This report examines the state of research regarding the psychological impact of war on American soldiers deployed in military operations in Afghanistan (Operation Enduring Freedom) and Iraq (Operation Iraqi Freedom). Particular focus is given to examination of marital and relationship satisfaction within the Hispanic soldier and veteran population. A wide range of research examines the traumatic aftereffects of wartime service with predominant themes of posttraumatic stress, depression, anxiety, and substance abuse appearing across the literature. Examination of the Hispanic population is disputed with researchers producing conflicting findings: some researchers have indicated an increased risk of psychological disturbances in Hispanic wartime veterans while other have found no such difference between the Hispanic and majority groups. Attempts to explain these discrepant results have ranged from differences in acculturation, to potentially increased traumatic exposure, or to underlying feelings of persecution and alienation. However, consistent results were found in regards to the negative relationship between traumatic exposure and romantic relationship satisfaction. Younger males of lower socioeconomic status with increased trauma exposure and comorbid mental health diagnoses consistently reported less relationship satisfaction than their peers. Given the nature of family and the importance of close relationships within the Hispanic culture, it is increasingly necessary for clinicians working with Hispanic veterans to be aware of these findings. This author purposes that future researchers explore this concept of relationship satisfaction within the Hispanic veteran population with attention given to potentially mediating variables such as level of acculturation and traumatic experience exposure. / text

The purpose of this study is to provide an inclusive portrait of the experience of female spouses living with traumatized male Canadian soldiers healing from Post-Traumatic Stress Disorder (PTSD). By facilitating the articulation of the spouses' stories this research gives a voice to and fosters appreciation for this neglected population. As well, this study helps clarify the needs and possible therapeutic interventions for spouses of soldiers in psychotherapy for PTSD. Although recently there has been an increased focus on addressing PTSD in soldiers, there has been comparatively little research and clinical attention given to the soldiers' families. For this study, in-depth interviews were conducted with six spouses of former peacekeeping Canadian soldiers who received group therapy for PTSD. Using the Life Story interview method, a spontaneous picture of the spouses' experiences was elicited as part of a comprehensive relationship narrative. This provided the opportunity for understanding the experience of living with a soldier in treatment for PTSD within a couple relationship and larger social context. Narrative summaries were created from the interviews and follow-up was conducted with each participant to gain feedback on these narratives. Participants were also given the opportunity to read each other's narratives and discuss their impressions. The narrative summaries are presented along with thematic results. The participants' stories revealed instances of aggression, primary trauma and problems related to their husbands' periods of alcohol abuse, so Figley's model of Secondary Traumatic Stress was not the best conceptual fit to explain the experiences of these women. Limited support was found, however, for Hobfoll's (1998)model of a loss spiral to help describe the descent into chronic disability associated with combat-related PTSD as well as the difficulties soldiers experience in their transition from military service. This study's implications for practice include recommendations for groups for military spouses; the need to address the iatrogenic suffering of soldiers and their spouses; treatment recommendations for soldiers with PTSD. Future research also needs to include delivery and evaluation of a group-based counselling intervention for the spouses of traumatized soldiers.

Fatal earthquakes such as that which occurred in Christchurch on February 22nd 2011, can result in survivors having difficulties with cognitively processing the event, which may be the precursor to posttraumatic stress symptoms. Trauma related dissociation has been proposed to be a mechanism related to these cognitive processing difficulties. Most research focusing on information processing and dissociation post-trauma has conducted controlled analogue studies or has not focused solely on information processing and dissociation. There is also scant research on these constructs across therapy. In response to this gap in research, two studies were developed. An association was proposed between dissociation and information processing as demonstrated by an increase in conceptual processing and a reduction in dissociation. It was predicted that an improvement in these constructs would be related to a reduction in PTSD symptoms over therapy. Study1 applied a case-study design to 5 individuals who were attending therapy for post-traumatic stress disorder in response to the trauma they had experienced from the Christchurch earthquakes. Study 2 assessed information processing and dissociation (via self and observer report) in 20 individuals who had direct exposure to the effects of the earthquake. Earthquake information processing and dissociation were assessed as they were happening nearly two year’s post-quake using correlation analyses and hierarchical regressions. The hypotheses were partially confirmed, in that an increase in conceptual processing was not shown to be associated with a reduction in dissociation. However, an increase in conceptual processing was shown to be related to trauma symptom improvement particularly for re-experiencing symptoms. In addition, study 2 demonstrated a possible relationship between trait dissociation and arousal symptoms. These findings partially support the proposed role information processing and dissociation play in the recovery from PTSD. The findings suggest that trauma related difficulties should be assessed as early as possible to resolve issues related to a delay in symptom reporting.

Despite the established relationship between Post-Traumatic Stress Disorder (PTSD) and depression in Western cultures, research concerning the prevalence rates and relationship between the comorbid disorders in Non-Western communities remains sparse. The present study explored the relationship between PTSD and comorbid depression in citizens currently living in Ghana, West Africa. Ghanaian Nationals (n=140) completed the PTSD and demographic sections of the Structured Clinical Interview for the DSM-IV (SCID-I), as well as the Center for Epidemiological Studies Depression Scale (CES-D). Both measures were administered through interview format. Results revealed a lower prevalence rate of PTSD than expected. Further analysis demonstrated that meeting the diagnostic criteria for PTSD increased the chance of meeting the diagnostic criteria for depression, as well as increased depression scores. To confirm that the prevalence rates found in this study were reflective of actual cases of depression (not measurement error) a scale reliability analysis was conducted on the CES-D. The results of this analysis confirmed internal consistency. Results suggest that although the prevalence rate of PTSD was low, a relationship is present between the disorders in a non-Western sample. The reliability of the measures means that PTSD and depression were assessed for, but what is not certain is whether the actual construct of the disorders could occur differently in a non-Western sample, causing a different presentation of symptoms. Future research is needed to examine the Western construct of PTSD and depression to determine if there is a different presentation of symptoms not accounted for by Western measures. / Department of Psychological Science

The aim of this thesis was to investigate psychological factors influencing the development and maintenance of post-traumatic symptoms, with particular attention to the role of dissociation. The concept of dissociation is at present not well understood, and a secondary aim of this thesis was to clarify its meaning and structure and enable its assessment. Chapter 2 reports the development and testing of a questionnaire measuring trait dissociation, and the factor analysis of this questionnaire into seven sub-factors with low to medium intercorrelations, along with an analysis of the reliability and validity of this questionnaire, which was used in the subsequent studies. Chapters 3 and 4 consist of experimental studies investigating the relationship between dissociation and later intrusive memories using a videotape of scenes from road traffic accidents as a stimulus. The first study attempted to manipulate dissociation, while the second used extreme scorers on the trait dissociation questionnaire. The manipulation of dissociation proved difficult, but both studies showed a relationship between dissociation and later intrusions. Chapters 6 and 7 report on two prospective clinical studies following road traffic accident victims over the first six months following their accident, and investigates the role of dissociation and other psychological factors in the development of post-traumatic symptoms. Both state and trait dissociation, and the emotional numbing subfactor of dissociation in particular, predict the later development and maintenance of other post-traumatic symptoms. Persistent dissociation was more predictive of later symptoms than dissociation in the first few days after the accident. These results are discussed in relation to current thinking about the concept of dissociation and the DSM diagnoses of post-traumatic stress disorder and acute stress disorder. In particular it seems useful to distinguish between components of dissociation in terms of their relationship to PTSD. Possible future research and clinical implications are also addressed.

Current theories of PTSD propose that impaired retrieval of trauma memories may impede processing of these memories and subsequent trauma recovery. This thesis investigated memory retrieval processes in trauma survivors with and without symptoms of posttraumatic stress, and in non-traumatised individuals exposed to a highly arousing event. Study 1 examined deliberate avoidance of unwanted memories in recent trauma survivors. The results indicated that attempts to forget were associated with poorer recall of forgotten information, but the size of this effect did not depend on the presence or absence of Acute Stress Disorder (ASD). Study 2 investigated automatic retrieval inhibition in trauma survivors with or without Posttraumatic Stress Disorder (PTSD). The results suggested that repeated retrieval of trauma-related information by individuals with PTSD can cause inhibition of related, but unpractised information. Studies 3 and 4 examined the relationship between the vantage point of trauma memories, avoidance and posttraumatic stress symptomatology. The findings indicated that recalling a traumatic event from an observer perspective is associated with post trauma avoidance. They also showed that an observer vantage point in the initial few weeks after trauma is associated with poorer long-term post trauma adjustment. Studies 5, 6 and 7 were analogue studies which analysed the impact of heightened arousal on memory retrieval in novice skydivers. The results suggested that elevated arousal can interfere with retrieval of information related to the arousal-inducing event. Study 7 also indicated that autobiographical memory for the event may be impaired. Finally, Study 8 examined the qualities of trauma memories that were accessed via different modes of retrieval. The results provided evidence that intrusive memories were experienced as more realistic and with more intense affect than memories for the same event that were deliberately retrieved. Together, the findings of this program of research extend current theories of PTSD by highlighting the mechanisms through which retrieval of trauma memories may be impaired. The results suggest that the quality of trauma memories is affected by avoidance processes, elevated arousal and level of conscious control the individual exerts over retrieval.
