REVIEW
Teniel Sonya Ramikie, Kerry James Ressler
Following sexual maturity, females disproportionately have higher rates of posttraumatic stress disorder (PTSD) and experience greater symptom severity and chronicity as compared with males. This observation has led many to examine sex differences in PTSD risk factors. Though relatively few, these studies reveal that the root causes of PTSD sex differences are complex, and partly represent interactions between sex-specific nonbiological and biological risk factors, which differentially shape PTSD vulnerability...

OBJECTIVE: Mental defeat and cognitive flexibility have been studied as explanatory factors for depression and posttraumatic stress disorder. This study examined mental defeat and cognitive flexibility scores in patients with panic disorder (PD) before and after cognitive behavioral therapy (CBT), and compared them to those of a gender- and age-matched healthy control group. RESULTS: Patients with PD (n = 15) received 16 weekly individual CBT sessions, and the control group (n = 35) received no treatment...

Individuals with posttraumatic stress disorder (PTSD) are more prone to suicidal ideation and behavior. While those who have experienced interpersonal trauma exhibit more suicidality than those who have experienced non-interpersonal trauma, it is unclear how the traumatic effects are related to an individual's personality characteristics. This study examined the association between interpersonal trauma and personality factors with suicidality, and elucidated the moderating role of interpersonal trauma in individuals with PTSD...

This study employed secondary analyses of existing ecological momentary assessment (EMA) data to characterize hostile and irritable affect in the day-to-day experience of 52 smokers with, and 65 smokers without, posttraumatic stress disorder (PTSD). EMA monitoring occurred over a mean of 8.2 days, and participants responded to an average of 2.8 random prompts/day. Analyses included Wilcoxon rank sum tests of group differences, and path analyses of cross-lagged multilevel models. Participants with PTSD endorsed a significantly higher proportion of total EMA entries indicating hostile affect and irritable affect than did individuals without PTSD...

Episodic future thinking (EFT) refers to the mental simulation of future events that might be personally-experienced; a crucial mental process in adaptation. Psychiatric disorders are associated with deficits in recalling episodic memory, however, no study has reviewed the empirical literature to assess for similar deficits in EFT. A systematic review comparing psychiatric groups with control groups on the specificity and episodic detail of EFT returned 19 eligible studies. An overall effect of g = -0.84 (95%CI = -1...

- Posttraumatic stress disorder (PTSD) is a psychiatric disorder that may develop after traumatic events.- PTSD is one of the most prevalent psychiatric disorders in the Netherlands, with an estimated lifetime prevalence of 7%.- Recurrent re-experiencing of the traumatic event is the most characteristic PTSD symptom.- Recognition of PTSD may be hampered by the heterogeneous symptomatology, avoidance to talk about the trauma and highly frequent comorbid psychiatric and somatic comorbidity.- Feelings of guilt and shame may also influence reported trauma history...

Previous studies have examined the concurrent relationship between posttraumatic stress disorder (PTSD) and a range of psychophysiological variables, including respiratory sinus arrhythmia (RSA). However, there is a lack of research examining the prospective development of trauma symptomatology, and the directionality of the association between RSA level and PTSD has yet to be determined. The current study is the first prospective study to examine whether RSA level and RSA reactivity are risk factors for PTSD symptoms in children...

REVIEW
Donald I Abrams
The National Academies of Sciences, Engineering and Medicine conducted a rapid turn-around comprehensive review of recent medical literature on The Health Effects of Cannabis and Cannabinoids. The 16-member committee adopted the key features of a systematic review process, conducting an extensive search of relevant databases and considered 10,000 recent abstracts to determine their relevance. Primacy was given to recently published systematic reviews and primary research that studied one of the committee's 11 prioritized health endpoints- therapeutic effects; cancer incidence; cardiometabolic risk; respiratory disease; immune function; injury and death; prenatal, perinatal and postnatal outcomes; psychosocial outcomes; mental health; problem Cannabis use; and Cannabis use and abuse of other substances...

OBJECTIVE: The authors assessed the efficacy of trauma memory reactivation performed under the influence of propranolol, a noradrenergic beta-receptor blocker, as a putative reconsolidation blocker, in reducing symptoms of posttraumatic stress disorder (PTSD). METHOD: This was a 6-week, double-blind, placebo-controlled, randomized clinical trial in 60 adults diagnosed with long-standing PTSD. Propranolol or placebo was administered 90 minutes before a brief memory reactivation session, once a week for 6 consecutive weeks...

OBJECTIVE: Posttraumatic embitterment disorder (PTED) comprises a stress-related response to a negative life event that violates the belief system of the individual. Characteristic symptoms involve repeated intrusive thoughts, emotional arousal when reminded of the event, and decreases in well-being. METHOD: Within the scope of the present study, embitterment was treated as a continuous rather than categorical concept, and we investigated its psychological and brain structural correlates in a sample of healthy older adults...

OBJECTIVE: Posttraumatic mental disorders may occur with different affect qualities. Best known is posttraumatic stress disorder (PTSD), a conditioned anxiety reaction with intrusions. Another event-related mental disorder is posttraumatic embitterment (PTED), characterized by affect of embitterment and thoughts of revenge, occurring after an event deeply hurting basic beliefs. Knowing about associated disability is important for treatment and sociomedical decisions. This is the first study to explore work-disability in patients with PTSD, PTED, and not-event-related common mental disorder (CMD)...

OBJECTIVE: There is a growing literature on the intergenerational transmission of trauma, representing approaches across psychodynamic, family systems, epidemiological, sociological, and biological levels of analysis. Embitterment has been proposed as a response to severe, but normative, stressful events, different from the life-threatening trauma that precedes posttraumatic stress disorder (PTSD). METHOD: This article reviews the potential applicability of the construct of embitterment to trauma and intergenerational effects through (a) a historical review of the intergenerational transmission of trauma literature, (b) a discussion of embitterment versus PTSD, (c) a brief review of theories of mechanisms of transmission, and (d) a discussion of biological findings and their interpretation...

Cognitive deficits in Posttraumatic Stress Disorder (PTSD) and dissociative symptoms suggest there may be an underlying and persistent problem with temporal processing in PTSD, but this question has not been systematically examined. We investigated the ability of a group of PTSD participants in estimating the duration of supra-second visual stimuli relative to healthy controls. The data of 59 participants with PTSD and 62 healthy controls, collected from the BRID database, have been examined. Overall, our results indicate that PTSD patients overestimate the duration of the displayed stimuli...

Readily defined as symptoms consistent with posttraumatic stress disorder (PTSD), but that occur earlier than 30 days after experiencing the traumatic event, posttraumatic stress syndrome (PTSS) is now acknowledged to be a serious health issue. Even so, PTSS often goes unrecognized until an official diagnosis of PTSD is made. Screening tools such as the PTSS-14 have proven reliable in identifying people with PTSS who are at risk of developing PTSD. Through early recognition, providers may be able to intervene, thus alleviating or reducing the effects of a traumatic experience...

This integrative review explores the current state of knowledge on trauma-focused interventions with resilience as the outcome. The review synthesized the results of 17 intervention studies. Findings of the review demonstrate the importance of including resilience as an outcome measure for the effectiveness of trauma-focused interventions. Findings also provide preliminary evidence that effective trauma-focused interventions both reduce posttraumatic stress disorder (PTSD) symptoms and improve resilience. Further research should include a focus on developing interventions based on established theoretical frameworks, and using resilience outcome measurement tools appropriate to the interventions and the characteristics of the target population...

Survivors of sudden, traumatic death are at risk for a variety of bereavement-related mental health problems, including posttraumatic stress disorder, depression, and prolonged grief disorder. Because these conditions often cooccur, traumatic grief interventions are generally designed to be transdiagnostic, integrative treatments that combine techniques designed to treat a wide range of mood and anxiety symptoms. In this special section, expert clinicians and researchers present a series of papers describing new, integrative treatment models for violently bereaved children and adults and also describe ways that integrative treatments can be enhanced using peer support...

Disproportionate reactions to unexpected stimuli in the environment are a cardinal symptom of posttraumatic stress disorder (PTSD). Here, we test whether these heightened responses are associated with disruptions in distinct components of reinforcement learning. Specifically, using functional neuroimaging, a loss-learning task, and a computational model-based approach, we assessed the mechanistic hypothesis that overreactions to stimuli in PTSD arise from anomalous gating of attention during learning (i.e., associability)...

BACKGROUND: The psychological treatment of choice for patients with severe posttraumatic stress disorder (PTSD) is cognitive behavioural exposure therapy or Eye Movement Desensitisation Reprocessing (EMDR). Whilst these are the most effective treatments, approximately 30-45% of the patients show no significant improvements and follow-up data are sparse. Furthermore, a proportion of patients with severe trauma does not benefit or avoid exposure therapy due to the potential to overwhelm them...

BACKGROUND: After sexual assault, many college women develop symptoms of posttraumatic stress disorder (PTSD), and those who engage in substance use coping are at heightened risk for this outcome. Positively-perceived social support has been identified as an important protective factor against the development of PTSD, but received social support could involve problematic behaviors-like the encouragement of coping through use of alcohol and/or drugs-that could worsen symptoms. METHODS: In the current study, 147 undergraduate women with a lifetime history of sexual assault completed two waves of self-report measures assessing their symptoms...

Servicewomen exposed to traumatic stressors over the course of their military service are at increased risk of developing symptoms of substance use disorder (SUD) and posttraumatic stress (PTS). They are also at risk for exposure to military sexual assault (MSA), which is also associated with SUD and PTS symptomology. Research is unclear about the incremental contributions of different forms of traumatic stressors on co-occurring SUD and PTS symptomology. In this study we examined the independent and combined effects of MSA and other military stressors on SUD and PTS symptomology in a sample of female veterans (N=407)...
