Abstract
The article shows the changes that were symptomatic among Colombian Police offi cers (7 men and one woman aged between 18 and 45) who had post-traumatic stress after an intervention process psychoanalytically oriented group psychotherapy. The psychotherapeutic process lasted 3 months with a frequency of 2 sessions per week and a duration of 1.30 hours per session. Symptomatic changes were assessed by Scale administered by the clinician (Clinician-Administered PTSD Scale, CAPS, Blake, Weathers, Nagy, Kaloupek, Charney and Keane, 1995) and individual clinical interviews. We found that in Police offi cers,some symptoms associated with Criterion B, C, D, and of the F scale, decreased, in others increased, and there were no other changes.
