Prolonged exposure therapy (PE) is a gold standard psychotherapy that has been validated for military\/Veteran populations, has practical and clinical barriers, and has a moderate drop-out rate, in spite of its efficacy. Standard PE (SPE) involves 12-15 weekly sessions, while massed PE (MPE) involves daily sessions, typically offered over a two-week period. This case report examined the effectiveness and tolerability of MPE in a treatment-seeking Veteran. Baseline structured clinical interview and self-report questionnaire data were compared with post-treatment and follow-up data, with the primary outcome measure being the change in PTSD symptom severity on a structured clinical interview. MPE resulted in reduced PTSD and associated symptom severity as measured at the end of treatment and at follow-up. MPE was described as tolerable, despite short-term discomfort associated with the intense format, and beneficial in facilitating efficient and effective clinical change. This case report demonstrated the effectiveness and tolerability of MPE in a treatment-seeking Veteran. It raises attention for clinical innovation in evidence-based practice and encouragement for empirical replication of this finding in a larger, representative sample.<\/jats:p>","DOI":"10.3138\/jmvfh-2025-0032","type":"journal-article","created":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T13:34:56Z","timestamp":1775828096000},"page":"123-129","source":"Crossref","is-referenced-by-count":0,"title":["Effectiveness and tolerability of massed prolonged exposure therapy for PTSD in a CAF Veteran: A case report"],"prefix":"10.3138","volume":"12","author":[{"given":"Maya","family":"Roth","sequence":"first","affiliation":[{"name":"MacDonald Franklin OSI Research and Innovation Centre, London, Ontario, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1696","reference":[{"key":"r1","first-page":"4","volume":"61","author":"Kessler RC","year":"2000","journal-title":"J Clin Psychiatry"},{"issue":"11","key":"r2","doi-asserted-by":"crossref","first-page":"957","DOI":"10.3109\/00048674.2011.624083","volume":"45","author":"McEvoy PM","year":"2011","journal-title":"Aust N Z J Psychiatry"},{"key":"r3","volume-title":"Mental health in the Australian defence force: 2010 ADF mental health prevalence and wellbeing study: full report","author":"McFarlane A","year":"2011"},{"issue":"3","key":"r4","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1176\/ps.2007.58.3.357","volume":"58","author":"Sareen J","year":"2007","journal-title":"Psychiatr Serv"},{"issue":"1","key":"r5","doi-asserted-by":"crossref","first-page":"95","DOI":"10.1080\/09540261.2019.1595545","volume":"31","author":"Forbes D","year":"2019","journal-title":"Int Rev Psychiatry"},{"key":"r6","doi-asserted-by":"crossref","DOI":"10.1093\/med:psych\/9780195308501.001.0001","volume-title":"Prolonged exposure therapy for PTSD: emotional processing of traumatic experiences \u2014 therapist guide","author":"Foa EB","year":"2007"},{"issue":"9","key":"r7","doi-asserted-by":"crossref","first-page":"4192","DOI":"10.1017\/S0033291722000927","volume":"53","author":"Dell L","year":"2022","journal-title":"Psychol Med"},{"issue":"4","key":"r8","doi-asserted-by":"crossref","first-page":"354","DOI":"10.1001\/jama.2017.21242","volume":"319","author":"Foa EB","year":"2018","journal-title":"JAMA"},{"issue":"1","key":"r9","doi-asserted-by":"crossref","first-page":"1729633","DOI":"10.1080\/20008198.2020.1729633","volume":"11","author":"Lewis C","year":"2020","journal-title":"Eur J Psychotraumatol"},{"key":"r10","volume-title":"Australian guidelines for the prevention and treatment of acute stress disorder, posttraumatic stress disorder, and complex posttraumatic stress disorder,","author":"Australia Phoenix","year":"2020","edition":"3"},{"issue":"3","key":"r11","doi-asserted-by":"crossref","first-page":"397","DOI":"10.1016\/j.janxdis.2010.11.002","volume":"25","author":"Tuerk PW","year":"2011","journal-title":"J Anxiety Disord"},{"issue":"2","key":"r12","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1037\/a0026602","volume":"80","author":"Resick PA","year":"2012","journal-title":"J Consult Clin Psychol"},{"issue":"4","key":"r13","first-page":"392","volume":"12","author":"Sherrill AM","year":"2020","journal-title":"Psychol Trauma"},{"key":"r14","doi-asserted-by":"crossref","first-page":"1064478","DOI":"10.1016\/j.cct.2021.106478","volume":"107","author":"Dell L","year":"2021","journal-title":"Contemp Clin Trials"},{"key":"r15","volume-title":"The PTSD checklist for DSM-5 (PCL-5)","author":"Weathers FW","year":"2013"},{"issue":"18","key":"r16","doi-asserted-by":"crossref","first-page":"1737","DOI":"10.1001\/jama.282.18.1737","volume":"282","author":"Spitzer RL","year":"1999","journal-title":"JAMA"},{"key":"r17","first-page":"191","volume-title":"The use of psychological testing for treatment planning and outcome assessment.
