Key questions remain unaddressed concerning the nature of interpersonal functioning in trauma survivors, including the ability to understand and interpret other peoples thoughts and feelings. Here, we investigate theory of mind (ToM) performance of women with PTSD related to childhood abuse in comparison to healthy controls.

Cortical thickness in bipolar disorder: a systematic review.

Lindsay Hanford; Anthony Nazarov; Geoffrey B. Hall; Roberto B. Sassi

Bipolar disorder (BD) is a debilitating illness, the psychopathology of which is associated with aberrant structural and functional differences in the brain. Despite the many advances in psychiatric research, our understanding of the complex neurobiological underpinnings of BD remains incomplete. The aim of this review was to critically examine all available published magnetic resonance imaging (MRI) research reporting cortical thickness in BD with respect to a healthy population and/or other psychiatric samples.

The aim of this study was to investigate theory of mind (ToM) in a sample of depressed patients with mild symptom severity using a measure with varied cognitive processing demands. Patients demonstrated impaired performance on second-order, cognitively demanding ToM scenarios. Reduced ToM ability was associated with poor psychosocial functioning.

We investigated autobiographical memory in a group of passengers onboard a transatlantic flight that nearly ditched at sea. The consistency of traumatic exposure across passengers, some of whom developed posttraumatic stress disorder (PTSD), provided a unique opportunity to assess verified memory for life-threatening trauma. Using the Autobiographical Interview, which separates episodic from nonepisodic details, passengers and healthy controls (HCs) recalled three events: the airline disaster (or a highly negative event for HCs), the September 11, 2001, attacks, and a nonemotional event. All passengers showed robust mnemonic enhancement for episodic details of the airline disaster. Although neither richness nor accuracy of traumatic recollection was related to PTSD, production of nonepisodic details for traumatic and nontraumatic events was elevated in PTSD passengers. These findings indicate a robust mnemonic enhancement for trauma that is not specific to PTSD. Rather, PTSD is associated with altered cognitive control operations that affect autobiographical memory in general.

Role of morality in the experience of guilt and shame within the armed forces

Anthony Nazarov; R. Jetly; Heather McNeely; M. Kiang; Ruth A. Lanius; Margaret C. McKinnon

Despite advances in our understanding of mental health issues among military forces, a large proportion of military personnel continue to exhibit deployment‐related psychological issues. Recent work has identified symptoms of guilt and shame related to moral injury as contributing significantly to combat‐related mental health issues. This systematic scoping review explores the association between morality and symptoms of guilt and shame within military forces.

Alterations in empathic responding among women with posttraumatic stress disorder associated with childhood trauma

Melissa Parlar; Paul A. Frewen; Anthony Nazarov; Carolina Oremus; Glenda MacQueen; Ruth A. Lanius; Margaret C. McKinnon

Although studies increasingly point toward problems with social cognition among individuals with posttraumatic stress disorder (PTSD), few studies have assessed empathic responding. The aim of the current study was to investigate empathic responding in women with PTSD related to childhood trauma, and the contribution of parental bonding to empathic abilities in this sample.

Introduction Depression is the leading cause of disability worldwide, affecting approximately 350 million people. Evidence indicates that only 60–70% of persons with major depressive disorder who tolerate antidepressants respond to first-line drug treatment; the remainder become treatment resistant. Electroconvulsive therapy (ECT) is considered an effective therapy in persons with treatment-resistant depression. The use of ECT is controversial due to concerns about temporary cognitive impairment in the acute post-treatment period. We will conduct a meta-analysis to examine the effects of ECT on cognition in persons with depression. Methods This systematic review and meta-analysis has been registered with PROSPERO (registration number: CRD42014009100). We developed our methods following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. We are searching MEDLINE, PsychINFO, EMBASE, CINAHL and Cochrane from the date of database inception to the end of October 2014. We are also searching the reference lists of published reviews and evidence reports for additional citations. Comparative studies (randomised controlled trials, cohort and case–control) published in English will be included in the meta-analysis. Three clinical neuropsychologists will group the cognitive tests in each included article into a set of mutually exclusive cognitive subdomains. The risk of bias of randomised controlled trials will be assessed using the Jadad scale. We will supplement the Jadad scale with additional questions based on the Cochrane risk of bias tool. The risk of bias of cohort and case–control studies will be assessed using the Newcastle-Ottawa Scale. We will employ the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) to assess the strength of evidence. Statistical analysis Separate meta-analyses will be conducted for each ECT treatment modality and cognitive subdomain using Comprehensive Meta-Analysis V.2.0.

Comprehension of affective prosody in women with post‐traumatic stress disorder related to childhood abuse

Anthony Nazarov; Paul A. Frewen; Carolina Oremus; E. G. Schellenberg; Margaret C. McKinnon; Ruth A. Lanius

Although deficits in memory and cognitive processing are evident in post‐traumatic stress disorder (PTSD), difficulties with social cognition and the impact of such difficulties on interpersonal functioning are poorly understood. Here, we examined the ability of women diagnosed with PTSD related to childhood abuse to discriminate affective prosody, a central component of social cognition.

Background Preliminary evidence suggests that relative to healthy controls, patients with posttraumatic stress disorder (PTSD) show deficits on several inter-related social cognitive tasks, including theory of mind, and emotion comprehension. Systematic investigations examining other aspects of social cognition, including moral reasoning, have not been conducted in PTSD stemming from childhood trauma. Objective To conduct a comprehensive assessment of moral reasoning performance in individuals with PTSD stemming from childhood abuse. Method Moral reasoning performance was assessed in 28 women with PTSD related to prolonged childhood trauma and 19 matched healthy controls. Performance was assessed using 12 modified moral dilemmas and was queried in three domains: utilitarian/deontological sacrificial dilemmas (personal and impersonal), social order vs. compassion, and altruism vs. self-interest. Participants were asked whether a proposed action was morally acceptable or unacceptable and whether or not they would perform this action under the circumstances described. Results Women with PTSD were less likely to carry out utilitarian actions in personal, sacrificial moral dilemmas, a choice driven primarily by consequential intrapersonal disapproval. Increased concern regarding intrapersonal disapproval was related to higher symptoms of guilt in the PTSD group. Patients with PTSD demonstrated less altruistic moral reasoning, primarily associated with decreased empathic role-taking for beneficiaries. Conclusions Women with PTSD due to childhood trauma show alterations in moral reasoning marked by decreased utilitarian judgment and decreased altruism. Childhood trauma may continue to impact moral choices made into adulthood. Highlights of the article Moral judgment processing was found to be altered in women with PTSD related to chronic childhood trauma. In comparison to healthy women, women with PTSD were less likely to approve utilitarian actions when required to assume their agency in dilemmas involving the infliction of direct physical harm. Decreased likelihood of utilitarian action approval by the PTSD sample was driven by significantly enhanced endorsement of guilt and shame as consequences of such actions. Endorsement of guilt and shame in moral dilemmas was related to increased severity of current clinical symptoms of guilt.

Greater prevalence of post-traumatic stress disorder and depression in deployed Canadian Armed Forces personnel at risk for moral injury

Anthony Nazarov; Deniz Fikretoglu; Aihua Liu; M. Thompson; Mark A. Zamorski

A link between moral injury (i.e., the psychological distress caused by perceived moral transgressions) and adverse mental health outcomes (AMHO) has been recently proposed. However, the prevalence of exposure to morally injurious events and the associated risk of experiencing AMHO remains understudied.
