Information-processing studies have shown an attentional bias (AB) towards threat cues in individuals with anxiety disorders. Research has consistently shown that AB to threat may play a causal role in the development and maintenance of anxiety disorders. Recent empirical evidence has demonstrated support for Attention Retraining (AR) to modify AB to threat, resulting in reductions of anxiety. Currently, AR approaches have not been systematically tested in individuals with Post-traumatic Stress Disorder (PTSD). The purpose of this study was to assess the feasibility of a computer-based attention retraining (CBAR) treatment for clinical levels of PTSD using a modified dot-probe paradigm. A single-case time-series design was employed with a treatment and post-treatment period, following baseline. Results indicated significant reductions in trauma-related symptoms, attention to threat cues, state anxiety and depression, along with a significant increase in coping self-efficacy. AB change for the group was not significant. A significant relationship between AB change and PTSD symptoms was found. The results were discussed from the standpoint of the viability of AR for trauma. / Master of Science

Violent crime and trauma are very common within the society and students at the technikon are as exposed to these traumatic situations that characterize the broader national context as anybody. The purpose of this study was to explore therapeutic intervention techniques that can be used by the educational psychologist in assisting students suffering from post-traumatic stress. The phenomena of post-traumatic stress and post-traumatic stress disorder were studied with reference to the DSM IV classification and description. Traumatic events and stressors among students were outlined. A case study was conducted with a subject selected at the technikon who was suffering from post-traumatic stress due to earlier physical abuse and violence she experienced at home. The Trauma-100-Questionnaire was used to investigate the extent of the trauma and the results showed that the subject was involved with negative self-talk and employed ego defence mechanisms. An analysis of the subject's problem was done through the relations theory and various techniques from the literature study were implemented in therapy with the subject. / Educational Studies / M.Ed.

Thesis (MA)--Stellenbosch University, 2001 / ENGLISH ABSTRACT: Post-traumatic stress disorder (PTSD) is the most recognised mental disorder stemming from severe psychological trauma. One of the differential diagnoses of post-traumatic stress disorder, amongst others, is obsessive-compulsive disorder (OGD). These two disorders overlap at some point in terms of symptomatology. More specifically, both are characterized by recurrent intrusive thoughts. It has been hypothesized that trauma may also be a significant source of OGD development. OGD and PTSD are disorders that present in adulthood, as well as in childhood and adolescence. It is shown that PTSD and OGD can present comorbidly in adulthood and it is theorized that it may also be the case in childhood and adolescence. Evidence of OGD developing in the context of trauma and theories of how this might have happened are presented. It is shown how complicated it is to distinguish between OGD developing in the wake of trauma and PTSD and the importance of such a distinction. / AFRIKAANSE OPSOMMING: Post-traumatiese Stresversteurig (PTSD) is een van die mees erkende sielkundigeversteurings wat ontwikkel na die blootstelling aan sielkundige trauma. Obsessiewe-kompulsieweversteuring (OGD) is, onder andere, een van die differensiële diagnoses van PTSD. Die twee versteurings oorvleuel ten opsigte van simptomalogie. Meer spesifiek word beide gekenmerk deur herhalende indringende gedagtes. Daar word tans gehipotiseer dat trauma nie net 'n rol in die ontwikkeling van PTSD speel nie maar ook 'n oorsaaklike rol het in die ontwikkeling van OGD. OGD en PTSD is versteurings wat kan voorkom tydens volwassenheid, asook tydens die kinderjare en adolessensie. Daar word bewys gedoen van PTSD en OGD wat saam voorkom gedurende volwassenheid en daar word geteoretiseer dat dit ook die geval mag wees tydens die kinderjare en adolessensie. Bewys word gelewer van OGD wat ontwikkel na blootstelling aan trauma en teorië ten opsigte van die ontwikkeling word aangebied. Die onderskeid tussen OGD wat na trauma blootstelling ontwikkel en PTSD is ingewikkeld, dog is die onderskeid baie belangrik in vele opsigte.

This study aimed to determine if Junior Eysenck Personality Inventory (JEPI) scores would differentiate between youth with and without PTSD. More specifically, the study compared JEPI Neuroticism and Extraversion scores across youth with PTSD, trauma exposed youth without PTSD, and non-traumatized youth using a three group case control design. The Children’s PTSD Inventory and unstructured DSM-IV based diagnostic interviews were utilized to determine diagnostic status. Given that prior research has indicated a relationship between neuroticism and internalizing disorders, and as PTSD is primarily an internalizing disorder, it was expected that youth with PTSD would have higher JEPI Neuroticism scores relative to trauma exposed youth without PTSD or case controls. It was further expected that JEPI Neuroticism scores of trauma exposed youth without PTSD and control subjects would not significantly differ. Finally, it was expected that JEPI Extraversion scores would not significantly differ between groups. As expected, youth with PTSD had significantly higher Neuroticism scores relative to traumatized youth without PTSD and controls. The Neuroticism scores of trauma exposed youth without PTSD and controls did not significantly differ. There were no significant differences between groups in regard to Extraversion scores. Implications for research and practice were considered.

Previous studies have suggested that mechanisms for neural compensation involve a reorganisation to right hemisphere processing in people with post-traumatic stress disorder (PTSD), and are associated with functional alterations in the capacity for behavioural flexibility. However, research has not established a direct relationship between the complex physiological and psychological processes of the heterogeneous disorder and right hemisphere cortical activity. The present study examined cognitive information processing in people with PTSD, reaction patterns associated with perceived traumatic stressors, and quantitative electroencephalographic (qEEG) indices of hemispheric asymmetry. Individuals with PTSD (N=34) and age and sex-matched normal controls (N=136) completed standardised web-based self-report questionnaires assessing traumatic stressor events and reaction patterns to those events. Neuropsychological indices of verbal, visuospatial, sensori-motor performance, and electrophysiological recordings, were examined for right hemisphere coding. The relationships among traumatic characteristic reaction patterns of numbing and avoidance, cognitive performance, and frontal and posterior EEG alpha asymmetry were also investigated. Structural and functional alterations were shown in those with PTSD, using indices of working memory for the retrieval of verbal and psychomotor information, indicating a reduced speed of processing and alterations to background cortical arousal in left hemisphere frontal regions. The study supported and extended previous findings of verbal working memory abnormality, alterations to left frontal cortical rhythmic oscillations, and low EEG alpha amplitudes in those diagnosed with PTSD. Results indicated a pattern of compensatory mechanisms associated with reduced speed of information processing and right-sided activation patterns in PTSD participants and control participants who experienced strong reactions to perceived traumatic events. Findings support the impact of traumatic events on psychobiological health in high-risk populations, implicating an association with specific patterns of neural and cognitive functioning in characteristic numbing and avoidance behaviours. / Thesis (Ph.D.) -- University of Adelaide, School of Population Health and Clinical Practice, 2008
