A scoping review of psychosocial interventions delivered by non-mental health workers following disaster events.

Individuals exposed to disasters are at high risk of developing mental health conditions, yet the availability of mental health practitioners is often limited. The aim of this scoping review was to examine the quality of the evidence for psychosocial interventions that can be delivered by non-mental health workers in the context of disasters. Searches were performed in PsycInfo, EMBASE, Family & Society Studies Worldwide, CINAHL, Global Health, PubMed, and SCOPUS, from inception through to November 2024, to identify studies of relevance.

Neuroimaging evidence of disturbed self-appraisal in posttraumatic stress disorder: A systematic review.

Background: The experience of self-hood in posttraumatic stress disorder (PTSD) is altered cognitively and somatically. Dysfunctional negative cognitions about the self are a central mechanism of PTSD symptomatology and treatment. However, while higher-order brain models of disturbances in self-appraisal (i.

Reconceptualizing complex posttraumatic stress disorder: A predictive processing framework for mechanisms and intervention.

In this article, we introduce a framework for interpreting Complex Posttraumatic Stress Disorder (C-PTSD) through predictive processing, a neuroscience concept explaining the brain's interpretation and prediction of sensory information. While closely related to PTSD, C-PTSD encompasses additional symptom clusters marked by disturbances in self-organization (DSO), such as negative self-concept, affect dysregulation, and relational difficulties, typically resulting from prolonged traumatic stressors. Our model leverages advances in computational psychiatry and neuroscience, offering a mechanistic explanation for these symptoms by illustrating how prolonged trauma disrupts the brain's predictive processing.

Altered task-related decoupling of the rostral anterior cingulate cortex in depression.

Dysfunctional activity of the rostral anterior cingulate cortex (rACC) - an extensively connected hub region of the default mode network - has been broadly linked to cognitive and affective impairments in depression. However, the nature of aberrant task-related rACC suppression in depression is incompletely understood. In this study, we sought to characterize functional connectivity of rACC activity suppression ('deactivation') - an essential feature of rACC function - during external task engagement in depression.

Improving mental health following multiple disasters in Australia: a randomized controlled trial of the Skills for Life Adjustment and Resilience (SOLAR) programme.

The mental health impacts of climate change-related disasters are significant. However, access to mental health services is often limited by the availability of trained clinicians. Although building local community capability for the mental health response is often prioritised in policy settings, the lack of evidence-based programs is problematic.
