ABSTRACT
BACKGROUND: To date, there have been no studies comparing cognitive behavior therapy (CBT) with Rogerian therapy in post-traumatic stress disorder. METHOD: Sixty outpatients with DSM-IV chronic post-traumatic stress disorder were randomized into two groups for 16 weekly individual sessions of CBT or Rogerian supportive therapy (ST) at two centers. No medication was prescribed. Measures included the Post-Traumatic Stress Disorder Checklist Scale (PCLS), the Hamilton Anxiety Scale, Beck Depression Inventory, and Quality of Life. The general criterion of improvement (GCI) was a score of less than 44 on the PCLS. RESULTS: Forty-two patients were evaluated at post-test, 38 at week 52 and 25 at week 104. At post-test, the rate of patients leaving the trial due to worsening or lack of effectiveness was significantly higher in the ST group (p = 0.004). At this point, no between-group difference was found on the GCI and any of the rating scales. Intent-to-treat analysis found no difference for the GCI, but patients in the CBT group showed greater improvement on the PCLS and Hamilton Anxiety Scale. Naturalistic follow-up showed sustained improvement without between-group differences at weeks 52 and 104. CONCLUSIONS: CBT retained significantly more patients in treatment than ST, but its effects were equivalent to those of ST in the completers. CBT was better in the dimensional intent-to-treat analysis at post-test.

BACKGROUND: The Posttraumatic Stress Disorder Checklist Scale (PCLS) is a short self-report inventory for assessing the 3 main syndromes of Posttraumatic Stress Disorder (PTSD). The aim of this study was the validation of the French version of the PCLS in PTSD subjects and nonclinical subjects. METHODS: One-hundred and thirteen outpatients suffering from PTSD according to DSM-IV were administered the PCLS. The patients' scores on the PCLS were then compared to those of 31 nonclinical control subjects. Thirty-five of the patients were administered the PCLS twice over an interval of 1-2 weeks and also completed questionnaires measuring depression, phobia and anxiety. RESULTS: The patients' total score and subscores on the PCLS were found to be significantly higher than those of control subjects. The cutoff score of 44 on the French version PCLS distinguishes well between the PTSD group and control group with a high diagnostic efficacy (0.94). Factor analysis revealed 3 main factors corresponding to the reexperiencing, numbing and hyperarousal syndromes. The PCLS showed satisfactory test-retest reliability and internal consistency. CONCLUSIONS: The PCLS is therefore a valid and effective measurement of PTSD. It may be a useful tool for screening and assessing PTSD in psychiatric as well as in primary-care settings.
