Evidence-Based

1 Rapid outcomes

(average of 3–4 sessions; as few as 1)

• In a randomized controlled trial of combat-related PTSD (Military Medicine, 2013; N = 57), participants achieved large reductions in symptoms of PTSD after a mean of 3.7 sessions (Kip et al., 2013a).
• A community-based civilian trial (Behavioral Sciences, 2012; N = 80) likewise showed substantial reductions in symptoms of PTSD within one to five ART sessions (Kip et al., 2012).
• A veteran cohort including community residents and residents of a homeless shelter (Nursing Outlook, 2016; N = 117) reported large, comparable reductions in symptoms of PTSD (Kip et al., 2016).
• Brief treatment courses with ART have consistently produced durable results, with sustained well-being demonstrated in follow-up work (OMEGA – Journal of Death & Dying, 2022; Belew et al.).

2 Effectiveness in PTSD

ART produces clinically significant and lasting reductions in PTSD and comorbid symptoms across both military and civilian settings:

• In a randomized controlled trial published in Military Medicine (2013), ART recipients (vs. an attention control group) showed significantly greater reductions in symptoms of PTSD, depression, anxiety, and trauma-related guilt immediately post-treatment and at 3-month follow-up.
• In a randomized trial for complicated grief (Journal of Aging & Health, 2020; N = 54), participants demonstrated broad reductions in PTSD, grief, and depressive symptoms (Buck et al., 2020).
• A Military Medicine (2023) subgroup analysis of data from an earlier ART veteran cohort found significant PTSD symptom improvement among participants, including those previously treated with Cognitive Processing Therapy (CPT).

3 Broad symptom impact

(depression, grief, comorbidity)

Across multiple peer-reviewed investigations, ART alleviates co-occurring depression, anxiety, and grief alongside trauma relief:

• In a 2013 prospective cohort trial (Kip et al., 2013b; N = 80), participants exhibited significant reductions in both PTSD and depressive symptoms after ART.
• In a randomized controlled trial of ART in complicated grief (Journal of Aging & Health, 2020; N = 54) participants demonstrated significant improvements in emotional well-being and daily functioning.
• In an observational study of veterans (Nursing Outlook, 2016; N = 117) subjects demonstrated multi-domain benefits, including reduced anxiety and improved sleep quality.

4 Sustained / durable effect

Across multiple peer-reviewed publications, ART was shown to alleviate symptoms of depression, prolonged grief, and anxiety:

• A randomized controlled trial in complicated grief (Journal of Aging & Health, 2020) showed significant symptom reduction, with an observation follow-up (OMEGA – Journal of Death & Dying, 2022) documenting maintenance of gains and higher life satisfaction over time.
• In military populations, symptom reductions persisted for at least six months post-intervention (Military Medicine, 2015; N = 80).
• In cohort studies of diverse clinical populations (Kip et al., 2012–2016) researchers reported similar durability of outcome without need for extended treatment courses.
