Transforming Trauma Care

This study evaluates the implementation and clinical effectiveness of the Trauma Resilience and Recovery Program (TRRP 2.0), a technology-enhanced behavioral health intervention designed for trauma center patients. TRRP 2.0 integrates screening, monitoring, and referral services for posttraumatic stress disorder (PTSD), depression, and substance use disorder (SUD). The study uses a two-phase design across two trauma centers: a usual care phase followed by implementation of TRRP 2.0. A total of 300 adult trauma patients will be recruited and followed for 3 months to assess behavioral health service utilization and clinical outcomes.

A Digital Cognitive Intervention for Intrusive Memories After Trauma

Intrusive traumatic memories frequently trigger severe distress and psychological disorders such as post-traumatic stress disorder (PTSD). Traditional therapies require explicit trauma recall, which often causes severe patient distress and may lead to treatment avoidance. To address this, our study introduces a less aversive intervention that combines unconscious visual processing with bilateral eye movements to reduce intrusive traumatic memories. Utilizing a randomized, three-arm design, we will compare standardized trauma-related images, patient-provided images, and neutral images, all paired with bilateral eye movements. We plan to recruit participants who have experienced severe trauma and report at least 5 intrusive memories per week, with a target final sample of 40 participants per arm. The primary outcome is the frequency of intrusive memories. Secondary and additional outcomes include PTSD severity, as measured by the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), the PTSD Checklist for DSM-5 (PCL-5), and the Impact of Event Scale (IES), as well as depression, anxiety, borderline symptoms, functional improvement, subjective intervention distress, and dropout rates.

Effect of Psilocybin and Structured Integrated Reframing Therapy on Gut-Brain Axis Biomarkers and Depression in Major Depressive Disorder

Trauma-related Major Depressive Disorder (MDD) is frequently associated with poor response to conventional antidepressants, persistent psychological distress, and alterations in gut-brain axis function. Existing assessment tools primarily diagnose depression or PTSD but provide limited guidance for integrated clinical management. This study aims to develop and validate the Trauma Anxiety Depression Emotion (TADE) management tool while simultaneously evaluating the effectiveness of psilocybin-assisted Structured Integrated Reframing Therapy (SIRT) in improving clinical and biological outcomes. This prospective, four-arm randomized controlled trial will compare conventional therapy, psilocybin therapy, SIRT, and psilocybin-assisted SIRT. Participants will undergo assessment using the newly developed TADE tool together with established psychometric scales including HAM-D, PCL-5, and GAD-7. Biological outcomes will include serum gut-brain axis and inflammatory biomarkers, including Short-Chain Fatty Acids (SCFAs), Interleukin-6 (IL-6), Interleukin-10 (IL-10), Zonulin, Occludin, and Glial Cell Line-Derived Neurotrophic Factor (GDNF). Assessments will be performed at baseline, during treatment, and at 12-week follow-up. The study aims to determine whether combining psilocybin with SIRT provides superior clinical improvement and favorable biological changes compared with either intervention alone while establishing the validity and clinical utility of the TADE management tool.

Examining Intranasal Oxytocin Augmentation of Brief Couples Therapy for Veterans With PTSD

Leveraging veterans' intimate relationships during treatment for posttraumatic stress disorder (PTSD) has the potential to concurrently improve PTSD symptoms and relationship quality. Brief Cognitive-Behavioral Conjoint Therapy (bCBCT) is a manualized treatment designed to simultaneously improve PTSD and relationship functioning for couples in which one partner has PTSD. Although efficacious in improving PTSD, the effects of CBCT on relationship satisfaction are small, especially among Veterans. Pharmacological augmentation of bCBCT with intranasal oxytocin, a neurohormone that influences mechanisms of trauma recovery and social behavior, may help improve the efficacy of bCBCT. The purpose of this randomized placebo-controlled trial is to compare the clinical and functional outcomes of bCBCT augmented with intranasal oxytocin (bCBCT + OT) versus bCBCT plus placebo (bCBCT + PL). The investigators will also explore potential mechanisms of action: communication, empathy, and trust.

Trauma-Focused Cognitive Behavioral Therapy in Unaccompanied Refugee Minors With PTSD in Greece: An RCT

This single-blinded, multicentered, randomized controlled trial aims to evaluate the effectiveness of Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) compared to Treatment-as-Usual (TAU) in reducing post-traumatic stress symptoms among unaccompanied refugee minors (UAMs) residing in accommodation centers and Supported Independent Living (SIL) programs in Greece. Participants aged 15-18 will be randomly assigned to either a TF-CBT intervention group or a TAU control group. The intervention will be delivered by trained psychologists under supervision and culturally adapted to the Greek refugee context. Assessments will occur at baseline, post-intervention, and three months later, using standardized psychometric tools. Secondary outcomes include changes in comorbid psychiatric symptoms (depression, anxiety, somatic symptoms), emotional and behavioral difficulties, and quality of life. The study also investigates potential moderators of treatment response such as age, gender, trauma history, and psychiatric comorbidity.
