudinal analyses will address refugee mental health trajectories over time, and, in children, across development. Initial data from Wave 1 showed high levels of anxiety in refugee children, as well as high levels of PTSD symptoms and anxiety in their parents. Together, results from these comparative and longitudinal analyses will provide insight into multiple aspects of trauma and stress exposure in refugees an","PeriodicalId":73912,"journal":{"name":"Journal of psychiatry and brain science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8009534/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25537614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ideal foci for suicide prevention interventions are risk factors that are malleable, dynamic, and proximal. Studies consistently identify poor sleep health as a risk factor for suicidal thoughts, attempts, and death. Herein, we assert that sleep health may therefore be a promising target for youth in general, and given racial disparities in sleep health, for Black youth in particular. Although efficacious sleep and circadian-focused interventions exist, data suggest poorer treatment response among racially and ethnically minoritized youth, possibly due to inadequate consideration of sleep health barriers specific to Black youth. The application of health-equity informed implementation science methods is needed to establish the feasibility and acceptability of a sleep intervention for Black youth at-risk for suicide. Such an approach may hold significant potential to improve sleep, ameliorate distress, and reduce suicide risk, while also enhancing access and uptake among Black youth.","PeriodicalId":73912,"journal":{"name":"Journal of psychiatry and brain science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67610593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early CHR research largely focused on validating clinical interviews for detecting at-risk individuals; however, this approach has limitations related to: (1) specificity (i.e., only 20% of CHR individuals convert to psychosis) and (2) the expertise and training needed to administer these interviews is limited. The purpose of our study is to develop the computerized assessment of psychosis risk (CAPR) battery, consisting of behavioral tasks that require minimal training to administer, can be administered online, and are tied to the neurobiological systems and computational mechanisms implicated in psychosis. The aims of our study are as follows: (1A) to develop a psychosis-risk calculator through the application of machine learning (ML) methods to the measures from the CAPR battery, (1B) evaluate group differences on the risk calculator score and test the hypothesis that the risk calculator score of the CHR group will differ from help-seeking and healthy controls, (1C) evaluate how baseline CAPR battery performance relates to symptomatic outcome two years later (i.e., conversion and symptomatic worsening). These aims will be explored in 500 CHR participants, 500 help-seeking individuals, and 500 healthy controls across the study sites.

Suicidal behavior has been linked to neurobiological, neurocognitive and behavioral factors; however, integrative, multi-modal studies are rare. Furthermore, prospective studies, crucial to understanding future risk factors, have focused on a single predictor and a single outcome, implying that suicidal behavior is homogeneous. But recent research shows suicidal behavior is complex and heterogeneous, with the possible existence of subtypes. The present report describes a project testing a model that posits two putative subtypes, using a prospective, multi-model design. The subtypes differ in regard to the patterns of suicidal ideation and underlying mechanisms. One hundred subjects diagnosed with a Major Depressive episode, half of whom have attempted suicide in the past, are enrolled and followed for two years, notably the highest risk period for suicidal behavior. Baseline assessments include a clinical assessment, neurocognitive and behavioral tasks, Ecological Momentary Assessments (EMA), PET imaging, and a cognitive emotion regulation task in the MRI scanner.
