Background: Traumatic events can cause social tension, anxiety, panic and other psychological crises, and can even cause post-traumatic stress disorder (PTSD) and suicide. Physical activity has a good role in promoting mental health, and has a great application prospect in individual psychological intervention after traumatic events. However, no systematic review of the relationship between physical activity and individual mental health after traumatic events affecting many people has been published so far, which makes it impossible for people to understand the research status in this field from a holistic perspective. Objective: This review explores the relationship between physical activity and individual psychology, physiology, subjective quality of life and well-being after traumatic events, so as to provide some valuable clues or enlightenment for individual psychological intervention after traumatic events. Method: Relevant literature was searched in five databases, summarised, sorted and studied. Results: Thirty-three study papers were included in this review, the main study findings include: (1) Physical activity is positively correlated with individual mental resilience and subjective well-being after traumatic events, and negatively correlated with anxiety, depression, tension and PTSD. (2) Individuals with higher levels of physical activity have better mental health status after traumatic events than those who do not regularly engage in physical activity. (3) Physical activity can promote sleep quality, self-efficacy, subjective quality of life and various physiological functions of those experiencing traumatic events. (4) Physical activity (including exercise) is regarded as one of the preferred nursing measures to buffer against mental stress and maintain physical and mental health for those experiencing traumatic events. Conclusion: The level of physical activity is positively correlated with individual physical and mental health before and after traumatic events. Physical activity can be used as one of the effective measures to improve individual mental health after traumatic events. Physical activity can be used as one of the important measures to improve mental health of those experiencing traumatic events. Regular physical activity can reduce the impact of traumatic events on mental health, both before and after the events.

The European Journal of Psychotraumatology has had a long interest in advancing the science around climate change and traumatic stress. In this special issue, we include papers that responded to a special call in this area. Six major themes emerge from these papers and together they contribute to trauma and adversity model of the mental health impacts of climate change. We argue that, in addition to individual vulnerability factors, we must consider the (i) cumulative trauma burden that is associated with exposure to ongoing climate change-related impacts; (ii) impact of both direct and indirect stressors; (iii) individual and community protective factors. These factors can then guide intervention models of recovery and ongoing resilience.

Background and objective: The aims of this study were to estimate the lifetime and 12-month prevalence of exposure to potentially traumatic events (PTEs) in young men in Switzerland and to assess factors and mental health outcomes associated with such events. Method: Data were drawn from the Cohort Study on Substance Use Risk Factors (C-SURF), encompassing 5,223 young men. Exposure to PTEs was assessed using the Post-traumatic Diagnostic Scale (PDS), Trauma History Questionnaire (THQ) and Life Event Checklist (LEC). Results: Lifetime prevalence of PTEs was 59.4%, with 37.3% reporting multiple types of events. Twelve-month prevalence was 31.2%, with 12.7% reporting multiple types of events. Low education level of participants, high maternal education, family affluence below average, and not living with biological parents were associated with a higher risk of having experienced one or more PTEs in one's lifetime. Low education level of participants and high maternal education were also related to exposure to one or more PTEs over the past 12 months. Logistic regression analyses demonstrated that PTE exposure was directly associated with all assessed mental health outcomes. The strongest relationship was found between exposure to multiple types of PTEs and suicide attempts (adjusted OR 4.9 [95% CI: 2.9-8.4]). Conclusions: These results indicate that having experienced one or multiple types of PTEs is common in Swiss young men. Efforts should be intensified to reduce exposure to PTEs and prevent and treat resulting problematic mental health outcomes in young adults. * Exposure to PTEs is common among young Swiss men.* Education level of participants and of their mothers, family affluence and living arrangements are associated with PTE exposure.* PTE exposure is associated with AUD, MD and suicide attempts.* Efforts should be intensified to reduce exposure to PTEs and to prevent and treat resulting problematic mental health outcomes in young adults.

Background: Traumatic Events (TEs) are often seen as risk factors not only for the development of eating disorders (EDs) but also for their impact on the severity of clinical presentation and psychiatric comorbidities. Objective: This study aimed to assess the prevalence and time of occurrence of TEs in the two subtypes of anorexia nervosa (AN; restricting [RAN] and binge-purging [BPAN]) and to investigate differences in TEs (number, type, frequency) as well as clusters of post-traumatic symptoms and emotional dysregulation between the two groups. Method: Seventy-seven hospitalized women were recruited and divided into two subgroups according to their AN subtype. Participants completed the following self-reported measures: Eating Disorder Inventory-2 (EDI-2), Life Events Checklist (LEC), Impact of Events Scale-Revised (IES-R) and the Difficulties in Emotion Regulation Scale (DERS). Results: A higher occurrence of TEs was found in patients with BPAN than in those with RAN. In particular, there were significantly more women in the BPAN group than in the RAN group who had been sexually assaulted. Exposure to TEs happened before the onset of illness in most patients, regardless of the AN subtype. Finally, the BPAN group had significantly higher scores in terms of post-traumatic symptoms and emotional dysregulation than RAN patients. Conclusions: Patients with BPAN showed a higher occurrence of TEs, post-traumatic symptom clusters, and emotional dysregulation than those with RAN. These findings are of interest as treatments could benefit from trauma-informed interventions for those affected by AN, and particularly for those with the binge-purging subtype. * Traumatic events are common among patients with both subtypes of anorexia nervosa.* Higher number and occurrence of TEs were found in patients with binge-purging anorexia nervosa than those with the restricter subtype.* Patients with binge-purging anorexia nervosa reported higher post-traumatic symptoms and emotion dysregulation than those with the restricter subtype.

Background: Best practice guidelines recommend traumatic events should be assessed in psychosis to support the identification and, when indicated, treatment of post-traumatic stress reactions. However, routine assessment in frontline services is rare, and available tools are not tailored to psychosis. Assessment obstacles include lengthy measures, a focus on single, physically threatening events, and the exclusion of psychosis-related traumas. Objective: To develop and validate a brief trauma screening tool for the identification of clinically significant traumas in people with psychosis. Method: The Trauma and Life Events (TALE) checklist was developed in conjunction with people with lived experience of trauma and psychosis, and specialist clinicians and researchers. The psychometric properties (i.e. test-retest reliability, content validity, construct validity) of the TALE were evaluated in a sample of 39 people with psychosis diagnoses. Results: The TALE displayed moderate psychometric acceptability overall, with excellent reliability and convergent validity for sexual abuse. High rates of psychosis-related trauma and childhood adversity were reported, in particular bullying and emotional neglect. A dose-response relationship between cumulative trauma, post-traumatic stress and psychosis was found. Conclusions: The TALE is the first screening tool specifically designed to meet the needs of routine trauma screening in psychosis services. The psychometric limitations highlight the challenge of developing a measure that is both sufficiently brief to be useful in clinical settings and comprehensive enough to identify all relevant adverse events. Validation of the TALE is now required across the spectrum of psychosis.

Background: There is an ongoing debate about the validity of the A1 criterion of PTSD. Whereas the DSM-5 has opted for a more stringent A1 criterion, the ICD-11 will leave it out as a key criterion. Objective: Here we investigated whether formal DSM-IV-TR traumatic (A1) and stressful (non-A1) events differ with regard to PTSD symptom profiles, and whether there is a gender difference in this respect. Method: This was examined in a large, mostly clinical sample from the Netherlands Study of Depression and Anxiety (n = 1433). Participants described their most bothersome (index) event and were assigned to either an A1 or non-A1 event group according to this index event. Results: Remarkably, in men PTSD symptoms were even more severe after non-A1 than A1 events, whereas in women symptoms were equally severe after non-A1 and A1 events. Moreover, while women showed significantly higher PTSD symptoms after A1 events than men (29.9 versus 15.4% met PTSD criteria), there was no gender difference after non-A1 events (women: 28.2%; men: 31.3%). Furthermore, anxiety and perceived impact were higher in women than men, which was associated with PTSD symptom severity. Conclusion: In sum, while women showed similar levels of PTSD symptoms after both event types, men reported even higher levels of PTSD symptoms after non-A1 than A1 events. These findings shed a new light on the role of gender in PTSD symptomatology and the clinical usefulness of the A1 criterion.

Barriers reported in previous studies were not confirmed in our sample of therapists with a high rate of specific trauma training. Group differences were found for therapist's gender, own traumatic events, length of work experience, and theoretical orientation. Traumatic events are strongly associated with mental health problems. At present, traumatic events and trauma-specific needs are commonly underdetected in therapeutic settings. Many mental health professionals lack key competencies for trauma inquiry and treatment. In this study, we aimed to investigate the everyday practices of dealing with traumatic events in outpatient psychotherapy in Germany as well as the influence of the therapist's gender, own traumatic events, length of professional experience, and theoretical orientation. A total of 148 outpatient psychotherapists completed a purpose-designed online questionnaire. Therapists rated barriers and attitudes towards trauma assessment, possible requirements for enquiring about trauma, and practical aspects of trauma assessment. Barriers reported in previous studies, e.g. fear of offending the patient or exacerbating their psychological state, could not be confirmed in our sample. Overall, participating therapists felt confident in engaging with traumatic events and considered enquiring about trauma important in all patients. Group differences were found for therapist's gender, own traumatic events, length of work experience, and theoretical orientation. Our results suggest that trauma training lowers barriers and raises therapists' self-confidence in dealing with patients´ traumatic experiences. Therapists' characteristics effecting trauma assessment should be considered during training. Due to the increasing demand for psychotherapy, especially considering people with severe mental illness affected by traumatic events, trauma training should be obligatory for all mental health professionals.

HIV/AIDS and potentially traumatic events (PTEs) or stressful life events (SLEs) and/or PTSD are independently associated with neurocognitive impairment (NCI). Literature suggests that HIV and PTE/SLE exposure independently and consistently affect various domains of cognition including language ability, working memory and psychomotor speed. There are limited data on the interaction between HIV infection and PTEs and their combined effect on NCI. In this systematic review, we synthesise evidence for the combined effect of HIV infection and PTEs and SLEs and/or post-traumatic stress disorder (PTSD) on NCI of people living with HIV/AIDS (PLWHA) from high-, middle- and low- income countries. Our inclusion criteria were observational epidemiological studies (case-control, cohort and cross-sectional designs) that investigated the interaction of HIV infection, PTEs and SLEs and/or PTSD and specifically their combined effect on NCI in adults. We searched a number of electronic databases including Pubmed/Medline, PsycINFO, Scopus and Global Health using the search terms: cognition, HIV/AIDS, observational studies, trauma and permutations thereof. Fifteen studies were included in the review, of which the majority were conducted in high-income countries. Ten of the fifteen studies were conducted in the United States of America (USA) and five in South Africa. Seven of these focused on early life stress/childhood trauma. The remaining studies assessed adult-onset PTEs and SLEs only. Eight studies included women only. Overall, the studies suggest that PTE and SLE exposure and/or PTSD are a significant risk factor for NCI in adults living with HIV, with impairments in memory and executive functions being the most likely consequence of PTE and SLE exposure. These findings highlight the need for trauma screening and for the integration of trauma-focused interventions in HIV care to improve outcomes.

Background: Experiencing a potentially traumatic event can put individuals at risk for both short-term and long-term mental health problems. While many psychological interventions exist for those who have experienced potentially traumatic events, there remains controversy about the best ways to support them. Objective: This review explores the effect of brief psychoeducational interventions after potentially traumatic experiences on adult recipients' mental health, attitudes towards mental health, and trauma-related knowledge, as well as the perceived acceptability of psychoeducation. Methods: Four electronic databases were searched for relevant published literature. Results: Ten papers were included in the review. There was no evidence that psychoeducation was any more effective in terms of reducing mental health symptoms than other interventions or no intervention at all. There was some evidence that psychoeducation improved attitudes towards and knowledge of mental health immediately post-intervention; one study examined whether these improvements were sustained over the long term and found that they were not. However, psychoeducation was generally highly regarded by participants. Conclusions: This review did not find sufficient evidence to support routine use of brief psychoeducation as a stand-alone intervention. Brief single-session psychoeducation interventions delivered within a month of experiencing a potentially traumatic event do not appear to have a significant impact on mental health.

Background: The presence of mild traumatic brain injury (mTBI) increases post-traumatic stress disorder (PTSD) symptoms in the months following injury. However, factors that link mTBI and PTSD development are still unclear. Acute stress responses after trauma have been associated with PTSD development. mTBI may impair cognitive functions and increase anxiety immediately after trauma. Objective: This research aimed to test the possibility that mTBI increases acute stress symptoms rapidly, which in turn results in PTSD development in the subsequent months. Method: Fifty-nine patients were recruited from the emergency rooms of local hospitals. Post-mTBI, acute stress, and PTSD symptom severity were measured using the Rivermead Post-Concussion Symptoms Questionnaire (RPQ), Acute Stress Disorder Scale (ASDS), and PTSD Checklist for DSM-5 (PCL-5), respectively. Results: Moderated mediation analysis indicated that ASDS, at 2 weeks post-trauma, mediated the relationship between RPQ scores at 2 weeks and PCL-5 scores at 3 months post-trauma, only for patients who met mTBI diagnostic criteria. Conclusions: These findings present preliminary evidence suggesting that acute stress disorder symptoms may be one of the mechanisms involved in the development of PTSD among trauma survivors who have experienced mTBI, which provides a theoretical basis for early intervention of PTSD prevention after mTBI.
