The Link between Posttraumatic Stress Disorder and Functionality among United States Military Service Members Psychiatrically Hospitalized Following a Suicide Crisis

Unveiling temporal dynamics of PTSD and its functional impairments: A longitudinal study in UK healthcare workers

PTSD has been associated with negative long-term consequences, including social and occupational impairments. Yet, a nuanced understanding of the interplay between PTSD symptoms and distinct domains of impairments on a short-term basis (weeks/ months) at the within-person level remains underexplored. In a large sample (nwave 1 = 1096, nwave 7 = 304) of UK healthcare workers assessed across seven assessment waves during the COVID-19 pandemic (spaced 6 weeks apart), we employed exploratory graphical vector autoregression models (GVAR) models to discern within-person temporal (across time) and contemporaneous (within same time window) dynamics between PTSD symptoms and functional impairment domains. The contemporaneous network highlighted strong co-occurrences between different symptoms and impairments. The temporal network revealed a mutually reinforcing cycle between intrusion and avoidance symptoms. Intrusion symptoms showed the highest out-strength (i.e., most predictive symptom), predicting avoidance symptoms, elevated sense of current threat, and various functional impairments. Avoidance symptoms, elevated after increased levels of intrusions, predicted work impairments that in turn were associated with difficulties in fulfilling other obligations. Our findings underscore the dynamics between perceived threat and intrusions, and the role intrusions may play in predicting a cascade of adverse effects. Targeted interventions aimed at mitigating intrusions may disrupt this negative cycle.

DSM-5-Based ASD Models: Assessing the Latent Structural Relations with Functionality in War-Exposed Individuals

There is a dearth of studies investigating the latent structure of Acute Stress Disorder (ASD) following the changes in the fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). To date, there is no consensus on the best representation of ASD. This study addressed this gap by examining four latent ASD models in a sample of war-exposed individuals (N = 424). Investigation on the relationship of the best-fitting model to functionality in the latent level was also conducted. The five-factor model, composed of intrusion, avoidance, numbing, dysphoric arousal, and anxious arousal factors, yielded the best-fitting model. Latent associations between the factors of the model and functionality suggest that symptoms of functionality do not significantly affect the factor structure of ASD. These findings have implications for understanding the underlying mechanism of ASD and can inform the development of more nuanced trauma-related interventions, particularly addressing ASD symptoms and functionality separately.

Post-traumatic stress disorder and subthreshold post-traumatic stress disorder in recent male asylum seekers: An expected but overlooked "European" epidemic

The literature shows an increased risk for post-traumatic stress disorder (PTSD) among illegal migrants. We aimed to estimate the prevalence of PTSD, subthreshold PTSD, the degree of disability, and differences in sociodemographic and anamnestic characteristics associated with these clinical conditions in a sample of newly arrived migrants. Two hundred male asylum seekers from West sub-Saharan Africa were evaluated for traumatic life events, PTSD symptoms, and disability through the Life Events Checklist for DSM-5 (LEC-5), the Primary Care PTSD Screen, the PTSD Checklist for DSM-5, and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). The current prevalence of PTSD and subthreshold PTSD was 9.5% and 12.0%, respectively. PTSD and subthreshold PTSD subgroups presented higher WHODAS 2.0 scores and LEC-5 events, an over-representation of individuals with childhood adversities and an excess of premigration psychiatric contacts unrelated to PTSD spectrum disorders and peri-migration offences. Witnessing a traumatic event and disability in understanding and communication predicted both the presence of PTSD symptoms and PTSD status. PTSD spectrum disorders should be considered among the clinical emergencies associated with asylum seeker condition, and targeted interventions also involving the host citizens should be predisposed.

Sleep Disturbances and Suicidality in Posttraumatic Stress Disorder: An Overview of the Literature

A causal relationship between sleep disturbances and suicidal behavior has been previously reported. Insomnia and nightmares are considered as hallmarks of posttraumatic stress disorder (PTSD). In addition, patients with PTSD have an increased risk for suicidality. The present article gives an overview about the existing literature on the relationship between sleep disturbances and suicidality in the context of PTSD. It aims to demonstrate that diagnosing and treating sleep problems as still underestimated target symptoms may provide preventive strategies with respect to suicidality. However, heterogeneous study designs, different samples and diverse outcome parameters hinder a direct comparison of studies and a causal relationship cannot be shown. More research is necessary to clarify this complex relationship and to tackle the value of treatment of sleep disturbances for suicide prevention in PTSD.
