Moral injury (MI) is associated with severe blame-related emotion and the development of psychopathology including posttraumatic stress disorder (PTSD). Little is known about how MI events are neurally processed when PTSD is comorbid, limiting the development of tailored interventions. Thus, this thesis sought to provide a novel, multi-method examination of the biological underpinnings of moral injury and relevant behavioural correlates. Study one provides the first investigation into the neural activation patterns elicited during MI event recall in military members and public safety personnel with PTSD, relative to MI-exposed civilian controls. In PTSD, emotional processing is challenged by heightened sensory information. Here, we provide evidence of heightened viscerosensory information processing (i.e. internal gnawing or gastrointestinal constriction related to blame-based emotion) during MI event recall, which appears to exert a strong influence over cortical regions facilitating moral cognitive processes including emotion regulation, autobiographical memory integration, and social cognition. Overwhelming visceral sensations can elicit defensive behaviour including tonic immobility (TI), a defensive response that facilitates viscerosensory dampening. Interestingly, more severe negative alterations in cognition and mood were associated with viscerosensory dampening in our PTSD group, pointing towards a compensatory pattern of emotional numbing. Studies two and three explore two posttraumatic symptoms consistent with emotional numbing: alexithymia and posttraumatic TI. In study two, we explore posttraumatic TI as a survival-based dissociative response and test a new measure of posttraumatic TI. In study three, we provide evidence that alexithymia is associated with an altered (muted) pattern of emotion-specific bodily sensation. This thesis provides a framework for embodied MI event processing in PTSD and highlights the importance of assessing the somatic experience of MI and screening for TI responses and emotional numbing as part of PTSD symptomatology. The evidence presented here suggests sensorimotor-based approaches and bottom-up regulatory strategies may be useful adjuncts to MI event processing. / Dissertation / Doctor of Philosophy (PhD) / Moral injury (MI) is a psychosocial-spiritual injury that can occur when deeply held values are violated either by oneself or a trusted other; it produces considerable pain and social alienation. MI has been linked to suicide and the development of posttraumatic stress disorder (PTSD), a mental health condition associated with distressing symptoms and reduced functioning in important areas of life, including social relationships. This thesis focuses on how MI events are processed by military members and public safety personnel, who are both at risk for MI and PTSD. We investigate how shame is experienced in the brain and body, and explore how intensified visceral sensations may become overwhelming (e.g., pit in stomach, vomiting) prompting emotional numbing or difficulties remaining embodied in the present moment (e.g., zoning out, freezing up). By understanding MI event processing when PTSD is present, we hope to gain insight into more effective treatments for these individuals.

In his thesis, Re-authoring life narratives of trauma survivors in KwaZulu-Natal: Spiritual perspective, the researcher investigates a holistic understanding of the effects of trauma on surviving individuals and communities historically affected by political violence in KwaZulu-Natal, South Africa. Traditionally, the exploration of the impact of trauma on survivors in South Africa has been focused mainly on the bio-psycho-social aspects. The Bio-psycho-social approach recognises that trauma affects people on several dimensions- biological, social and psychological. However, Nevid (et al 2006:19) and Kaminer (et al 2012) acknowledge that these bio-psychosocial factors are incomplete for us to understand the effects of trauma on the individual and call for consideration of all possible pathways and account for multiple factors, influences, and interactions. Using qualitative and narrative approach, personal life narratives were listened to with the aim of looking in depth at the effects of traumatic experiences on the research participants, and specifically investigate whether, and how trauma affected their spirituality. The findings show that the research participants sustained psychological, moral and spiritual injuries during and after traumatic experiences. The results concur with Buckenham’s (1999:7-8) argument that trauma wreaks its toll in the life of a person emotionally, psychologically, spiritually, in our relationships with ourselves, others and with God. The study also established that regardless of religious affiliation, research participants turned to spiritual resources for answers, healing and recovery in traumatic situations. Therefore, the study recommends the integration of the spiritual perspective to reach a holistic model of understanding and treating traumatized individuals and communities. Although the study is localised in the South African context, the results have a much wider relevance in understanding the role of ‘posttraumatic spirituality’ in the re-authoring of life narratives shattered by trauma. / Thesis (PhD)--University of Pretoria, 2013. / gm2014 / Practical Theology / unrestricted

The current study takes an initial step toward deriving a method for empirically based, theory-driven treatment matching in a military population suffering from PTSD. Along with the more overt symptoms of PTSD (e.g., persistent hyperarousal), secondary cognitive symptoms have also been shown to be significantly associated with avoidance and intrusive symptoms, as well as contribute to functional impairment. Based on the factor analytic and treatment literature for PTSD, it appears that there are two central mechanisms associated with beneficial therapeutic change that underlies both CPT and PE treatments (i.e., habituation, changes in cognitions). Additionally, different traumatic events and peritraumatic responses may be associated with unique symptom profiles and may necessitate targeted treatment. The present study proposes a novel approach to treatment matching based on the factor structure of PTSD and underlying mechanisms of treatment response. More broadly, this paper provides evidence for a broader understanding of peritraumatic responses and the potential implications of these responses for symptom profiles and illness trajectories.

This paper provides an analysis of Bradshaw and Colleagues' model of military healthcare professionals' moral distress experiences. Using novel interview data collected from Canadian Forces healthcare professionals, the steps of the model are validated or potential refinements are suggested. / Military healthcare professionals (HCPs) may experience moral distress during international deployment. Moral distress is experienced when a HCP faces a moral dilemma, e.g., knows the morally correct course of action but is blocked from taking it, or where all available courses of action require something of moral significance be given up. While the literature indicates that moral distress often negatively impacts the mental health of the individual and the effectiveness of the organization, limited research has examined moral distress amongst military HCP. Many similar stressors and psychological health problems are present for both civilian and military HCP; however, the unique context of deployment necessitates further examination. This thesis explores the military HCP experience with moral distress by using Bradshaw and colleague’s model of progression from the encounter with a moral dilemma to the impact on individuals and organizations. Through the analysis of novel interviews collected by the Ethics in Military Medicine Research Group (EMMRG), Bradshaw and colleague’s model of military moral distress is compared to participant’s experiences and qualitatively analysed, with the results outlining where the model is supported and where refinement is recommended. These challenges were then supported by a literature review from the disciplines of virtue and feminist ethics, moral psychology, bioethics, and civilian HCP moral distress research. Two novel and significant revisions to the model are suggested: representing and integrating the cumulative experience of moral distress, and re-conceptualizing the resolution process based on the consideration of contextual controllability on moral responsibility. / Thesis / Master of Science (MS) / This thesis examines the experience of moral distress in military healthcare professionals (HCPs) while working abroad, where a HCP faces a moral dilemma, e.g., knows the morally correct course of action but is blocked from taking it or it requires something of moral significance be given up. This thesis analyses the most recent model of military HCP moral distress (Bradshaw, et al., 2010) by comparing it to the experiences described by participants in the Ethics in Military Medicine Research Group (EMMRG) study. The results outline support for the model as well as novel suggestions for revision, which are supported by literature from a variety of disciplines. Two adjustments to Bradshaw and colleague’s model are suggested: clearer representation of the cumulative nature of moral distress as well as a reconceptualization of the resolution process to consider the influence of the immediate and extended environment on moral responsibility.
