First responders who participate in disaster are at risk of posttraumatic stress disorder (PTSD). Because of nurses’ unique role as professional and volunteer responders, there is a need to know more about risks of PTSD in this group. Using a cross-sectional correlational design, associations between disaster exposure, problem focused coping (PFC), emotion-focused coping (EFC) and PTSD symptoms (Impact of Events Scale-Revised (IES-R) scale) were explored. A random sample (n= 995) was drawn from a list of nurses from the New Orleans region. Each nurse was mailed an invitation to participate in an online survey. Three post-card reminders were sent. The sample was divided into nurses who participated in disaster activities (n=76) and those who did not (n=32). Prevalence of PTSD in the PIDA nurses was 13.2%. Almost half the PIDA nurses (48.7%) reported symptoms of PTSD, and increased use of substances to cope (31.5%). Only 9.2% sought psychological care post-event. Regression analyses, controlling for history of trauma, marital status, and gender found EFC accounted for a significant amount of the variance of symptoms of PTSD (R2 = 0.32, F (1, 67) = 25.09, p < 0.001) (B=0.4, SE=0.01, p Prevalence of PTSD among PIDA nurses was lower than other groups of professional responders (17.4% in firefighters), but greater than the general public (6.8%). Presence of PTSD in PIDA nurses five years after Hurricane Katrina is associated with the increased use of EFC and substances.

This study examined the association between traumatic exposure and mental health outcomes in sheltered homeless children. Also investigated was the moderating role of perceived social support in the pathway between traumatic exposure and emotional distress. Trauma exposure was conceptualized in two ways: first through lifetime exposures to abuse, neglect, negative peers, community and interpersonal violence, and the loss of significant attachment figures, and; second through highly stressful events that occur s pecifically in the context of homelessness. Mental health outcomes included symptoms of depression, anxiety, anger, aggression and posttraumatic stress. Perceived social support was measured through inventories of relationships with mothers, fathers, siblings and best friends. The sample consisted of 81 children between the ages of 8-16 and one of their parents. Hierarchical multiple regression analyses found that lifetime trauma exposure and homeless specific complex stress independently accounted for a significant amount of the variance in symptoms of depression, anxiety, aggression, and posttraumatic stress. Lifetime trauma alone accounted for the variance in anger and anxiety related symptomatology. Perceived social support was found to have no influence on mental health morbidity. The study consisted of a novel approach to understanding the psychological experiences of sheltered homeless children. These findings inform the design of clinical interventions for this vulnerable population of children and may have important public policy implications.

Child trauma exposure (CTE) is an important public health concern in the U.S.; more than two-thirds of children report experiencing a traumatic event by the age of 16. CTE may have important acute and long-term physiological, developmental, behavioral, and psychological implications if not addressed. Trauma-focused cognitive behavioral therapy (TF-CBT) is the gold standard for treatment of child trauma and is well-supported for resulting in significant decreases in negative mental health outcomes associated with CTE. Despite the efficacy of evidence-based interventions such as TF-CBT, many children do not receive treatment due to a variety of contextual, logistical, and interpersonal barriers. This mixed-methods exploratory study examines possible predictors of enrollment and completion of TF-CBT, specifically parental trauma exposure, at a community organization that serves abused and traumatized children in the metro Atlanta area. Data were collected during individual assessments consisting of a computer survey and semi-structured interview (n=41). Data analysis focused on parental trauma exposure, and qualitative interviews were examined for common themes regarding intentions for their child’s enrollment and completion of services. Results indicated that caregivers of children referred to services had relatively high (56.1%) rates of trauma exposure. Results from logistical regression indicate that parents with a trauma history were 10.5 times more likely to have a child enroll in therapy. These results indicate that parents with personal trauma histories may be more committed to their child receiving services, therefore public health efforts aimed towards educating parents without trauma histories may be beneficial.

Magister Artium - MA (Psychology) / Post-apartheid South Africa has been marked by high levels of trauma resulting from exposure to violence. Many South Africans are therefore at risk for developing Posttraumatic Stress Disorder (PTSD). Despite a large body of research identifying various protective factors which may influence an individual's response to a traumatic event, a gap in South African research on the relationship between exposure to multiple traumatic experiences, protective factors and the development of PTSD was identified. Therefore, located within the systems theory framework, the aim of this study was to investigate the relationship between demographic characteristics, types of exposure to trauma and resilience associated with the development of posttraumatic stress (PTS) when there are multiple exposures to trauma. A quantitative, cross-sectional, exploratory study on 158 psychology students at the University of the Western Cape was undertaken. Using a non-random, convenience sampling method, data were collected by means of four self-report questionnaires namely; a biographical questionnaire, the Life Events Checklist for DSM-5 (LEC-5), the Resilience Scale for Adults (RSA), and the Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5).

Doctor of Philosophy / School of Family Studies and Human Services / Briana S. Goff / Human sex trafficking is a complex and unique phenomenon involving the commercial sexual exploitation (CSE) of persons by means of force, fraud, or coercion. The purpose of this study was to investigate unique patterns of trauma exposure and biopsychosocial health among a sample of CSE survivors. Results from a latent profile analysis with 135 adults trafficked in the United States yielded three distinct survivor sub-groups: mildly distressed, moderately distressed, and severely distressed. The mildly distressed class (18.5%) was characterized by the lowest reports of trauma exposure and an absence of clinically significant psycho-social stress symptoms. The moderately distressed class (48.89%) endorsed comparatively medial levels of trauma exposure, as well as clinically significant disturbance in six domains of psycho-social health. The severely distressed class (32.59%) reported the highest degree of trauma exposure and exhibited clinically significant symptoms of pervasive psycho-social stress across all domains assessed. To better understand variation in CSE survivors’ engagement with formal support services, this study also examined differences in help-seeking attitudes and intentions between latent classes. Results indicated that compared to those in the mildly and moderately distressed classes, severely distressed survivors endorsed significantly more unfavorable attitudes toward seeking professional help, along with no intention to seek help from any source when facing a personal or emotional crisis. Findings from this study provide a snapshot of significant heterogeneity in trauma exposure and biopsychosocial health among CSE survivors, as well as associated differences in help-seeking attitudes and intentions. The identification of distinct survivor sub-groups in these and future analyses mark an important intermediate step toward developing empirically-testable support services that are specifically designed to meet the unique needs of CSE survivors.

Le traumatisme psychique définit le choc émotionnel d'un individu à la suite à d'un évènement traumatique. Dans certains cas, la symptomatologie psychotraumatique s'installe et perdure entrainant l'apparition d'un Trouble de Stress Post Traumatique. La littérature décrit amplement les désordres mnésiques qui accompagnent la maladie et notamment l'altération de la mémoire autobiographique. Ce système de mémoire complexe renferme l'histoire de notre passé sur laquelle s'appuie notre individualité présente et nos aspirations futures. Cependant, l'origine du dysfonctionnement de la mémoire autobiographique reste confuse, cette altération pourrait être un facteur prémorbide, la conséquence de l'exposition traumatique ou celle de la maladie. Les recherches restent incertaines sur les relations existantes entre le dysfonctionnement de la mémoire autobiographique et le traumatisme psychique. Tout au long de ce travail, nous caractériserons le fonctionnement de la mémoire autobiographique dans le contexte d'un traumatisme psychique. Les deux premières études permettront d'analyser la mémoire autobiographique suite à une exposition traumatique unique et suite à des expositions répétées. La dernière étude nous éclairera sur le fonctionnement de la mémoire autobiographique chez des sujets en rémission partielle d'un trouble de stress post traumatique. / Psychological trauma defines the emotional shock experienced by an individual following a traumatic event. In some cases, the psychotraumatic symptomatology develops and persists, leading to the onset of posttraumatic stress disorder. The literature has widely described the memory impairment associated with the disease, especially dysfunction of autobiographical memory. This complex memory system contains the story of our past, on which our present identity and future aspirations are based. However, it remains unclear whether this deficit is due to premorbid autobiographical memory dysfunction, to the trauma exposure itself, or to the subsequent development of posttraumatic stress disorder symptomatology. Research has not yet clarified the relationship between autobiographical memory dysfunction and psychological trauma. Throughout this work, we will define autobiographical memory function in the context of psychological trauma. The first two studies will analyze autobiographical memory function following a single traumatic exposure and following repeated exposures. The final study will shed light on how autobiographical memory functions among participants with posttraumatic stress disorder in partial remission.

Exposure to traumatic situations is routine for child welfare workers in California, and the attrition rate for newly hired social workers in some states is estimated to be nearly 50% in the 1st year of employment. Prior research has indicated that reasons for dissatisfaction included dysfunctional organizational climate and culture. The purpose of this study was to examine the extent to which trauma exposure contributed to secondary traumatic stress and intent to quit and to examine the degree to which organizational climate moderated the exposure among direct service child welfare employees. Kurt Lewin's field theory, Figley's theory of secondary traumatic stress or compassion fatigue, and McCann and Pearlman's constructivist self-development theory were foundational for this study. The research questions determined whether a) trauma exposure to would relate positively with secondary traumatic stress and intent to quit, b) organizational climate would relate negatively with secondary traumatic stress and intent to quit, and c) organizational climate would moderate the relationship between trauma exposure and secondary traumatic stress as well as intent to quit. Pearson correlations indicated that exposure to traumatic situations was statistically related to secondary traumatic stress but not intent to quit, and organizational climate was statistically significant in relation to secondary traumatic stress and intent to quit. Hierarchical regression analysis indicated no interaction effect on either dependent variable but might have approached significance with a larger sample. Positive social change can occur through child welfare organizations emphasizing strategies that can reduce secondary traumatic stress and turnover.

These original data for this research were documented in the clinical diary records of an army psychiatrist on deployment in Vietnam during 1969–70. This study is unique due to the original battlefield diagnosis data used for foundation comparison analysis and longitudinal retrospective case control paired measurement. In battlefield psychiatric assessment diagnostic data recorded in Vietnam during 1969–70 of 119 Australian military servicemen (Experimental group) who presented battlefield trauma exposure reactions were examined. The research case controls (Control group) are 275 Australian Vietnam veterans selected from data at the Australian War Memorial Research Centre. Case control identified participants did not present with medical symptoms in 1969-70 and presented the same demographic profile as the Experimental group population. This research examined whether initial psychiatric illnesses initiated by battlefield trauma exposure in 1969-70 by a cohort of Vietnam veterans would have long term pernicious effects on their physical and psychological health, relationships and employment status. This research compared, PTSD, delayed onset PTSD, severity of combat exposure and depressive symptoms, quality of dyads, general health and quality of life. The analysis of specific demographic variables determined the means, standard deviations, and medians for those continuous variables for both groups from 1969-70 (n=394) and 2006-07 (n=97). The 2006-07 Experimental group (n=21) represents 17.65% and the Control group (n=76) represents 28.15% of the original groups selected and matched from 1969-70 data. These participants completed a battery of psychometric questionnaires and a follow up telephone interview. Demographic variables were evaluated for inclusion as covariates. These demographic variables were correlated with combat exposure and the presentation of PTSD in 1969-70 and 2006-07. PTSD identified in 2006-07 was modelled as a latent variable with three manifest indicators (re-experiencing, hyper-arousal and avoidance). Categorical variables were determined by frequency tables for respective group participants. Group differences in continuous variables were analysed by t-test or the Wilcoxon signed rank sum test accounting for non-normal distributions. Categorical variables, chi-square tests or Fisher's Exact Tests were performed when assumptions of chi-square tests were violated. Research participants from 1969-70 and 2006-07 did not indicate a significant difference in demographic, categorical or continuous variables. Initial 1969-70 battlefield psychiatric diagnosis TSD did indicate of a causal link to delayed onset PTSD in research participants in 2006-07. The PTSD (2006-07 diagnosis) indicated a descriptive difference, 64 of the 76 Control met the diagnostic criteria, while 19 of the 21 Experimental met the criteria. A significant difference was identified in the 2006-07 presence and severity of depression, two symptoms (intrusion and avoidance) of PTSD and the reported combat exposure. The prevalence of delayed onset PTSD was also highlighted. Obtaining original battlefield psychiatric diagnoses is rare. Comparison with an identifiable Control group after 35 years informs knowledge of how military personnel cope with battlefield exposure. Specifically concluding that; battlefield exposures during 1969-70 for the majority of the research participants have impacted detrimentally on their psychological and physical health, relationships, employment and ongoing overall wellbeing to this day. Delayed onset PTSD is the principal indicator of this current state for these veterans. / Thesis (Ph.D.) - University of Adelaide, School of Population Health and Clinical Practice, 2008
