The effect of cognitive processing therapy on cognitions: Impact statement coding


  • This research was funded by a grant from the National Institute of Mental Health (MH66324) awarded to Patricia A. Resick. Data were collected at the Center for Trauma Recovery, University of Missouri-St. Louis.


This study compared the cognitions of 37 female rape survivors before and after completing cognitive processing therapy (CPT). It was hypothesized that CPT would be associated with reductions in posttraumatic stress disorder (PTSD) symptoms and problematic (i.e., assimilated and overaccommodated) thoughts as well as increases in the number of realistic (i.e., accommodated) cognitions. Cognitions were assessed via coding and analyses of participants' written impact statements at the beginning and end of treatment. Posttraumatic stress disorder symptoms were assessed with the Clinician-Administered PTSD Scale and PTSD Symptom Scale. As predicted, there were significant increases in accommodated statements and significant decreases in overaccommodated and assimilated statements. The hypothesis that cognitive changes would be related to symptom reduction was partially supported.
