The relationship between posttraumatic stress disorder (PTSD) and high frequency heart rate variability (HF-HRV) was investigated during a resting baseline period and two 4-minute laboratory speech tasks. Participants were 20 women with PTSD and 20 age- and gender-matched controls. Parasympathetic nervous system (PNS) cardiac control was measured as HF-HRV (0.12-0.40 Hz) using power spectrum analysis. Participants with PTSD had significantly greater reductions in HF-HRV during two speech tasks (trauma recall and mental arithmetic) than control. These results suggest that PTSD is related to the magnitude of decrease in parasympathetic cardiac control during stress in women. Health implications of altered PNS activity associated with PTSD deserve further study.

Background: 2022 survey data showed 29% of Veterans utilized Veterans Affairs (VA) paid health care at a non-VA facility, 6% higher than in 2021. Despite an increase in the number of Veterans accessing care in the community via the MISSION Act Community Care Program (CCP), there is limited information on the quality of mental health care delivered to Veterans in these settings. Further, Veterans report barriers to quality care, including poor communication between CCP and VA providers, which can result in negative patient outcomes.

Childhood abuse represents one of the most potent risk factors for the development of psychopathology during childhood, accounting for 30-60% of the risk for onset. While previous studies have separately associated reductions in gray matter volume (GMV) with childhood abuse and internalizing psychopathology (IP), it is unclear whether abuse and IP differ in their structural abnormalities, and which GMV features are related to abuse and IP at the individual level. In a pooled multisite, multi-investigator sample, 246 child and adolescent females between the ages of 8-18 were recruited into studies of interpersonal violence (IPV) and/or IP (i.

Blended care therapy (BCT), which augments live, video-based psychotherapy sessions with asynchronous digital tools, has the potential to increase access to evidence-based treatments for posttraumatic stress disorder (PTSD). However, its effectiveness in diverse, real-world settings is not well-understood. This evaluation aimed to assess clinical outcomes of a BCT program for PTSD symptoms.

Background: Traumatic injury poses significant physical and psychological challenges, often resulting in psychological distress, encompassing symptoms of anxiety, depression and post-traumatic stress. Despite the recognised need for psychological care in trauma rehabilitation, there is limited empirical evidence of effective interventions tailored specifically for individuals with traumatic injuries, leading to a practice-evidence gap.
Objectives: This review aimed to evaluate the effectiveness of psychological and behavioural interventions for reducing psychological distress in adults following traumatic injury.
