Background. Earthquake is a natural event that can happen all around the world. And significant ones would cause great fatality, morbidity and huge economic damage to the local society. Posttraumatic Stress Disorder (PTSD) is a common psychiatric condition among the earthquake survivors. Some former studies indicated that being female experienced a higher risk of depression, a psychiatric symptoms after traumatic events, while others did not. It is not sure that whether females tend to be more easily suffer from PTSD after earthquakes. So the aim of the study is to conduct a systematic review to examine the sex difference of PTSD prevalence among surviving population after earthquake. Method. A keyword searching was performed using ‘earthquake’ and ‘PTSD’, ’posttraumatic stress disorder’ as keywords. Articles published in recent 5 years, in English and the ones full text could be accessed were included in the study. Among the articles being selected according to the inclusion criteria, those ones which fulfilled the exclusion criteria would be eliminated. Results. 11 articles included in this systematic review. In terms of the age of the subjects, there are seven articles studying the adult population and the remaining four studied children and adolescents. Six articles investigated the survivors from Chinese population after 2008 Wunchuan earthquake. Others studied survivors from local population after 2005 Pakistan earthquake(n=2), 2007 Peru earthquake(n=1), 2009 L’Aquila earthquake(n=1) and 1999 Jiji earthquake (n=1). On the other hand, the sex difference in earthquake-related PTSD in children and adolescents were inconsistent. Conclusion. Women tended to experience higher risk of PTSD after earthquake than men, while result on sex difference was not consistent in the children/adolescent population. Further studies are needed to examine PTSD prevalence between boys and girls. / published_or_final_version / Public Health / Master / Master of Public Health

Background: Some women develop symptoms of posttraumatic stress following childbirth. There is preliminary evidence that cognitive variables may be associated with the development or maintenance of these symptoms. Research indicates that symptoms of posttraumatic stress following childbirth may have negative consequences for mother-infant relationship outcomes. However, these may be attributable to comorbid symptoms of depression. Further evidence is required regarding the nature of the relationships between these variables. Methods: An internet based cross-sectional questionnaire design was employed to test hypothesised relationships between maternal attachment experiences, metacognition, symptoms of PTSD and depression and perceptions of the mother-infant bond, in an analogue sample of new mothers. Structural equation modelling was employed for the principal analysis. Results: The final structural model demonstrated a good fit to sample data. Metacognition fully mediated the relationship between attachment experiences and postnatal psychological outcomes. The association between posttraumatic stress and maternal perceptions of the mother-infant bond was fully mediated by depression. Conclusions: Metacognition may have a key role in the development and maintenance of postnatal psychological distress. If clinically significant postnatal depression is identified, screening for posttraumatic stress is strongly indicated.

The study examined the effects of multiple interpersonal traumas (incurred simultaneously) on severity of PTSD symptoms; as demonstrated by the literature on the dose-effect relationship for PTSD, greater reports of interpersonal trauma, were hypothesized to lead to more severe PTSD symptomology. The 267 participants, were all Liberian war refugees living in Ghana, West Africa. Regression analysis was utilized to examine the contributions of interpersonal traumas (posttraumatic diagnostic scale), age, gender and marital status to PTSD symptoms (Impact of Event Scale). Interpersonal trauma was the strongest predictor, (β = .21, t(138) = 2.45, p < .05) of PTSD severity, which was supportive of the hypothesis. / Department of Psychological Science

Post-traumatic stress is a highly prevalent mental health condition. Mind-body interventions like yoga are increasingly being utilized in the treatment of PTS, but further research is needed to assess its effectiveness. This present randomized control study was designed to supplement the current field of inquiry with a relatively large group of participants and mixed method analysis of the data. The PTS symptoms and overall well-being of 50 participants enrolled in an eight-week trauma-specific Kundalini yoga (KY) program were examined. The findings demonstrate that KY may impact PTS symptomology, sleep, positive affect, perceived stress, and feelings of resilience. Eight month follow-up data are presented. Participant narratives are discussed corroborating quantitative findings and suggest that participants learnt tools to modulate emotions leading to self-mastery. Study limitations are presented with recommendations for future trauma-related research and practice.

This program of research investigated the nature and processes of autobiographical memory deficits in posttraumatic stress disorder (PTSD). Study 1 examined the proposition that difficulties in the retrieval of specific memories present a risk factor for posttraumatic psychopathology. A prospective study of fire-fighters found that a significant predictor of posttraumatic stress was a deficit in retrieving specific memories to positive cues before trauma. Study 2 investigated whether autobiographical retrieval deficits in PTSD can be modified by psychological treatment. Results found that as PTSD symptoms reduced following treatment, individuals with PTSD retrieved more specific memories to positive cues. Together, these results indicated that specific retrieval deficits to positive cues present a vulnerability factor for PTSD. However, this memory style appears to be receptive to modification following therapy. Study 3 investigated the association between autobiographical retrieval deficits and impaired problemsolving in PTSD. Participants with PTSD retrieved more overgeneral categoric memories and took longer to retrieve memories than non-PTSD trauma controls. This deficit was associated with impaired social problem-solving, suggesting that specific retrieval is related to successful problem solving. In an analogue design, Studies 4 and 5 investigated the proposition that resource limitations may underpin autobiographical retrieval deficits. Results generally supported the proposal that reduced cognitive resources may be a mechanism contributing to specific retrieval deficits. Studies 6 and 7 examined rumination as another possible mechanism responsible for these retrieval deficits. Study 6 found high anxious participants retrieved fewer specific memories to positive cues following rumination, compared to distraction. Study 7 found evidence that negative rumination in the high anxious group increased categoric retrieval, whereas positive rumination had no effect. Study 8 found retrieval of trauma-related self-defining memories was strongly associated with personal goals connected to the trauma. Study 9 found that discrepancies in one???s self construct were related to the retrieval of trauma memories to positive cues. This program of research extends current theories of autobiographical memory by identifying risk, maintenance, and recovery factors in the context of PTSD.
