The purpose of this study was to identify health and emotional-related issues of service members after a deployment to Iraq. Secondary data analysis and a cross-sectional descriptive design, were used to analyze data from the Department of Defense Post Deployment Health Assessment (PDHA) database. The cognitive appraisal model of stress and coping (Lazarus and Folkman, 1984) guided this study. Several statistical techniques were used including: frequency distributions cross tab evaluations, factor analysis, reliability calculations, regression analysis and tests for mediation. The study sample included 510, 352 service members (49,998 females, 460,349 males) with a mean age of 29 years. The sample represented all components and branches of the military. Of the total sample, 51.9% (n=264,777) saw wounded, killed or dead individuals and 22.1% (n=112,620) discharged their weapon in combat. Environmental exposures were an important source of stress. Exposures to sand and dust were the largest complaint (89.8% of the sample). Multiple physical symptoms were identified and 40% of the sample reported four or more symptoms (e.g. diarrhea, back pain, headache, fatigue). PTSD symptoms were identified in 11.8% (n = 60,200) and depressive symptoms in 26.5%, (n=123,808) of participants. Results of the study indicated that age, gender, rank, race/ethnicity, military component and branch were important predictors of emotional and health-related concerns in this sample. Appraisal variables (danger of being killed and exposure concerns) mediated the relationship between immediate (physical and depressive symptoms) and long term outcomes (health perception, PTSD symptoms) for the majority of the analyses; supporting the study hypothesis. However, length of deployment did not have a significant impact on stress-related outcomes in this study. Implications for practice, policy and future research are discussed.

INTRODUÇÃO: Apesar dos Inibidores Seletivos da Recaptura da Serotonina (ISRSs) serem a primeira escolha no tratamento do Transtorno de Estresse Pós-Traumático (TEPT) seu mecanismo de ação não é completamente compreendido. Possivelmente, um aumento na resiliência ao estresse esteja envolvido. Como a serotonina (5HT) ajuda a mediar as respostas ao estresse em outros transtornos ansiosos, o paradigma de Depleção de Triptofano Aguda (DTa) foi usado para diminuir a 5HT central em Pacientes com TEPT remitido com ISRSs. MÉTODOS: Dez pacientes com TEPT (diagnosticados pela Mini Entrevista Neuropsiquiátrica Internacional) que tiveram resposta completa com um ISRS (Escala de Impressões Clínicas Globais de Melhora 1-2 por pelo menos 3 meses) foram selecionados para o experimento. Os pacientes foram testados em duas ocasiões diferentes separadas por uma semana nas quais os pacientes receberam uma mistura contendo grandes aminoácidos neutros ou com (Depleção de Triptofano Falsa [DTf]; dia controle) ou sem triptofano (dia DTa). Auto relatos de ansiedade e humor, bem como medidas cardiovasculares, foram obtidos ao longo dos testes. Cinco horas e meia após a ingestão da mistura os pacientes foram re-expostos aos seus traumas através do procedimento de imaginação guiada de Pitman. RESLTADOS: Esses procedimentos provocaram elevados escores nas medidas avaliadas em ambos os dias, com respostas significativamente mais intensas no dia DTa conforme avaliado pelas Escalas Visuais Analógicas (DTa 47,57 [21,75] -v- DTf 20,71 [18,4]; p=0,001), Escala de Trauma de Davidson (29,4 [12,7] -v- 15,7 [7,79]; p=0,001), Inventário de Ansiedade de Spielberger versão Estado (28,9 [11,03] -v- 18,5 [10,13]; p=0,066, e Perfis de Estados de Humor (p<0,001). CONCLUSÕES: Esses dados são os primeiros a demonstrar que a depleção de 5HT piora as respostas subjetivas a re-experimentação de memórias traumáticas no TEPT e sugere que o aumento na função da 5HT induzida por ISRSs diminui os sintomas de TEPT, especialmente sob provocação, i.e. 5HT ajuda a mediar a resiliência ao estresse. Além de fornecer insights sobre o como os ISRSs funcionam no TEPT, esses dados também oferecem uma abordagem de potenciais novos tratamentos para esse transtorno / INTRODUCTION: Although Selective Serotonin Reuptake Inhibitors (SSRIs) are the first-line Posttraumatic Stress Disorder (PTSD) treatments their mechanism of action is unclear, but possibly improvement of stress resilience is involved. As serotonin (5HT) helps regulate stress responses in other anxiety disorders, the acute tryptophan depletion (aTD) technique was used to lower brain 5HT in SSRSs-remitted PTSD patients. METHODS: Ten patients with PTSD (Mini-International Neuropsychiatric Interview diagnosed) who had made a full recovery on SSRIs (Clinical Global Impressions Improvement Scale 1-2 for at least 3 months) were enrolled in the experiment. Patients were tested on 2 separate occasions a week apart - each session they received a drink containing large neutral amino acids either with (Sham Depletion [SD]; control day) or no tryptophan (aTD day). Self reports of anxiety and mood, as well as cardiovascular measures, were obtained throughout the tests. At 5.5 hours after the drink subjects were reexposed to their trauma using a modification of Pitmans imagery guided method. RESULTS: These procedures provoked elevated ratings on both days, with significantly more marked responses on the aTD day according to Visual Analogue Scales (aTD 47.57 [21.75] -v- SD 20.71 [18.4]; p=0.006), Davidson Trauma Scale (29.4 [12.7] -v- 15.7 [7.79]; p=0.001), Spielberger State Anxiety Inventory (28.9 [11.03] -v- 18.5 [10.13]; p=0.066, and Profile of Mood States (p<0.001). CONCLUSIONS: These data are the first to show that 5HT depletion worsens the subjective responses to reliving traumatic memories in PTSD and suggest that that SSRI-induced increases in 5HT function restrains PTSD symptoms, especially under provocation, i.e. 5HT helps mediate resilience to stress. As well as giving insights into how SSRIs work in PTSD, these data may also offer a translational approach to potential new treatments for this disorder

Doctor of Philosophy / School of Family Studies and Human Services / Charlotte Shoup Olsen / Farrell J. Webb / Homelessness has become an enduring fixture of contemporary United States society. Female veterans face a host of unique challenges; females often carry the burden of serving in the armed forces, while balancing marriages, motherhood, and care giving responsibilities in their home lives. As the veterans return to their lives as civilians, the females who served in the military must deal with the possibility of sexual harassment, sexual assault, and rape while in the armed services. Female service members are twice as likely to have Post Traumatic Stress Disorder (PSTD) than their male service members and are three to four times more likely to become homeless. Understanding this view of homelessness from the female veteran’s perspective is limited due to small sample sizes in previous research efforts. However, with the increasing numbers of homeless female veterans it is imperative to understand the risk factors. A qualitative descriptive study was conducted using a modified framework for studying vulnerable populations. The study was designed to explore the meaning of homelessness from the female homeless veteran’s perspective. Second, risk factors were examined for homelessness and the services necessary for the female veteran to exit the homeless cycle. Third, the data were coded and analyzed to identify patterns and commonalities of multiple psycho social factors such as unstable family support, domestic violence, job loss, affordable housing options, substance abuse, mental and physical health issues. These factors were cited as the leading risk factors contributing to the homeless state of this sample of female veterans. The data collection consisted of ten homeless female veterans participating in a private, audio taped interview using a semi-structure interview tool. Resources listed as a necessity to end homelessness consisted of affordable housing, job security, earning a living wage income, transportation, remaining drug free, and being awarded disability. The pathway to homelessness varied for each participant, but they all demonstrated a tremendous amount of resiliency.

L’objectif de cette recherche est d’étudier l’influence spécifique et combinée du contexte de violence conjugale sur le développement socio-affectif des enfants âgés de 5 ans et demi à 12 ans, et d’examiner leurs représentations de la violence et de leurs relations familiales. Notre étude s’appuie sur le modèle de la sécurité émotionnelle de Cummings et Davies (1994). Dans cette perspective, notre échantillon se compose de 32 mères et de 46 enfants âgés de 5 ans et demi à 12 ans, vivant en contexte de violence conjugale. Les mères ont renseigné trois questionnaires qui évaluent l’intensité de la violence conjugale à l’aide du « Conflict Tactic Scale II » (Cyr, Fortin & Chénier, 1997), l’adaptation socio-affective de leur enfant par le questionnaire « Children Behavior Checklist » (Achenbach, 1991), ainsi qu’un questionnaire de renseignements généraux. Les enfants ont, quant à eux, renseigné quatre questionnaires qui permettent de saisir leurs perceptions de la violence avec le « Children’s Perception of Interparental Conflict » (Cyr & Fortin, 2001), le processus de parentification grâce au « Parentification Questionnaire Youth » (Fortin, 2005), les conflits de loyauté à l’aide du « questionnaire des conflits de loyauté » (Fortin, 2005) et les symptômes de stress post-traumatique avec le « Trauma Symptom Checklist for Children » (Briere, 1989). Enfin, le « Systemic Analysis of Group Affiliation » (Compagnone, 2009) a été utilisé avec les enfants afin de saisir leurs représentions de la cohésion et du pouvoir au sein de la famille. Les principaux résultats mettent en évidence que la moitié des enfants présentent des problèmes extériorisés et 82,6% des problèmes intériorisés. Le degré de l’exposition à la violence de l’enfant influence ses représentations de la cohésion familiale, son sentiment de menace et de blâme, ses conflits de loyauté et la présence de certains symptômes de stress post-traumatique. Les représentations de l’enfant sur la violence et les relations familiales, telles que la parentification, le sentiment de blâme, les conflits de loyauté et les représentations de la cohésion et du pouvoir dans la famille, sont prédictives de la présence de symptômes de stress post-traumatique et de troubles de l’adaptation socio-affective. L’effet modulateur de la représentation du pouvoir et de la cohésion familiale, ainsi que les représentations de la violence et les conflits de loyauté ont été mis en évidence. Enfin, plus de la moitié des enfants de l’échantillon, en plus d’être exposés à la violence conjugale, ont aussi été directement maltraités, et les conséquences relevées sont d’autant plus majorées. L’ensemble des résultats obtenus nous permet de proposer des perspectives de recherche et des pistes d’intervention. / The aim of this research is to study the influence of specific and combined context of domestic violence on socio-emotional development of children aged between 5 and a half to 12 and to consider their representations of violence and their family relationships. Our study is based on the model of emotional security Cummings and Davies (1994). With this in mind, our sample consists of 32 mothers and 46 children aged 5 and a half to 12, living in a context of domestic violence. The mothers have filled in three questionnaires assessing first, the intensity of domestic violence using the « Conflict Tactic Scale II » (Cyr, Fortin & Chénier, 1997), the socio-emotional adaptation of their children with the questionnaire « Children Behavior Checklist » (Achenbach, 1991) and then, a general information questionnaire. As for the children, they have filled in four questionnaires that allow to understand their perceptions of violence with « Children's Perception of Interparental Conflict » (Cyr & Fortin, 2001), the process of parentification through the « Parentification Questionnaire Youth » (Fortin 2001), loyalty conflicts with the « loyalty conflicts questionnaire » (Fortin, 2005) and post-traumatic stress symptoms with « Trauma Symptom Checklist for Children » (Briere, 1989). Finally, the « Systemic Analysis of Group Affiliation » (Compagnone, 2009) has been used with the children to understand their representations of cohesion and power within their families.The main results show that half of the children have externalizing problems and 82.6% internalizing problems. The degree of exposure to child abuse influences his representations of family cohesion, his feeling of threat and blames, his loyalty conflicts and the presence of certain symptoms of PTSD. The children’s representations of violence and family relationships, such as parentification, the feeling of blame, loyalty conflicts and the representations of cohesion and power in the family, are predictive of symptoms of post-traumatic stress disorders and social-emotional adjustment. The modulating effect of the representation of power and family cohesion, as well as depictions of violence and conflicts of loyalty have been highlighted. Finally, more than half of the children in this sample, have been exposed to domestic violence but also to direct abuse, that’s why the consequences underlined are all the more important. All these results allow us to propose research perspectives and methods of interventions.
