Posttraumatische Störungen bei Patienten mit Erkrankungen aus dem schizophrenen Formenkreis

Background The findings of international studies suggest high rates of interpersonal violence and posttraumatic stress disorder (PTSD) among patients with schizophrenia spectrum disorders. Only few studies, however, have so far been conducted in the German-speaking countries. Objectives The aim of our study was to determine the prevalence of lifetime experiences of interpersonal violence and comorbid PTSD among inpatients in a German university hospital. Method In N = 145 consecutively admitted patients with schizophrenia spectrum disorders (67 % male) the structured trauma interview (STI) was used to assess experiences of interpersonal violence and the structured clinical interview for DSM-IV (SCID) to assess comorbid PTSD. Results Sexual violence under the age of 16 years was reported by 17 % of the patients (women 27 %, men 12 %). Approximately one third (32 %) reported physical violence by parental figures (women 38 %, men 29 %). At least one form of early violence (sexual or physical) was reported by half of the women (48 %) and one third of the men (34 %). Negative sexual experiences later in life were reported by 17 %, physical violence by 38 % and at least one of these forms by 48 % of the patients. In total two thirds of all patients (66 %) reported experiences of violence during their lifetime. The prevalence of acute PTSD was 12 %. Another 9 % of patients had a subsyndromal PTSD. Conclusion The present study confirmed the high rates of experiences of interpersonal violence and comorbid PTSD in a German sample of patients with schizophrenia spectrum disorders. Violence and it’s consequences should therefore be routinely assessed and the full spectrum of trauma-specific therapies should be integrated into the treatment of this group of patients.

Second Wave Positive Psychology: Exploring the Positive–Negative Dialectics of Wellbeing

Positive psychology has tended to be defined in terms of a concern with ‘positive’ psychological qualities and states. However, critics of the field have highlighted various problems inherent in classifying phenomena as either ‘positive’ or ‘negative.’ For instance, ostensibly positive qualities (e.g., optimism) can sometimes be detrimental to wellbeing, whereas apparently negative processes (like anxiety) may at times be conducive to it. As such, over recent years, a more nuanced ‘second wave’ of positive psychology has been germinating, which explores the philosophical and conceptual complexities of the very idea of the ‘positive.’ The current paper introduces this emergent second wave by examining the ways in which the field is developing a more subtle understanding of the ‘dialectical’ nature of flourishing (i.e., involving a complex and dynamic interplay of positive and negative experiences). The paper does so by problematizing the notions of positive and negative through seven case studies, including five salient dichotomies (such as optimism versus pessimism) and two complex processes (posttraumatic growth and love). These case studies serve to highlight the type of critical, dialectical thinking that characterises this second wave, thereby outlining the contours of the evolving field.

The Fenix II Study: A longitudinal study of psychopathology among burn patients

Psychological symptoms are common among burn survivors. However, knowledge about epidemiology and predictors of psychopathology has shown great heterogeneity in this population. The Fenix-II Project was the first epidemiological study on the psychopathological consequences of burn injuries developed in Spain, providing a detailed analysis of the progression of psychological symptoms during the first six months after injury. Three hundred and thirty-three patients were monitored and 183 were included in this study. Posttraumatic, depression and anxiety symptoms showed a general decreasing tendency across time. At 6 months, 34 patients showed clinically significant Posttraumatic Stress Disorder (PTSD) symptoms (20.5% of 166 patients reached at 6 months) as measured with the MINI Neuropsychiatric Interview. Within this group of patients, anxiety, depression and hyperarousal increased at 30 days, and avoidance 90 days after injury. The most accurate predictors of PTSD were found to be being burned in a Motor Vehicle Accident, risk of social exclusion, low body-image adjustment, anterior trunk location of the burn injury and life threat perception during the burn-shock period. Considering these factors, clinicians may identify patients at risk of PTSD development, allowing an adequate follow up and preventive interventions which may minimize the psychological consequences of burn injuries.

A DYNAMIC FRAMEWORK FOR THE RELATIONS BETWEEN FOREIGN EXCHANGE RATES, SAVINGS AND INVESTMENTS

The Meese-Rogoff forecasting puzzle states that foreign exchange (FX) rates are unpredictable. Since one country’s macroeconomic conditions could affect the price of its national currency, we study the dynamic relations between the FX rates and some macroeconomic accounts. Our research tests whether the predictability of the FX rates could be improved through the advanced econometrics. Improving the predictability of the FX rates has important implications for various groups including investors, business entities and the government. The present thesis examines the dynamic relations between the FX rates, savings and investments for a sample of 25 countries from the Organization for Economic Cooperation and Development. We apply quarterly data of FX rates, macroeconomic indices and accounts including the savings and the investments over three decades. Through preliminary Augmented Dickey-Fuller unit root tests and Johansen cointegration tests, we found that the savings rate and the investment rate are cointegrated with the vector (1,-1). This result is consistent with many previous studies on the savings-investment relations and therefore confirms the validity of the Feldstein-Horioka puzzle. Because of the special cointegrating relation between the savings rate and investment rate, we introduce the savings-investment rate differential (SID). Investigating each country through a vector autoregression (VAR) model, we observe extremely insignificant coefficient estimates of the historical SIDs upon the present FX rates. We also report similar findings through the panel VAR approach. We thus conclude that the historical SIDs are useless in forecasting the FX rate. Nonetheless, the coefficients of the past FX rates upon the current SIDs for both the country-specific and the panel VAR models are statistically significant. Therefore, we conclude that the historical FX rates can conversely predict the SID to some degree. Specifically, depreciation in the domestic currency would cause the increase in the SID.

International Transmission of the Business Cycle in a Multi-Sector Model.

Multi-country models have not been very successful in replicating important features of the international transmission of business cycles. Standard models predict cross-country correlations of output and consumption which are respectively too low and too high. In this paper, we build a multi-country model of the business cycle with multiple sectors in order to analyze the role of sectoral shocks in the international transmission of the business cycle. We find that a model with multiple sectors generates a higher cross-country correlation of output than standard one-sector models, and a lower cross-country correlation of consumption. In addition, it predicts cross-country correlations of employment and investment that are closer to the data than the standard model. We also analyze the relative effects of multiple sectors, trade in intermediate goods, imperfect substitution between domestic and foreign goods, home preference, capital adjustment costs, and capital depreciation on the international transmission of the business cycle.

L'influence des traumas psychologiques sur l'intervention en toxicomanie

Il est possible qu’une personne qui consulte pour un problème d’utilisation de substances souffre également d’un problème associé à un état de stress post-traumatique ( ESPT ). Plusieurs auteurs croient qu’il existe un lien expliquant cette co-morbidité. Voilà pourquoi plusieurs hypothèses ont été formulées pour expliquer le lien entre un trouble tel que celui lié à l’utilisation de substance (TUS) pouvant exister avant l’ESPT, la vulnérabilité suite au TUS, ainsi que l’automédication. Plusieurs recherches proposent deux types d’interventions afin d’aider les personnes aux prises avec cette double problématique. La première consiste à traiter les deux problèmes séparément alors que la seconde, préconise une approche intégrée et simultanée. Puisque les écrits conseillent davantage un traitement intégré, il y aura une présentation d’une de ces formes de traitement nommé « À la recherche de la sécurité ». Le volet académique visait à comprendre le lien existant entre le TUS, les traumas psychologiques et l’ESPT ainsi que les différentes formes d’interventions pour aider les personnes ayant cette co-morbidité. Nous avons utilisé un module du programme « À la recherche de la sécurité » récemment traduit en français afin de vérifier sa mise en application et l’appréciation qu’en ont fait cinq usagers du Centre Dollar-Cormier-Institut universitaire sur les dépendances (CDC-IUD) ayant vécu un traumatisme au cours de leur vie. En conclusion, il sera démontré dans nos résultats que les hypothèses quant au lien de comorbidité sont effectivement présentes dans la réalité des personnes ayant un ESPT et un TUS, et qu’une intervention intégrée offre des points positifs autant pour l’usager que pour l’intervenant.

État de stress post-traumatique comorbide, facteurs de risque et de protection parmi des individus itinérants en traitement pour des troubles liés à l’utilisation de substances

Peu d’études explorent les fréquences de traumas et d’état de stress posttraumatique (ÉSPT) chez les itinérants, spécifiquement parmi ceux avec des troubles liés à l’utilisation de substances (TUS). L’objectif principal de cette étude était de mesurer les fréquences de trauma et d’ÉSPT parmi les usagers en traitement pour des TUS à Montréal. L’autre objectif était de vérifier les différences entre ceux ayant ou non un ÉSPT. 51 individus itinérants, 9 femmes et 42 hommes, ont constitué l’échantillon. L’âge moyen était de 46 ans (SD = 7.19). Les participants ont vécu en moyenne 4.24 (SD = 2.06) types de trauma. 49% de l’échantillon avaient potentiellement un diagnostic d’ÉSPT. La majorité avait: un parent alcoolique, vécu un trauma dans l’enfance et un soutien social faible. Les participants qui avaient potentiellement un diagnostic d’ÉSPT: avaient un parent alcoolique, vécurent un trauma dans l’enfance et utilisaient davantage de stratégies de coping inadaptées.

La consommation d’alcool et de drogue chez les étudiants suite à la fusillade de Dawson en 2006 : une analyse différenciée selon le sexe

Objectifs : Étudier l’incidence de la dépendance à l’alcool ou aux drogues chez les étudiants exposés à la fusillade du Collège Dawson dans les 18 mois suivant celle-ci. Identifier les précurseurs au développement d’une dépendance à une substance psychoactive en tenant compte de la sévérité d’exposition à l’événement. Examiner si la consommation d’alcool 18 mois après les événements est en lien avec les différents groupes de symptômes d’état de stress post-traumatique. Méthode : La population à l’étude est composée de l’ensemble des étudiants du Collège Dawson au moment de l’événement. Les analyses ont été faites auprès de 854 étudiants inscrits au Collège au moment de la fusillade. Résultats : Cinq pourcent des femmes et 7 % des hommes présentent pour la première fois de leur vie un problème de dépendance à une substance suite à la fusillade. Pour les hommes, leur jeune âge, la présence de pensées suicidaires au cours de leur vie, ainsi que le fait d’avoir vu le tireur au moment de la fusillade sont les principaux précurseurs de cas incidents de dépendance. Aucun des précurseurs étudiés n’est significatif pour les femmes. Les hommes et les femmes se distinguent également quant aux symptômes d’état de stress post-traumatique qui prédisent la consommation d’alcool 18 mois après la fusillade. Conclusion : La principale retombée de l’étude est de souligner l’importance de considérer le sexe des individus pour étudier leur consommation de substances psychoactives suite à un traumatisme.
