Le trouble de stress post traumatique, une pathologie de la réactivation mnésique ? Recherche d'un découplage monoaminergique et de nouvelles tentatives thérapeutiques chez le rat / Post-traumatic stress disorder, a pathology of memory reactivation? In search for monoaminergic uncoupling and new therapeutic approaches on ratsLe Dorze, Claire 12 December 2016 (has links)
Le Trouble de Stress Post-Traumatique (TSPT) est une pathologie qui se développe chez des sujets exposés à des événements traumatiques. Cette pathologie est caractérisée par des reviviscences du traumatisme induisant des troubles anxieux invalidants et durables. Ces reviviscences, provoquées par des indices de rappel, sont à l'origine des fréquentes rechutes qui caractérisent le TSPT. La dépendance aux drogues d'abus est également caractérisée par une hyperréactivité aux indices de rappel qui est responsable du désir irrépressible de drogue ou " craving " et des nombreuses rechutes après abstinence. Nous avons fait l'hypothèse que cette susceptibilité aux indices environnementaux, commune aux deux pathologies, pourrait être due à un découplage des systèmes monoaminergiques induit par l'exposition à des conditions intenses, drogues d'abus ou traumatisme. Les données de cette thèse montrent que notre modèle animal de traumatisme (le Single Prolonged Stress) reproduit chez les individus vulnérables les symptômes de la pathologie, et une réactivité aux indices de rappel. Nos données indiquent également qu'un traumatisme induit, chez les individus vulnérables, une désensibilisation comportementale et une sensibilisation noradrénergique corticale, supportant l'hypothèse de découplage monoaminergique. Enfin, nous avons développé une nouvelle approche thérapeutique, le " remodelage émotionnel " capable de diminuer durablement les symptômes de type TSPT. Les résultats obtenus dans cette thèse, soutiennent l'hypothèse de bases physiologiques communes entre le TSPT et l'addiction, et proposent de nouvelles approches thérapeutiques pour ces deux pathologies. / Post-Traumatic Stress disorder (PSTD) appears on a part of individuals exposed to traumatic events. This pathology is characterized by frequent re-experiencing of the traumatic event inducing disabling and long-lasting anxiety disorders. These flashbacks, triggered by reminder cues, are responsible for the frequent relapses that characterize PTSD. Addiction to drugs of abuse is also characterized by a hyper reactivity to reminder cues which is responsible for drug craving and relapses. We hypothesized that such a susceptibility to environmental cues, common to both pathologies, could be due to an uncoupling of monoaminergic systems induced by exposure to intense conditions (trauma or drugs). Data from this thesis showed that our animal model of PTSD (the Single Prolonged Stress) reproduced PTSD-like symptoms on vulnerable rats, and reactivity to reminder cues. Our data also showed that trauma induced a behavioral desensitization and a cortical noradrenergic sensitization, in vulnerable traumatized rats, supporting the hypothesis of monoaminergic uncoupling. Finally, we developed a new therapeutic approach, the "emotional remodeling" which was shown to durably decrease PTSD-like symptoms. The results obtained in this thesis support the hypothesis of common physiological basis between PTSD and drug addiction, and offer new therapeutic approaches for these two pathologies.

Violation and healing of the spirit : psycho-social responses to war of Mozambican women refugeesSideris, Catherine Tina 28 August 2012 (has links)
D.Litt et Phil. / For over a decade, from the late 1970's to October 1992, a war raged in Mozambique that resulted in what has been described as, one of the "most terrible genocides in the history of Africa". Over 4 million people were displaced during this war. Conservative estimates put the number of Mozambicans who sought refuge in South Africa at 250 000. This study examines the trauma created by the war, and its psycho-social outcomes, from the perspective of women refugees who came to settle in villages in the Nkomazi region of Mpumalanga province, in South Africa. Posttraumatic stress disorder, the concept which dominates research in the field of trauma studies, was based on research with male war veterans in western industrial societies. Recently a body of work has emerged which questions the validity of applying posttraumatic stress disorder to contexts of massive social conflict, and its utility in cross cultural contexts. This body of work suggests that an understanding of extreme trauma and its outcomes requires careful consideration of the social and cultural dimensions of trauma. The inclusion of a cultural formulation in the latest edition of the Diagnostic and Statistical Manual for Mental Disorder, DSM-IV, reinforces a growing acknowledgement amongst mental health researchers of the influence of culture on mental health and disorder. The gaps in research on African women survivors of war and the lack of standardised assessment tools, makes this an exploratory study which uses qualitative research methods. Unstructured interviews were conducted with 30 Mozambican women refugees to explore their experiences and definitions of trauma, the psycho-social outcomes of the trauma, and coping and survival in the aftermath of the war. The magnitude of the trauma evident in the research findings called for a conceptual definition which reflects multiple risks and the interdependence of social and individual trauma. Thematic analysis and qualitative coding of the interview data revealed clinically well defined posttraumatic stress disorder symptoms and locally specific discourses of suffering framed by cultural beliefs, social practices and historical experiences. Their testimony and observations in the field, revealed that the survivors demonstrated a capacity to survive and reconstruct their lives. Their coping strategies and survival tactics were fundamentally shaped by socio-historical experiences and the limits and possibilities contained in the recovery environment. The results of this study suggest an approach to examining the complex relationship between trauma and its consequences, which abstracts neither trauma nor its victims from cultural and social-historical contexts.

Trekangs en diensjare as voorspellers van posttraumatiese stresversteuring onder polisiebeamptesKnoetze, Johanna Aletta 28 August 2012 (has links)
M.A. / The goal of the present study was to investigate the relationship between trait anxiety, years of service and posttraumatic stress disorder in the South African Police Service. This study was regarded as important because posttraumatic stress can have a significant influence on the personal life and work-related performance of police officers. One hundred and twenty white, male police officers volunteered to participate in the study. A structural model of the relationships between trait anxiety, years of service and posttraumatic stress was postulated. The model specified that trait anxiety and years of service influence posttraumatic stress both individually and jointly. Trait anxiety is operationalised by means of the IPAT Anxiety Scale and posttraumatic stress disorder by means of the Posttraumatic Stress Disorder Interview Schedule. The fit of the postulated model with the observed data was investigated by means of structural equation modelling. The results indicated that the postulated model showed an acceptable fit with the observed data. The estimated parameters of the model indicated that the subscales of the IPAT Anxiety Scale and the Posttraumatic Stress Disorder Interview Schedule are good indicators of their respective constructs. It was further shown that trait anxiety and years of service have a significant influence on posttraumatic stress disorder. The results support those of previous studies where it was shown that these variables can influence posttraumatic stress disorder. The present study emphasizes that trait anxiety may predispose police officers to the development of trait anxiety. The study also shows that if police officers are exposed to extended periods of traumatic experiences, they run the risk of developing posttraumatic stress disorder.

Die verband tussen persoonlikheidstrekke en posttraumatiese stresversteuring by polisiebeamptesHenning, Catherina Sophia. 13 August 2012 (has links)
M.A. / The present study was undertaken in an attempt to understand and ascertain the relation between personality traits and posttraumatic stress (PTSD) in the South African Police Service (SAPD) leading to chronic illness and work-related dysfunctions. The specific hypothesis for this study will show that by means of the Comrey Personality Scales (CPS) a statistic significant distinction between police officers with PTSD and police officers without PTSD exists. The testing of the hypothesis entailed a group of 120 functional police officers that consists of white, male nonofficers. They worked in the Pretoria area of the SAPD. The PTSD status of the subjects was assessed by means of the PTDS Interview Guide of Watson, Juba, Manifold, Kucala and Anderson (1991). Police officers that met the criteria for PTSD by means of the PTSD Interview Guide were place in one group (PTSD-group, n = 414. Police officers that did not meet the criteria were placed in another group (Non-PTSD-group, n = 79). Personality traits were measured by means of the CPS. There was a significant difference between the personality traits of the PTSDgroup in comparison with the Non-PTSD-group. The PTSD-group appears to be more compulsive and ordered, more introspective, more neurotic, more sensitive and more defensive in comparison with the Non-PTSD-group. It is postulated that these personality traits can possibly cause policemen to be more susceptible for the development of PTSD.

Slagoffers se konstruksies rondom motorkapingsVorster, René 14 October 2015 (has links)
M.A. (Psychology) / South Africa in 1997 is commonly seen as one of the most violent non-war countries in the world. Crime has become so much part of the daily routine of the average South African, that it is almost accepted as the norm. This study investigates the experiences of six persons, directly affected by a violent crime. The researcher endeavours to relate the constructions the victims hold around their experience of a car-jacking as truthful as possible and thus uses the paradigm of social constructionism ...

A phenomenological exploration of client experiences of trauma debriefing by lay counsellorsChandler, Fiona Mary January 2007 (has links)
Magister Psychologiae - MPsych / South Africa is a country with one of the highest crime rates in the world, resulting in
much violence and trauma. Trauma debriefing models are used with groups and individuals in an attempt to facilitate the trauma recovery process and prevent the development of post-traumatic stress disorder (PTSD). There has been much debate on
the efficacy of trauma debriefing over the past two decades with few qualitative studies
exploring the utility of debriefing. A phenomenological methodology was used in this
study, with the aim of understanding how participants experienced the process of trauma
debriefing and what aspects were perceived as helpful or unhelpful. Semi-structured in-
depth interviews were conducted with six adults who received debriefing following a
single traumatic event, by volunteer lay counsellors from the Community Intervention
Centre (CIC) based at the Milnerton Medi-Clinic.

The relationship between experiences in the South African special forces and current levels of well-being and sense of coherenceMoorcroft, Harold Sean 15 May 2007 (has links)
War inevitably impacts on the lives of soldiers who participate in them. The impact often suggests a negative nature, leaving some soldiers with permanent physical and emotional scars. Some soldiers will return from war suffering from several psychological disorders as the result of their exposure to combat trauma. Pathologies such as post-traumatic stress disorders, anxiety and mood disorders are not uncommon. Yet, for others war has provided them with numerous positive experiences from which they can find meaning for themselves. It was Aaron Antonovsky who developed the idea of salutogenesis, mainly focussing on the psychological factors that allow individuals to find meaning in their adversity. This study attempts to investigate the impact of service rendered in the South African Special Forces during the Angolan war on current levels of well-being and sense of coherence amongst former Special Forces members. It is commonly known that these soldiers were exposed to severe battle related conditions, often working behind enemy lines for unknown periods of time whilst being self-reliant. It would seem that most of these soldiers have adapted adequately to society 15 years after their participation in the Angolan war (South Africa’s “Border War”). Some of these soldiers have achieved success in many different ways after leaving Special Forces. Some have embarked into the world of business and others chose professional careers and then there are those who became successful entrepreneurs. A sample of 32 respondents was collected. All of the respondents were members of the South African Special Forces during the Angolan war but have resigned since. The respondents were requested to complete a questionnaire consisting of a biographical information section, Antonovsky’s 13-item Orientation to Life Questionnaire (OLQ) and Diener’s Satisfaction With Life Scale (SWLS). The purpose was to determine the respondents’ current sense of coherence and level of well-being and to determine to what extent service in Special Forces has contributed to these levels. Descriptive and inferential statistics were used to analyse the data. Inferential statistics included Chi-square, Fisher’s exact test, Spearman correlation coefficient and the t-test. Analysis of data suggests that the sample currently measures high on both levels of sense of coherence and well-being. The means of both OLQ and SWLS of this sample compare higher to any other samples they were administered to. However, statistically no clear correlation could be determined between service rendered in Special Forces and current levels of well-being. Respondents did however indicate that they feel that their service in Special Forces did have a positive impact on their lives and their current levels of functioning. / Dissertation (MA (Clinical Psychology))--University of Pretoria, 2007. / Psychology / unrestricted

The experiences and perceptions of police members regarding the effectiveness of trauma debriefing within the South African Police ServiceChabalala, Tinyiko Godfrey 18 October 2005 (has links)
Certain individuals, such as police officers, are exposed to traumatic events as part of the occupational roles they fulfill. In order to prevent psychological illnesses; namely the Post-Traumatic Stress Disorder (PTSD) that results from work-related traumatic incidents, psychological interventions have been developed such as Critical Incident Stress Debriefing. The aim of the study was to explore the experiences and the perceptions of police members stationed at the South African Police Service (SAPS) Head Office in Pretoria, regarding the effectiveness of Trauma Debriefing within the SAPS environment. The researcher was motivated to choose this subject as a result of the challenges he faced while working as a Psychometrist and a Debriefer within the SAPS. Furthermore, the lack of research and literature studies concerning the effectiveness of trauma debriefing motivated the researcher to conduct the study. The qualitative approach was utilized in this study, and interviews were used to gather data about the experiences and perceptions of police members regarding the effectiveness of trauma debriefing. Utilizing an interview schedule, the researcher interviewed 10 respondents who were functional members of the SAPS. A systematic sampling method was used to select suitable respondents for the study. The type of research used was that of applied research, as the intention was to answer practical questions about the effectiveness of trauma debriefing within the SAPS. The exploratory design was utilized in this study, since there was limited information about the experiences and perceptions of police members in existence. The purpose of using this design was thus to explore the perceptions and experiences of police members regarding the effectiveness of trauma debriefing in order to provide new information about the topic. The researcher believes that this research will provoke some thought about new scientific research into this field of study. A discussion on the theoretical overview on trauma debriefing focused on the goals and theories of debriefing. In addition, a theoretical overview of the debriefing model adopted by the SAPS, the benefits of debriefing, the diagnostic criteria for PTSD and critical perspectives with regard to the effectiveness of trauma debriefing. The research findings indicated that trauma debriefing has been viewed and experienced by most respondents as good. Most police members perceived trauma debriefing as effective. Furthermore, police members perceived trauma debriefing as management=s support. The research findings however also indicated that trauma debriefing should be pro-active rather than reactive. Some respondents felt that debriefing should include an element of monitoring members, in order to check their progress. In addition, the study showed that there is a lack of follow-up services to debriefing cases attended. / Dissertation (MSoc.Sci (Employee Assistance Programme))--University of Pretoria, 2006. / Social Work / unrestricted

A child's journey through traumatic grief: a case studyGoliath, Chantal Debra January 2015 (has links)
The death of a parent is one of the most serious stressors that can occur in a child’s life. The aim of this study was to describe an 11-year-old child’s journey through traumatic grief after the violent death of her mother. The conceptual framework utilised was Trauma-Focused Cognitive Behavioural Therapy (TF-CBT). The case study approach was applied as it provided a suitable research design in which to give an account of the subject in a therapeutic situation. A purposive sampling technique was utilised to select the research subject in the study. The following three principles of data collection were adhered to: a) using multiple sources of information, b) creating a case study database, and c) maintaining a chain of evidence. Irving Alexander’s content-analysis technique in conjunction with Guba’s model of trustworthiness was employed for data analysis. The finding that emerged from the study was the resilience shown by Linda in relation to her adaptive functioning following the trauma of witnessing the violent death of her mother. Conclusions and recommendations were made following the findings based on the information obtained during the therapy sessions.

'n Kwantitatiewe beskrywing van die seksueel-misbruikte kindHeslinga, S. 16 August 2012 (has links)
M.A. / This study comments on the debate surrounding behavioural indicators on the child that has been sexually abused. The basic objective of this study is to determine whether behavioural differences can be identified between the child that has been sexually abused and a child that has not been abused. For this research study the quasi-experimental design and specifically the comparison post-test-alone is utilized. The experimental group was exposed to sexual abuse and the comparison group was not exposed to sexual abuse. The result of this study indicates a statistically significant difference toward behavioural indicators, between the experimental group and the comparison group. Children in the experimental group experienced higher levels of psycho-social problems. Therefore it can be accepted that sexual abuse resorts in behavioural changes. It is therefore recommended that behavioural changes are utilized in practice by social workers to verify sexual abuse.
