Veterans' experiences of somatic experiencing and prolonged exposure therapies for post-traumatic stress disorder: A qualitative analysis.

Purpose: Despite the proliferation of research into evidence based treatment for military PTSD there is little evidence for treatment assignment criterion and military based PTSD still demonstrates low remission rates.

Method: Thirty participants in a randomized control trial comparing Prolonged Exposure (PE) and Somatic Experiencing (SE) were interviewed on their experiences in therapy and their responses assessed using a descriptive phenomenological analysis approach to delineate the central tenets of the two therapeutic approaches.

Results: Results indicated that participants from both therapies covered themes of the experience of change, the experience of the therapeutic relationship and the therapeutic process. Within these themes, SE and PE participants reported both similar experiences, such as the predominance of physiological or bodily experiences and also described nuanced differences, specifically pertaining to therapy characteristics. SE participants described the process in terms of learning a language, applicable to alternative scenarios and PE participants described the process in terms of conquering exposures in order to achieve respite from symptoms.

Conclusion: The current findings have relevance in terms of presenting the key elements of the distinct trauma therapies and determining treatment appropriateness based on desired outcomes. They highlight the commonalities and differences between the patient experience in PE and SE, specifically the relevance of the bodily response, treatment expertise and therapist characteristics in both treatments. Understanding the unique elements of PE, a gold-standard PTSD treatment and SE, a novel somatic-based psychotherapy, will allow for better treatment preparation for participants and potentially aid treatment assignment.
