The Impact of Treatment Description Format on Patient Preferences for Posttraumatic Stress Disorder Treatment

The present study examined how the format in which treatment information is presented impacts individuals' preferences for posttraumatic stress disorder (PTSD) treatments. Adults who screened positive for PTSD (N = 301) were randomized into groups to learn about five first-line treatments; participants either read sequential text descriptions or reviewed a comparison chart that presented side-by-side information. Participants rated treatment acceptability, rank ordered treatments from most to least preferred, and indicated their confidence in this ranking. Compared with participants in the text group, those in the chart group assigned more favorable acceptability ratings to prolonged exposure therapy (PE) and more moderate ratings to medications. Cognitive processing therapy was the most common first-choice treatment (43.6%). Forced-choice treatment rankings were similar across conditions, although participants in the chart group ranked PE more favorably than those in the text group, odds ratio (OR) = 0.54, 95% CI [0.35, 0.82], p = .004. Confidence in treatment rankings did not differ across conditions. The results suggest that perceptions of treatment acceptability can be influenced by the format in which treatment information is presented. In settings where the goal is to increase treatment acceptability, side-by-side formats may offer an advantage over sequential descriptions of each treatment.
