cused cognitive behavioral therapy, cognitive processing therapy (CPT), and prolonged exposure therapy (PE). These are strongly recommended first-line therapies in major PTSD treatment guidelines. 9 Recently, Sloan and Marx' s 10 research team introduced a fivesession exposure-based PTSD treatment protocol called written exposure therapy (WET). WET is recommended for the treatment of PTSD in clinical practice guidelines (Department of Veterans Affairs/Department of Defense, 2017). Like other EBTs, it comprises critical components considered to be responsible for the successful treatment of PTSD symptoms, such as therapeutic exposure and cognitive processing/cognitive restructuring. [10][11][12] However, WET requires a smaller number of sessions, shorter session durations, and no between-session assignments. 10,13 The efficacy of WET was evaluated using a randomized controlled trial, and this study reported a significant reduction in PTSD symptom severity at the post-treatment follow-up, and symptom reduction was maintained three and six months later with 7% of drop-out rate. 14 A study that directly compared WET
