<meta content="Psychological  trauma results from exposure to an inescapable stressor  that overwhelms  a person's  ability to cope.  During the period of perceived threat a  defensive process of denial and suppression frequently operates to  control  a person's  emotional response to the situation.  Emergency services personnel in particular, may actively employ a task-  oriented approach to traumatic incidents: and suppress their anxiety and  fear in order to maintain concentration  and undertake their duties most effectively.  In psychological terms, this behaviour may be seen as purposeful, adaptive dissociation.   However, recent studies of emergency services personnel reveal that there are possible long-term risks associated with the experiencing dissociation  during a traumatic situation. While the ability to control emotional response may be viewed as an effective way  of coping during an intense or traumatic situation, there is an inherent danger that this inhibition of emotions may become the source of long term psychological and physiological disturbance.   Psychological  debriefing is a popular method of assistance for emergency services personnel following a traumatic incident.  It is designed to promote the cognitive and emotional processing of a traumatic event.  During a debrief,  participants describe the traumatic experience (including their reactions and emotions) in order to begin to  integrate and master key features of the experience.   While there is abundant anecdotal evidence suggesting that psychological  debriefings can be beneficial, there have also been conflicting reports as to their actual effectiveness. Investigators have indicated that rigorous  investigation of the effectiveness of psychological  debriefing and its role in post-trauma recovery is urgently  required.  In  particular, such investigations need to provide a clear answer to the  question 'Is psychological  debriefing related to the prevention of PTSD  symptoms and associated psychological sequelae?'      In this study, an investigation was undertaken of 96 emergency services  personnel  involved in the response to the 'Port Arthur massacre', a critical incident  in which a lone gunman randomly killed 32 visitors in a popular tourist  venue in southern Tasmania. All participants were individually interviewed on two occasions: eight  months after and twenty months after the incident.  Two key findings from  the research project we presented.  Firstly, experiencing dissociative symptoms at the time of the incident was predictive of long-term psychological  and physiological distress. Secondly, within the group of emergency services personnel who experienced  dissociation at the event, those who disclosed their related thoughts and  feelings at the subsequent group debriefings showed significantly less  long-term psychological distress. The results of this study offer insight into how the impact of biological  chances caused  by a traumatic event can be modified by the psychological processing of  that event.  The results support the suggestion that following a traumatic situation, a person needs to process and integrate the memory of that event if he or she is to 'recover'   from his or her reaction to the situation.  Psychological debriefing  appears to provide an opportunity for the necessary psychological processing to commence and assist emergency  services personnel in managing what might otherwise develop into PTSD.

During the period of perceived threat a  defensive process of denial and suppression frequently operates to  control  a person's  emotional response to the situation.  Emergency services personnel in particular, may actively employ a task-  oriented approach to traumatic incidents: and suppress their anxiety and  fear in order to maintain concentration  and undertake their duties most effectively.  In psychological terms, this behaviour may be seen as purposeful, adaptive dissociation.   However, recent studies of emergency services personnel reveal that there are possible long-term risks associated with the experiencing dissociation  during a traumatic situation. While the ability to control emotional response may be viewed as an effective way  of coping during an intense or traumatic situation, there is an inherent danger that this inhibition of emotions may become the source of long term psychological and physiological disturbance.   Psychological  debriefing is a popular method of assistance for emergency services personnel following a traumatic incident.  It is designed to promote the cognitive and emotional processing of a traumatic event.  During a debrief,  participants describe the traumatic experience (including their reactions and emotions) in order to begin to  integrate and master key features of the experience.   While there is abundant anecdotal evidence suggesting that psychological  debriefings can be beneficial, there have also been conflicting reports as to their actual effectiveness. Investigators have indicated that rigorous  investigation of the effectiveness of psychological  debriefing and its role in post-trauma recovery is urgently  required.  In  particular, such investigations need to provide a clear answer to the  question 'Is psychological  debriefing related to the prevention of PTSD  symptoms and associated psychological sequelae?'      In this study, an investigation was undertaken of 96 emergency services  personnel  involved in the response to the 'Port Arthur massacre', a critical incident  in which a lone gunman randomly killed 32 visitors in a popular tourist  venue in southern Tasmania. All participants were individually interviewed on two occasions: eight  months after and twenty months after the incident.  Two key findings from  the research project we presented.  Firstly, experiencing dissociative symptoms at the time of the incident was predictive of long-term psychological  and physiological distress. Secondly, within the group of emergency services personnel who experienced  dissociation at the event, those who disclosed their related thoughts and  feelings at the subsequent group debriefings showed significantly less  long-term psychological distress. The results of this study offer insight into how the impact of biological  chances caused  by a traumatic event can be modified by the psychological processing of  that event.  The results support the suggestion that following a traumatic situation, a person needs to process and integrate the memory of that event if he or she is to 'recover'   from his or her reaction to the situation.  Psychological debriefing  appears to provide an opportunity for the necessary psychological processing to commence and assist emergency  services personnel in managing what might otherwise develop into PTSD. </p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Thesis (PhD)</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Mental healing, Dissociative disorders, Dissociation (Psychology), Post-traumatic stress disorder, Mass murder -- Tasmania -- Port Arthur.</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/380100.html">380000 Behavioural and Cognitive Sciences &gt; 380100 Psychology</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1271</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Eprints Repository Manager</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">26 Jun 2007</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">09 Jan 2008 02:30</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=1271;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=1271">item control page</a></p>
