Few studies have investigated the range and severity of insomnia‐related sleep complaints among veterans with posttraumatic stress disorder (PTSD), and the temporal association between insomnia and PTSD severity has yet to be examined. To examine these associations, a large, gender‐balanced cohort of veterans (N = 1,649) of the Iraq and Afghanistan conflicts participated in longitudinal assessments of PTSD and insomnia‐related symptoms over a period of 2.5 years following enrollment (range: 2–4 years).

Background: Major Depressive Disorder (MDD) in adolescence has a high prevalence and risk of disability, but current treatments show limited effectiveness and high drop-out and relapse rates. Although the role of distressing experiences that relate to the development and maintenance of MDD has been recognized for decades, the efficacy of a trauma-focused treatment approach for MDD has hardly been studied.

The focus of this study is the WHO’s mhGAP-Intervention Guide (mhGAP-IG)2.0 (2016), an evidence-based tool and guideline to help detect, diagnose andmanage the most common mental disorders, designed for use by non-specialistsglobally but particularly in low- and middle-income countries. This research is astarting point in tracing the multiple‘doings’of mhGAP-IG–connectingquestions of how it is‘done’and what does it‘do’–to the living histories andwider global mental health assemblages that make the tool possible and shape itsglobal circulation.

Are you feeling anxious? Did you sleep poorly last night? Sleep disruption is a recognized feature of all anxiety disorders. Here, we investigate the basic brain mechanisms underlying the anxiogenic impact of sleep loss. Additionally, we explore whether subtle, societally common reductions in sleep trigger elevated next-day anxiety. Finally, we examine what it is about sleep, physiologically, that provides such an overnight anxiety-reduction benefit.
