In the above mentioned article by Parker et al., on the seventh page, in the final paragraph of column two, the following three sentences should have been removed:
“DSM-IV criteria specify a minimum six-month delay between the traumatic event and a diagnosis of PTSD (APA, 2000). Any diagnosis prior to this time would be an acute stress reaction. Based on these diagnostic criteria, it is possible that at least two studies were reporting acute stress reaction rather than PTSD.”
This error does not change the results or conclusions of the study.
