Although there is a range of effective posttraumatic stress disorder (PTSD) treatments, the number of patients who receive those treatments is disappointingly low (Finley et al., 2015; Maguen et al., 2018). Very little research has examined the patient experience of deciding on a PTSD treatment option and how that experience influences treatment preference and selection. In a sample of 12 veterans and 10 providers, we recorded the sessions in which providers discussed PTSD treatment options with their patients and then interviewed patients to ask their impressions of those same sessions. Specifically, using qualitative analysis, we sought to understand (a) patient preferences and experiences of choosing a PTSD treatment option, (b) what information patients retain from treatment planning sessions, and (c) why patients chose a given treatment. Almost all the patients in this sample chose an evidence-based psychotherapy but could remember little about the options afterward. Patients reported that providers presented options neutrally and that they made shared decisions with their providers. Most could talk through their reasons for coming to a decision and felt comfortable with the decision, but decisions were often made heuristically rather than deliberatively. Surprisingly, a few patients had a hard time explaining why they chose a specific treatment, were not conscious of their exact reasons for choosing a treatment, or seemed unable to remember why they chose a treatment. We also noticed subtle ways in which providers' discussions influenced treatment choice. Implications for practice are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
