What was helpful in today's session? Responses of clients in two different psychotherapies for posttraumatic stress disorder.

The aim of this study was to qualitatively analyze and compare the written responses clients in treatment for posttraumatic stress disorder (PTSD) gave when asked about helpful and negative aspects of the previous session. Data were collected during a randomized quantitative study comparing dialogical exposure therapy (DET, a gestalt-based integrative therapy, = 58) and cognitive processing therapy (CPT, a cognitive-behavioral therapy, = 52). We developed a coding manual using Mayring's (2015) qualitative content analysis approach and were able to code responses reliably.
