Objective This study examined clinical and retention outcomes following variable length prolonged exposure (PE) for posttraumatic stress disorder (PTSD) delivered by one of three treatment modalities (i.e., home‐based telehealth [HBT], office‐based telehealth [OBT], or in‐home‐in‐person [IHIP]). Method A randomized clinical trial design was used to compare variable‐length PE delivered through HBT, OBT, or IHIP. Treatment duration (i.e., number of sessions) was determined by either achievement of a criterion score on the PTSD Checklist for Diagnostic and Statistical Manual‐5 ( DSM‐5 ; PTSD Checklist for DSM‐5 ) for two consecutive sessions or completion of 15 sessions. Participants received PE via HBT ( n = 58), OBT ( n = 59) or IHIP ( n = 58). Data were collected between 2012 and 2018, and PTSD was diagnosed using the Clinician‐Administered PTSD Scale for DSM‐5 (CAPS‐5), administered at baseline, posttreatment, and 6 months following treatment completion. The primary clinical outcome was CAPS‐5 PTSD severity. Secondary outcomes included self‐reported PTSD and depression symptoms, as well as treatment dropout. Results The clinical effectiveness of PE did not differ by treatment modality across any time point; however, there was a significant difference in treatment dropout. Veterans in the HBT (odds ratio [OR] = 2.67; 95% confidence interval [CI] = 1.10, 6.52; p = .031) and OBT (OR = 5.08; 95% CI = 2.10; 12.26; p < .001) conditions were significantly more likely than veterans in IHIP to drop out of treatment. Conclusions Providers can effectively deliver PE through telehealth and in‐home, in‐person modalities although the rate of treatment completion was higher in IHIP care.
