Memory processes in posttraumatic stress disorderKenny, Lucy Margaret, Psychology, Faculty of Science, UNSW January 2006 (has links)
Current theories of PTSD propose that impaired retrieval of trauma memories may impede processing of these memories and subsequent trauma recovery. This thesis investigated memory retrieval processes in trauma survivors with and without symptoms of posttraumatic stress, and in non-traumatised individuals exposed to a highly arousing event. Study 1 examined deliberate avoidance of unwanted memories in recent trauma survivors. The results indicated that attempts to forget were associated with poorer recall of forgotten information, but the size of this effect did not depend on the presence or absence of Acute Stress Disorder (ASD). Study 2 investigated automatic retrieval inhibition in trauma survivors with or without Posttraumatic Stress Disorder (PTSD). The results suggested that repeated retrieval of trauma-related information by individuals with PTSD can cause inhibition of related, but unpractised information. Studies 3 and 4 examined the relationship between the vantage point of trauma memories, avoidance and posttraumatic stress symptomatology. The findings indicated that recalling a traumatic event from an observer perspective is associated with post trauma avoidance. They also showed that an observer vantage point in the initial few weeks after trauma is associated with poorer long-term post trauma adjustment. Studies 5, 6 and 7 were analogue studies which analysed the impact of heightened arousal on memory retrieval in novice skydivers. The results suggested that elevated arousal can interfere with retrieval of information related to the arousal-inducing event. Study 7 also indicated that autobiographical memory for the event may be impaired. Finally, Study 8 examined the qualities of trauma memories that were accessed via different modes of retrieval. The results provided evidence that intrusive memories were experienced as more realistic and with more intense affect than memories for the same event that were deliberately retrieved. Together, the findings of this program of research extend current theories of PTSD by highlighting the mechanisms through which retrieval of trauma memories may be impaired. The results suggest that the quality of trauma memories is affected by avoidance processes, elevated arousal and level of conscious control the individual exerts over retrieval.

Terapeuters arbete med krigsrelaterat posttraumatiskt stressyndromAvdic, Aida January 2007 (has links)
<p>Posttraumatiskt stressyndrom (PTSD) kännetecknas av tre huvudsymptom: undvikande, förnekande och hyperspändhet. Även koncentrationssvårigheter, ångest, depression, flashbacks och mardrömmar är vanligt förekommande hos individer med PTSD. Flyktingar i Sverige som har varit med om krig kan uppvisa dessa symptom. Syftet med denna studie är att undersöka terapeuters upplevelser av arbete med patienter med krigsrelaterat PTSD. Intervjuer med åtta terapeuter utfördes. Gemensamma mönster i deltagarnas svar var att det är fördelaktigt att skapa en bra relation till patienter. Det är viktigt att prata om krigstrauma och de som får behandling mår bättre. Patienter är präglade av sorg och skuld och det är viktigt för dem att känna tillit och trygghet. Kropp och själ hänger ihop och det är olika och beroende på många faktorer hur individer drabbas av krig. Ofta är det andra svåra upplevelser som förvärrar krigstrauma. Terapeuter upplever sitt arbete som roligt samtidigt som tungt och anser att det är viktigt med teamarbete.</p>

The relationship among cognitive appraisal, posttraumatic stress reactions and the experience of psychosisLiu, Chun-mei., 廖俊媚. January 2012 (has links)
The experience of psychosis (e.g. threatening symptoms such as persecutory delusion and terrifying hallucinations) and its treatment (e.g. coercive measures such as involuntary admission and seclusion) are distressing. In view of the potential severity of the distress associated with psychosis, previous research has applied the trauma model to understand the experience of psychosis and its treatment and found that 11-67% of psychotic patients presented with clinically significant PTSD reactions in response to their psychosis and treatment experience. This phenomenon is termed as post-psychotic PTSD (PP-PTSD). However, previous research generally failed to find consistent relationship between PP-PTSD reactions and objective psychotic and treatment experiences (except for positive psychotic symptoms). Cognitive conceptualization of PTSD opines that it is the cognitive appraisal of the traumatic event, rather than the trauma per se, that is related to the development of PTSD. The present study aims to contribute to a better understand of PP-PTSD through a cognitive perspective. The present study applies Ehlers and Clark’s cognitive model of PTSD in understanding PP-PTSD. It explores the roles of fear of relapse and perceived risk of relapse, attribution of the causes of psychosis, perceived stigma and rejection and perceived consequence of the psychotic illness in PP-PTSD. The present study was a cross-sectional study and recruited 38 patients with schizophrenia-spectrum disorders.
Semi-structured interview was used to determine whether the patients met the PP-PTSD diagnosis. The patient’s positive psychotic symptoms and social and occupational functioning were assessed by semi-structured interview while their PP-PTSD symptoms, trauma history and cognitive appraisals were measured using self-report questionnaires. Results showed that 15.8% of patients meet the full criteria of PP-PTSD and more than 50% of patients demonstrated some PP-PTSD reactions, which provides support for the application of the PP-PTSD construct in the local context. Treatment experiences were found to induce more severe PP-PTSD reactions than psychotic experience. Cognitive appraisals were found to be associated with PP-PTSD and there was some support for the application of Ehlers and Clark’s model in PP-PTSD. Specially, the present study found that fear of relapse, higher perceived risk of relapse, perceived helplessness and self-blame of causing the onset of psychosis, stable attribution of the cause of psychosis onset, perceived stigma, perceived large and chronic consequence of psychosis were all associated with more severe PP-PTSD reactions. Fear of relapse was also found to predict PP-PTSD severity. Clinical implications on the prevention, assessment and treatment with reference to the present results are discussed. / published_or_final_version / Clinical Psychology / Master / Master of Social Sciences
