• W98394715 abstract "Exposure to a traumatic event may result in the development of PosttraumaticStress Disorder (PTSD) or Acute Stress Disorder (ASD). Biopsychosocial variablesassociated with these disorders following motor vehicle accident [MVA] trauma were thesubject of this investigation. Reviews of the diagnostic classification of the psychologicalsequelae of trauma exposure, and theoretical models of the aetiology of posttraumaticstress disorders preceded the empirical studies. Posttraumatic responses were concludedto be affected by multiple biopsychosocial mechanisms best represented by an integratedaetiological model. Consequently, the need for multimodal assessment of posttraumaticpsychological responses was evident, and existing assessment methods were discussed.ASD was found to be the subject of relatively little research to date when compared withPTSD, highlighting a need for comprehensive examination of the more recently introduceddiagnostic entity.The empirical studies focused on the examination of multi-variable profilesassociated with diagnosis-specific psychological sequelae to MVA trauma. The first studywas a large scale screen of an Australian university student sample (N = 425), and wasconducted to investigate MVA trauma exposure and associated posttraumatic symptoms.In the second study, psychometric data were used to investigate coping styles and beliefsystems associated with the development of PTSD, ASD and subclinical responses toMVA trauma (N = 83). The results indicated little difference in the profiles of the ASDand subclinical groups, which were characterized by adaptive coping and rational belief systems. The PTSD group profile was characterized by a combination of adaptive andmaladaptive coping, and no differences were found between the three groups in terms ofrationality of beliefs. Study three demonstrated the use of a multimodal tool to assessassociations between recollections of peritraumatic responses and posttraumatic diagnosticoutcomes. Psychological and psychophysiological reactivity to trauma-related and neutralidiosyncratic imaged events were examined using a four stage guided imagerymethodology (N = 51), and multimodal group-specific response patterns were detected.Study four investigated perceived posttraumatic psychological outcomes of the threeexperimental groups (N = 83). The ASD and subclinical group profiles reflected adaptiveand positive posttraumatic recovery, but also reflected that all participants, regardless ofdiagnosis, were psychologically affected by MVA exposure. The PTSD group profile wascharacterized by a broad range of negative posttraumatic outcomes, pervasive in manyaspects of functioning. Consideration was given to factors that may have led to thesebetween group differences.The results of the empirical studies supported the proposition that PTSD and ASDare distinct diagnostic entities that may be differentiated on the basis of a complex array ofbiopsychosocial variables. The implications of the results for the assessment, diagnosis andtreatment of posttraumatic responses were discussed, and directions for future researchwere suggested." @default.
