Patients suffering from chronic PTSD were recruited into a study in which t
hey had to monitor and record in a diary their intrusive systems on a daily
basis for 4 weeks. Assessments were carried out before and after monitorin
g. Seventeen patients dropped out of the study during the monitoring period
, 12 patients no longer met criterion for PTSD, and 72 were still cases at
the second assessment. A comparison of improvers, cases, and dropouts indic
ated that improvers scored significantly lower on all assessment measures p
rior to monitoring, and were more likely to be employed than the other two
groups. Improvements made over the monitoring period were discussed.
