This paper reports on the continuation of a study of 84
soldiers from two National Guard units (one medical, one military police)
who had served in the GW. Sixty two of the original 84 who were evaluated
at one and six months completed evaluations at 2 years. Depending upon

months. Scores for symptoms related to hyperarousal (especially startle
responses, sleep disturbance, and irritability) were significantly higher
than scores for symptoms associated with reexperiencing or avoidance.
Limitations of the study were the incompleteness of the study group, dropouts
at two years, reliance on self-reports, and a tendency for subjects to
