News of an interesting Australian study, from PR Inside:
While a number of risk factors such as injury severity, demographic factors and compensation-related factors have been identified, none is strong enough to reliably predict which patient will develop the disorder. PTSD is characterized by flashbacks of the event, anxiety, and social withdrawal. Victims of major trauma are at significant risk of developing PTSD, with about 15% developing the disorder within a year of the injury.
A study in the July issue of ANZ Journal of Surgery titled 'Predictors of Post-Traumatic Stress Disorder following Major Trauma' by Professor Ian Harris et al. argues that the lack of consistency of previous PTSD studies is a result of methodological flaws such as selection bias, and poorly defined diagnostic criteria.
The authors investigated the association between injury severity, demographic and compensation-related factors with the development of PTSD and found that the disorder was also independently associated with having an unsettled compensation claim, their use of lawyer services and the placement of blame on others for the injury.
