We provide commentary on the article by Austern (2017) in which several composite PTSD treatment cases with veteran clients are presented. Written Exposure Therapy (WET) was implemented in each case, with varying levels of success. We provide additional background on the development of WET to provide readers with a better understanding of how this treatment was created. We also describe the available efficacy data supporting the use of WET as well as describe efficacy studies that are currently underway. Lastly, we comment on Austern's use of WET in the three composite veteran cases that are described.Key words: PTSD; military combat; veterans; trauma; exposure therapy; composite case studies; clinical case studies
____________________________________________________________________________We read Austern's case study paper with great interest and are pleased to have an opportunity to comment. In this commentary, we first provide a background on how written exposure therapy (WET) was developed and describe the efficacy data to support its use. Following this, we will discuss the manner and methods in which WET was used by Austern. Throughout our commentary we will refer to the empirical data on PTSD treatment and the gaps in the literature, especially related to treating military service members and veterans.
DEVELOPMENT OF WETBecause only a partial description of the development of WET is provided by Austern, we want to describe how WET was developed, as well as offer the reader an understanding of the mechanism by which exposure-based treatments for PTSD work. A thorough description of the development of WET will enable a better understanding of the theoretical model underlying the treatment, which in turn provides a better understanding in the ways the treatment should and should not be altered.
