Grappling With Trauma: Brazilian Jiu-Jitsu for First Responders

This study explores whether participating in an 8-week Brazilian Jiu-Jitsu (BJJ) program is linked to changes in trauma-related symptoms among first responders. Many first responders experience ongoing stress or exposure to traumatic events, and some prefer physical, movement-based activities rather than traditional clinical services to support their well-being. In this study, participants will attend BJJ classes one to two times per week for eight weeks. They will also complete short daily and weekly questionnaires about mood, stress, and well-being, write brief weekly reflections, and participate in a one-on-one interview after the program. The study aims to understand both symptom patterns and participants' personal experiences with emotional regulation and overall wellness during the program. This study does not provide mental health treatment and will not diagnose or treat PTSD. Instead, it examines whether BJJ, as a non-clinical physical activity, may offer supportive benefits for first responders.

PTSD Risk Prediction Model for EICU Survivors

Brief Title: PTSD Risk Prediction Model for EICU Survivors Official Title: Development and Validation of a Risk Prediction Model for Post-Discharge Post-Traumatic Stress Disorder in Emergency Department-Admitted EICU Survivors Study Type: Observational Brief Summary: This study aims to develop and validate a risk prediction model for post-traumatic stress disorder (PTSD) at 1 month after hospital discharge in adult survivors of emergency intensive care unit (EICU) care. PTSD is a common and serious psychological condition that can occur after a life-threatening medical event. Many EICU survivors experience persistent stress responses, sleep problems, avoidance behaviors, and difficulty returning to normal life after leaving the hospital. This prospective observational cohort study will enroll approximately 800 adult patients who are admitted to the EICU through the emergency department at Sir Run Run Shaw Hospital and other participating centers. Participants will be followed up at 1 month after EICU discharge to complete the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5), a diagnostic interview for PTSD. Clinical data collected during the emergency department stay and EICU course-including vital signs, laboratory tests, treatments, and severity of illness-will be used to build statistical models to predict which patients are most likely to develop PTSD. The study does not involve any experimental treatments or additional procedures beyond routine clinical care. Results from this study may help healthcare providers identify high-risk patients early and provide timely psychological support and follow-up care. Detailed Description: Background: Advances in critical care medicine have enabled an increasing number of emergency critical care patients to survive to ICU or hospital discharge. However, a substantial proportion of survivors experience persistent psychological sequelae, including post-traumatic stress disorder (PTSD), which significantly impairs quality of life. Patients admitted to the EICU via the emergency department are exposed to multiple stressors during the early phase-sudden life-threatening illness, pain, hypoxia, altered consciousness, mechanical ventilation, sedation, and separation from family-which may serve as important risk factors for subsequent PTSD. Objectives: To develop and validate a risk prediction model for predicting 1-month post-discharge PTSD in adult patients admitted to the EICU via the emergency department. Study Design: This is a prospective observational cohort study conducted at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine (coordinating center) and multiple other centers. Study Population: Adult patients (≥18 years) admitted to the emergency department and subsequently transferred to the EICU, with an ICU length of stay of at least 24 hours, who survive to EICU discharge and have a Glasgow Coma Scale score ≥12 at discharge or follow-up. Sample Size: Approximately 800 patients (approximately 200 per center if 4 centers participate), calculated based on an estimated 25% PTSD prevalence at 1 month post-discharge, with 6-8 candidate predictors, expected Nagelkerke R² of 0.15, target shrinkage of 0.90, and accounting for 15%-20% attrition. Data Collection: All variables are routine clinical observation and laboratory parameters, categorized into six domains: (1) baseline susceptibility variables (demographics, social support, psychiatric history, trauma history, prior ICU admission, substance use, chronic disease burden); (2) emergency admission phase variables (mode of admission, severity, vital signs, etiology, early labs, emergency treatments); (3) first 24 hours in EICU variables (severity scores, organ support, sedation/analgesia, neurological status, nursing exposures, early complications); (4) cumulative EICU exposure variables (duration of organ support, cumulative sedation/analgesia, mechanical ventilation duration, physical restraints, delirium, infections, major complications); (5) disease process and treatment-related variables (severe infection, respiratory failure, AKI, ARDS, transfusion, emergency surgery, intubation, CPR); and (6) 1-month post-discharge follow-up (CAPS-5 diagnostic PTSD assessment). Primary Outcome Measure: CAPS-5-diagnosed PTSD at 1 month post-EICU discharge. Statistical Analysis: Three types of prediction models will be developed: (1) an early model using variables available within the first 6 hours from emergency department presentation to EICU admission; (2) a discharge-updated model adding ICU exposure, treatment interventions, complications, and pre-discharge information; and (3) a dynamic digital model further adding post-discharge electronic follow-up and digital phenotyping data. Candidate modeling approaches include logistic regression, LASSO/ElasticNet penalized regression, random forest, gradient boosting trees, XGBoost/LightGBM, and support vector machines. Model performance will be evaluated for di

Prognosis of Epilepsy With Post-traumatic Stress Disorder and Surgery

Why is this study being conducted? For people with drug-resistant focal epilepsy, surgery, to remove the part of the brain where seizures start, is currently the most effective treatment. In many people, especially those with temporal lobe epilepsy, surgery can stop seizures completely and improve quality of life. However, doctors usually predict the chances of surgical success using brain scans and other neurological tests, while the possible influence of psychological and social factors remains less well understood. Mental health is an important part of overall health. People living with epilepsy are more likely than the general population to experience anxiety, depression, and post-traumatic stress disorder (PTSD). PTSD can develop after experiencing traumatic events and may affect emotional well-being, daily activities, relationships, and physical health. Some studies suggest that PTSD may affect brain networks involved in epilepsy. This raises an important question: could PTSD influence the success of epilepsy surgery? We hypothesize that PTSD and other psychological or social factors may affect surgical outcomes and recovery after surgery. At present, there is limited evidence available to answer this question. What is the aim of the study? The main objective of this study is to determine whether PTSD affects the success of epilepsy surgery two years after the operation. The study also aims to: * Describe the medical, psychological, and social characteristics of people undergoing epilepsy surgery and estimate how common traumatic experiences and PTSD are in this population; * Assess changes in PTSD symptoms, anxiety, depression, quality of life, social vulnerability, and patient satisfaction before and after surgery; * Identify biological, psychological, and social factors associated with successful surgical outcomes. Rather than focusing only on seizure control, this study aims to improve understanding of the factors that contribute to recovery, quality of life, and long-term well-being after epilepsy surgery. The findings may help healthcare professionals provide more personalized support before and after surgery. Who can take part? Between September 2026 and September 2028, the study will recruit 42 adults with drug-resistant focal epilepsy who are being evaluated for resective epilepsy surgery at Timone University Hospital in Marseille, France. What does participation involve? Participants will join the study approximately three months before surgery and will be followed for two years after the operation. During routine pre-operative and post-operative follow-up visits, participants will complete validated self-report questionnaires about: * Traumatic experiences and PTSD symptoms; * Anxiety and depression; * Quality of life; * Social vulnerability; * Satisfaction with surgery. Participants whose questionnaire results suggest possible PTSD will be offered a routine psychiatric assessment to confirm the diagnosis. Based on these assessments, participants will be classified into one of two groups: people with PTSD and people without PTSD. The study will also use clinical information routinely collected as part of epilepsy care, including brain imaging, electroencephalography (EEG), and neuropsychological assessments. What are the expected benefits of this research? This study may improve understanding of how psychological and social factors influence epilepsy surgery outcomes. The results may help healthcare professionals better identify patients who could benefit from additional support before and after surgery. In the future, the findings could contribute to the development of more personalized care pathways, including advanced practice nursing follow-up, improved mental health screening, and targeted support to enhance seizure outcomes, quality of life, emotional well-being, and patient satisfaction after epilepsy surgery

Evaluating Treatments for Suicidal Veterans With PTSD

Posttraumatic Stress Disorder (PTSD) is a significant driver of suicide risk among Veterans, but there is a critical knowledge gap about how to treat PTSD among people at elevated risk for suicide. Although evidence-based treatments for PTSD reduce suicide risk, Veterans at high risk for suicidal behavior rarely receive these potentially life-saving treatments. Prior research suggests that a treatment that combines Dialectical Behavior Therapy (DBT) with the DBT Prolonged Exposure protocol (DBT PE) for PTSD improves both PTSD and suicide-related outcomes. This study will evaluate whether DBT + DBT PE improves these outcomes more than Prolonged Exposure plus suicide risk management, the gold standard VA care for this population. The proposed study will also examine factors that make it easier and harder to implement these treatments in VA settings. The results will help to inform treatment guidelines for this high-priority Veteran population.

Two-Year Follow-up Study on Children Exposed to Trauma

In our clinic, we plan to conduct research two years after the initial assessments (January-April 2024 and one year ago, January-June 2025) of children and adolescents with trauma exposure who were evaluated as part of their thesis studies. The aim is to re-evaluate these individuals to determine how many continue to receive a PTSD diagnosis, how many receive a diagnosis of K-PTSD, and what factors are associated with these changes. This research aims to contribute to the literature on the long-term effects of trauma exposure.

Developing and Testing Innovative Care Pathways for Screening and Treatment of OUD/PTSD in Jails

Opioid overdose is the leading cause of death among people recently released from incarceration. Recent evidence also shows a rise in stimulant use among justice-involved populations, as well as growing rates of concurrent opioid and stimulant use. Yet, while there is growing research on opioid use disorder (OUD), stimulant use disorder (STUD), and substance use treatment in jails and prisons, studies find that few people who are referred to community substance use treatment actually initiate treatment after release. But, emerging research suggests that therapy for posttraumatic stress disorder (PTSD), a common and deleterious OUD and STUD comorbidity, could profoundly increase the likelihood of engagement with substance use treatment; however, this has not been tested in jails, and acceptable, appropriate, and feasible ways to identify and link people with probable PTSD and OUD/STUD in this setting to treatment are required to be able to examine this possibility. Therefore, this 4-year R33 aims to 1) describe engagement in and examine the implementation outcomes of an innovative approach to identifying and referring people with probable PTSD and OUD/STUD to needed treatment services and 2) the effectiveness and implementation outcomes of two competing models of subsequent trauma-focused therapy initiation timing (i.e., immediate initiation of therapy vs initiation upon community reentry) among people who demonstrate need for OUD/STUD services and who accept referral. To address Aim 1, the investigators will assess the implementation context for and subsequently implement a screening, brief intervention, and referral to treatment model that was adapted to identify and address the substance use and mental health needs of adults with probable PTSD and OUD/STUD in the jail setting (SBIRT-J) in the Pulaski County Regional Detention Facility; the investigators will describe engagement in and examine the implementation outcomes of the SBIRT-J model via a summative evaluation guided by the Consolidated Framework for Implementation Research. Specifically, there will be a survey and interview jail stakeholders (e.g., jail leadership, officers) to understand perceptions of the acceptability, appropriateness, and feasibility of the SBIRT-J model as well as SBIRT-J implementation determinants (i.e., barriers and facilitators), and use administrative data to understand the degree to which SBIRT-J is adopted during active enrollment in the R33 Aim 2 research trial and sustained in the 6 months after enrollment end. Fidelity to the SBIRT-J model will also be monitored and reported. To address Aim 2, the investigators will conduct a patient-randomized Hybrid type I implementation-effectiveness trial in which adults who are identified as having probable PTSD and OUD/STUD through the SBIRT-J model and who consent to participate in the trial are randomly assigned to either immediate initiation of therapy for PTSD in jail or initiation of PTSD therapy upon release. The primary effectiveness outcome will be post-release substance use treatment initiation by 6-months post-release from jail; secondary and exploratory outcomes will include substance use treatment readiness and retention, OUD/STUD severity, PTSD symptoms, victimization, overdose, and additional drug use. Participants in the effectiveness portion of the trial (N = 338; \~50% female) will be enrolled from the largest jail in Arkansas. Jail stakeholders will also be enrolled to provide implementation-related data. The overall goal is to translate research to practice to increase the provision of high-quality care for justice-involved persons with probable PTSD and OUD/STUD. Indeed, this study will be the first trial of a treatment for PTSD in jails as a method for improving OUD/STUD outcomes, providing foundational information on PTSD as a novel intervention target for meeting the needs of a particularly vulnerable population and providing the implementation data to inform rapid scale-up, if effective.

Effects of the Integrated Grief Therapy on Psychological Resilience, Post-Traumatic Growth, Traumatic Stress, and Grief Processes in Earthquake Survivors

This study evaluates the effectiveness of an Integrated Grief Therapy (IGT) group program for adults affected by the February 6, 2023 earthquake in Türkiye. Many earthquake survivors experience psychological difficulties such as traumatic stress, grief, and reduced resilience after losing loved ones, homes, and a sense of safety. This study aims to determine whether a structured group-based therapy program can help improve psychological well-being and reduce distress. A total of 190 adult participants who experienced the earthquake were included in the study. Participants were randomly assigned to either an experimental group or a waitlist control group. The experimental group participated in an 8-session Integrated Grief Therapy program delivered face-to-face by trained mental health professionals. The program included psychoeducation about grief, emotional expression, cognitive and behavioral coping strategies, and activities designed to support meaning-making and adaptation after loss. The control group continued to receive routine psychosocial support services available in the community but did not participate in the structured therapy during the study period. All participants completed standardized psychological assessments before and after the intervention. These assessments measured psychological resilience, post-traumatic growth, grief-related difficulties, and traumatic stress symptoms. The study aims to determine whether participants who receive the Integrated Grief Therapy program show greater improvements in resilience and post-traumatic growth, and greater reductions in traumatic stress and grief symptoms, compared to those who do not receive the intervention during the same period. The findings from this study may help inform the development of effective, scalable mental health interventions for individuals affected by large-scale disasters.

Post-natal Post-traumatic Stress: Impact of an Early Dyadic Intervention Though Interaction Guidance Therapy on Maternal Sensitivity and Reduction of Maternal Stress

The aim of this study is to assess if an early therapeutic management focused on the mother-baby interaction using Interaction Guidance Therapy (IGT) with video feedback, brings an improvement of the maternal sensitivity in the interaction but also a decrease of the post-traumatic maternal symptoms. Post Natal Post traumatic stress is known as a disorder that impaired maternal mental health but also development of motherhood and the construction of the bond to the baby through interactive disturbances. The investigators will screen, among women who had a traumatic perception of an event related to the pregnancy or the childbirth, those who still present posttraumatic stress symptoms at 4 weeks post-partum. Four weeks from the traumatic event is the minimum delay to qualify a PTSD. After randomization IGT versus Treatment As Usual (TAU), the investigators planned an early therapeutic intervention, 3 sessions at 8, 10 and 12 weeks of post-partum. The investigators will assess the effect of the IGT on Maternal sensitivity and on the intensity of post-traumatic stress symptoms at 3 month post-partum and 1year.

Tetris Intervention Following Subliminal Reactivation for Intrusive Memories

Post-Traumatic Stress Disorder (PTSD) is characterized by recurrent, intrusive memories of traumatic events that cause significant distress and functional impairment. Although trauma-focused treatments are effective, they typically require deliberate recollection of traumatic experiences, which can be distressing and may contribute to treatment avoidance or dropout. In previous experimental studies conducted with healthy participants, we demonstrated that unconscious reactivation of trauma-related cues, followed-after a brief delay corresponding to the memory reconsolidation window-by a visuospatial interference task (Tetris gameplay), reduced the frequency and emotional intensity of intrusive memories. These findings suggest that memory representations may be modifiable during reconsolidation without requiring conscious recall. Building on this work, the present randomized controlled trial (RCT) aims to evaluate the clinical efficacy and tolerability of this reconsolidation-based intervention in trauma-exposed individuals experiencing five or more intrusive memories per week.

Ketamine for Pain, Opioid Use, and Mental Health in Orthopedic Trauma Patients

The goal of this clinical trial is to learn if ketamine, given during surgery, can help improve recovery for adults with serious orthopedic trauma. The study will test whether ketamine reduces pain, lowers the need for opioids, and improves mental health outcomes like depression and post-traumatic stress disorder (PTSD). The main questions it aims to answer are: Does ketamine reduce pain after surgery compared to standard anesthesia? Does ketamine reduce the amount of opioids patients need for pain control? Does ketamine improve symptoms of depression and PTSD after orthopedic trauma? Researchers will compare patients who receive ketamine during surgery with those who receive standard anesthesia without ketamine to see if ketamine helps improve both physical and psychological recovery. Participants will: Be randomly assigned to receive either a single dose of ketamine or standard anesthesia during surgery. Report their pain using a simple pain scale (Visual Analog Scale, VAS). Complete short surveys about mood and mental health (PHQ-9 for depression and PCL-5 for PTSD) at several time points after surgery. Allow the research team to review their electronic medical records to measure opioid prescriptions during recovery. Attend follow-up visits in clinic or by secure telehealth (e.g., Zoom) at 1-7 days, 2-3 weeks, 6 weeks, 3 months, and 6 months after surgery

EMDR Integrative Group Protocol and Individual Treatment for Patients With Cancer: A Pilot Study

The main aim of the present process-outcome study is to evaluate the feasibility and the effects of an EMDR-IGTP-OTS group intervention on a sample of people with cancer, by using a process-outcome study design, with repeated measures.

Blended Trauma-Focused Cognitive Behavioral Therapy With Compassion

Brief Summary The goal of this clinical trial is to evaluate the feasibility and acceptability of a blended (mHealth) Trauma-Focused Cognitive Behavioral Therapy with Compassion (bTF-CBT-C) for adolescents with post-traumatic stress disorder (PTSD) in routine child and adolescent psychiatric services in northern Sweden. The main questions it aims to answer are: * Is bTF-CBT-C feasible to deliver in routine care, as indicated by recruitment, retention, adherence to sessions and app modules, data completeness, and adverse events? * Is bTF-CBT-C acceptable to adolescents, caregivers, and therapists, as indicated by satisfaction, therapeutic alliance, digital treatment evaluation, and qualitative interviews? Researchers will compare bTF-CBT-C to standard TF-CBT to explore whether the blended format shows similar or potentially improved patterns in clinical outcomes (e.g., PTSD symptoms, emotion regulation, and self-compassion) and to estimate variability needed to plan a future non-inferiority trial. Participants will: * Complete eligibility screening and baseline assessments, including a diagnostic interview for PTSD. * Be randomized to either bTF-CBT-C or standard TF-CBT. * Receive trauma-focused treatment over time, with caregiver involvement in both groups. * In the bTF-CBT-C group, use a secure mobile app for stabilization modules and exercises, together with therapist-led video sessions and selected in-person meetings. * Complete assessments at baseline, after stabilization, post-treatment, and at 6-month follow-up, and provide feedback about their experiences (questionnaires and interviews).

Sleep Disturbances in Children and Adolescents With Post-traumatic Stress Disorder (PTSD): a Randomized Double-blind Placebo-controlled Trial to Investigate the Efficacy of Pediatric Prolonged-release Melatonin

Among the most sensitive and persistent symptoms of post-traumatic stress disorder (PTSD) in children are sleep disturbances in the insomnia spectrum (sleep onset disturbances, fragmented sleep with multiple nocturnal awakening, early morning awakening) as well as nightmares, affecting over 50% of children and adolescents one year after the initial trauma. There are currently no gold standard treatments or pharmacological treatment recommendations specifically for these sleep disturbances in children and adolescents with PTSD, despite the fact that they have a significant effect on daytime functioning and overall mental health of the children and their families. If not treated appropriately, these sleep disturbances in children and adolescents persist over time, and further increase anxiety in children. Sleep disturbances associated with PTSD are predictive of the persistence and long-term outcome of PTSD itself and associated depressive symptomatology, and of a decreased response rate to cognitive-behavioral psychotherapy for PTSD. We have previously shown in an international multicenter study that pediatric prolonged release melatonin (PedPRM) has high beneficial effects on sleep disturbances of the insomnia spectrum in children ages 2-17.5 years with autism spectrum disorder, and consecutive positive effects on children's daytime behavior, including anxiety and depressive symptomatology. Its benefit-risk ratio has proven to be excellent over a 2-year follow-up. Beyond its therapeutic benefit on mental health through improvement of sleep, melatonin may have a direct effect on reducing anxiety levels and overall daytime functioning in children, as well as sleep and daytime function in caregivers. Our study will be the first randomized controlled trial investigating the efficacy of prolonged release melatonin on sleep disturbances in children and adolescents with PTSD, as well as on PTSD symptoms, associated daytime function and overall mental health in these children and their caregivers.

A Computer Game for Postpartum Mental Health After Emergency Cesarean Birth

This study aims to explore whether playing the computer game Tetris can reduce PTSD symptoms in women who have undergone emergency caesarean births. Additionally, as a feasibility study, it seeks to provide essential data and insights that will guide the design and implementation of future larger-scale RCTs examining the effects of Tetris in this context. The specific objectives are to explore: 1. Whether playing Tetris within 24 hours of an emergency C-section help to reduce symptoms of PTSD. 2. Clinical feasibility and acceptability for an intervention (ie. game Tetris) immediately after a cesarean section. 3. Issues arising from the research design, including requitement and sample size. Participants in the intervention group will play Tetris for at least 10 minutes, but no more than 15 minutes within 24 hours of a C-section. For outcomes, all participants will complete the questionnaires on the fifth day after the C-section and one month postpartum.

Accelerated Neuromodulation for Concurrent Post-Traumatic Stress Disorder (PTSD) & Chronic Pain in Veterans

The ANCHOR study is testing a novel, non-invasive brain stimulation program designed specifically for Veterans experiencing concurrent post-traumatic stress disorder (PTSD) and chronic pain. These conditions often occur together and can greatly impact daily life. Current treatments options for PTSD and chronic pain are limited, may come with severe side-effects, and often take weeks if not months to see results. In this study, participants will receive an intensive one-week course of intermittent theta burst stimulation (iTBS), a Health Canada-approved technology already used for depression. In this study, it is being tested for its potential to reduce both PTSD and chronic pain symptoms. This clinical trial will recruit 30 Veterans, all of whom will receive the active treatment (there is no placebo). Participants will receive 5-6 sessions of iTBS per day (each treatment lasts approximately 3 minutes) over a period of 5 days (one week total duration). Researchers will track changes in PTSD symptoms, chronic pain, mood, anxiety, daily functioning, and cognitive performance at 4 time points: baseline (before treatment), at the end of treatment ( end of week 1), and at 2 follow-up assessments (3 weeks and 6 weeks after the end of treatment). The goal of this study is to determine whether this unique brain stimulation program is able to treat concurrent PTSD and chronic pain in Canadian Veterans. This study also aims to lay the groundwork for larger trials that could expand access to innovative treatments for the Veteran community.

Early Intervention After Traumatic Exposure in Children and Adolescents

The aim of this interventional research is to evaluate the effectiveness of CFTSI in reducing post-traumatic symptoms measured using the CPC, child version, at the end of CFTSI treatment in children and adolescents aged between 7 and 17 years, exposed to an ET in the last 3 months. The main question(s) it aims to answer \[is/are\]: * CFTSI reduces posttraumatic Child Posttraumatic Stress Checklist (CPC) scores in children exposed to ET, both immediatly after completion of the CFTSI and at 3 months after completion. * CFTSI reduces post-traumatic scores in parents on the PTSD Checklist for DSM5 (PCL), both immediatly after completion of the CFTSI and at 3 months after completion. * researchers will compare the reduction in post-traumatic symptoms between participants receiving CFTSI and those receiving non-specific child-centred psychological support. Symptoms will be assessed using the PCL in parents and the CPC in children and adolescents, immediately after completion of the program and again at 3 months after completion. The participants will be randomised into two groups, one that will undergo CFTSI and one that will undergo supportive psychological therapy. Each participant will receive one session per week over five weeks, and possibly 1 to 3 additional sessions if necessary over a further three weeks, and will then be reviewed three months later.

NightWare and Cardiovascular Health in Veterans With PTSD

The purpose of this study is to learn more about the effectiveness of a prescription wrist-wearable device called NightWare (NW) on improving sleep in Veterans with nightmares related to posttraumatic stress disorder (PTSD). The investigators also want to learn whether it improves cardiovascular health among this population.

Attachment and Post-Traumatic Stress Disorder in Military Personnel: Characterization of the French Military Population, Exploration of Biopsychosocial Factors, and Study of the Impact of Security Priming on Emotional Contagion Capacities

Post-traumatic stress disorder (PTSD) is a pathology that impairs the quality of life of sufferers. In military personnel, it can lead to military incapacity. This psychopathology is characterized by confrontation with one or more traumatic events in the individual's life history. Symptoms include cognitive and mood disorders, avoidance, hyperactivation (hypervigilance and anger) and intrusions (flashbacks and nightmares). Studies show that the prevalence of PTSD in military personnel fluctuates considerably from one situation to another (pre-deployment/post-deployment, etc.). In these at-risk populations, the often more complex PTSD clinic may also account for the heterogeneity of prevalences observed. Nevertheless, PTSD tends to become chronic in military personnel, making it particularly difficult to return to a "previous" state. In French casualties, beyond the symptoms already mentioned, complaints focus on difficulties in social interaction situations involving others in social life (attachment style to others) and in everyday life (public transport, supermarket shopping, social interactions, presence of crowds...). In the context of post-traumatic stress disorder, we would like to explore the processes of social cognition that enable people to interact in their environment, in relation to biological, psychosocial and physiological variables that may constitute risk or maintenance factors for the pathology.

Follow-Up Study on Children Exposed to Trauma

As far as it is known, there is no longitudinal study in Turkey investigating the follow-up and treatment of children and adolescents exposed to trauma. This study is planned to reassess children and adolescents with trauma exposure who were evaluated in Istanbul Faculty of Medicine Child Psychiatry outpatient clinic as part of a thesis study one year ago (January-April 2024) and to examine how many of them continue to meet the criteria for Post-Traumatic Stress Disorder (PTSD), how many receive a diagnosis of Complex Post-Traumatic Stress Disorder (CPTSD), and which factors are associated with these outcomes. In this way, it is aimed to contribute to the literature on the long-term effects of trauma exposure. Additionally, since there is no scale in our country that assesses the diagnosis of CPTSD in children, the study also aims to translate the Child and Adolescent Trauma Screen Scale - 2 (CATS-2) into Turkish and examine its psychometric properties.

Prevalence of Complex PTSD in Trauma-Exposed Children-Adolescents and Related Factors

The aim of this study is to assess the psychiatric evaluation of children and adolescents exposed to trauma in the outpatient clinic and to determine the prevalence of PTSD and Complex PTSD (CPTSD) diagnoses. Additionally, it aims to compare the clinical characteristics of children exposed to trauma who do not receive a PTSD diagnosis, those diagnosed with PTSD, and those diagnosed with CPTSD, as well as to examine the trauma history of their parents and the severity of their anxiety and depression. Furthermore, since there is no existing scale to assess CPTSD in children in our country, the study also aims to translate the International Trauma Questionnaire - Child and Adolescent Version into Turkish and evaluate its psychometric properties.

Study of Emotional Dysregulation in Complex Post-Traumatic Stress Disorder

This study aims to characterize emotional dysregulation in complex post-traumatic stress disorder (cPTSD) and to determine the extent to which it can promote the distinction with borderline personality disorder (BPD) and post-traumatic stress disorder (PTSD). As emotional dysregulation is a dynamic process whose phenomenological manifestations are labile, associated with physiological modifications and modulated by cognitive processing, a multiple methodology associating measurements in a real-life ecological context with measurements performed in the hospital will be preferred. Overall, this study proposes to capture, for the first time, the clinical manifestations associated with cPTSD from the perspective of emotional dysregulation and its underlying processes

The Impact of Playing Tetris on Migrants' Mental Health

This study examines if playing Tetris prevents the development of Post-traumatic stress disorder or related anxiety and depressive symptoms. The investigators recruit 300 participants in total in Greece and in the Netherlands. The participants are immigrants who have applied for asylum at any point in the past. The participants are asked to answer three questionnaires (on Post-traumatic stress disorder, related anxiety and depressive symptoms, and post-migration living difficulties) on a recurring basis - once every 4 weeks, 12 times in total. Half of the participants (treatment group) are randomly selected to play Tetris after completing the questionnaires. Participants in the treatment group are instructed to play Tetris for at least 15 minutes while trying to remember bad things that recently happened to them. Tetris is administered at three instances and participants in the treatment group are encouraged to play Tetris in case of experiencing any traumatic events or having any intrusive memories during the course of the study.
