A study of posttraumatic stress in a student population.

The authors examined the incidence of posttraumatic stress (PTS), with respect to levels of exposure to traumatic events, in a British student population. Respondents (N = 700) completed a standard questionnaire booklet that contained a posttraumatic stress disorder interview. The questionnaire collected personal demographic information and was used by researchers to ascertain whether respondents had experienced a traumatic event. Consistent with previous American studies, PTS was found to be relatively common; 23.3% of the sample showed either current or past PTS. Female participants had a significantly higher incidence of PTS than did male participants, although the latter were more likely to report having experienced a traumatic event. The experience of trauma was significantly associated with the likelihood of PTS. The authors discuss implications of their results in terms of long-term consequences of unresolved trauma.
