Choosing the right trauma therapy can feel overwhelming, especially when symptoms of PTSD, anxiety, or unresolved trauma are disrupting your daily life.
Both Accelerated Resolution Therapy (ART) and Eye Movement Desensitization and Reprocessing (EMDR) use bilateral eye movements to help process traumatic memories, but they differ in structure, session length, and approach.
A 2024 systematic review found that ART delivered large symptom reductions in just a few sessions, while EMDR remains a well‑established, guideline‑supported therapy with decades of research backing its effectiveness.
This article will walk you through the evidence, ideal candidates, and practical differences to help you decide which therapy aligns with your needs and preferences.
What is EMDR and How Does It Work?
EMDR is a structured, eight‑phase trauma‑focused psychotherapy developed by Francine Shapiro in the 1980s. It is built on the Adaptive Information Processing model, which suggests that traumatic memories become “stuck” and can be reprocessed through bilateral stimulation, typically guided eye movements. The eight phases include history taking, preparation, assessment, desensitization, installation of positive beliefs, body scan, closure, and reevaluation.
The 2025 American Psychological Association guideline for adult PTSD positions EMDR as a suggested treatment, with cognitive processing therapy, prolonged exposure, and trauma‑focused cognitive behavioral therapy receiving the strongest recommendations. EMDR is widely recognized by international bodies and has been shown in multiple systematic reviews to be effective and cost‑effective for PTSD, with outcomes comparable to other trauma‑focused therapies.
Sessions typically last 60 to 90 minutes, and the total number of sessions varies based on the complexity of the trauma. Some clients complete treatment in six to twelve sessions, while those with complex or multiple traumas may require extended care. EMDR does not require homework, though between‑session processing and self‑care are encouraged.
What is ART and How Does It Differ?
Accelerated Resolution Therapy was created by Laney Rosenzweig in 2008 as a derivative of EMDR. ART integrates imaginal exposure, imagery rescripting, and guided bilateral eye movements with a directive, rapid protocol designed to replace distressing images with positive ones. A key feature is that clients are not required to verbally recount trauma details, which can reduce perceived retraumatization and increase acceptability for those reluctant to narrate their experiences.
ART is typically delivered in one to five sessions, often averaging around four sessions in published studies. A 2018 commentary in a VA/DoD‑focused journal noted that ART had one randomized controlled trial and multiple observational studies at that time, with high provider satisfaction and alignment with trauma‑focused treatment elements. The therapy emphasizes client control, positive affect induction, and no homework, making it appealing in settings where brevity and minimal disclosure are priorities.
However, ART’s evidence base remains smaller and more heterogeneous than EMDR’s. A 2024 systematic review of ART for adult PTSD included five studies with 337 enrolled participants and found large pre‑to‑post symptom reductions, but heterogeneity and risk of bias precluded meta‑analysis. Importantly, no head‑to‑head trials comparing ART and EMDR have been published, leaving comparative effectiveness uncertain.
Comparing Effectiveness: What Does the Evidence Show?
EMDR has been evaluated in numerous randomized controlled trials and meta‑analyses. A 2025 review of reviews summarizing systematic reviews and meta‑analyses since 2019 confirmed that trauma‑focused psychological interventions, particularly trauma‑focused CBT and EMDR, retain strong support for efficacy and cost‑effectiveness. EMDR has been shown to produce large reductions in PTSD symptoms, with effects maintained at six‑month follow‑up and outcomes comparable to prolonged exposure and cognitive processing therapy.
For example, a multicenter randomized trial of EMDR for fear of childbirth in pregnant women found large within‑group symptom reductions and no safety concerns, though EMDR was not superior to care‑as‑usual in that specific context. This underscores that while EMDR is effective, the choice of comparator and implementation setting matter.
ART’s evidence is more limited. The 2018 VA/DoD commentary described one RCT in U.S. service members and veterans, which showed significantly greater reductions in self‑reported PTSD, depression, anxiety, and trauma‑related guilt compared to an attention control condition, with a 94% completion rate over an average of 3.7 sessions. Effects were maintained at three months. Additional cohort studies have reported large pre‑to‑post improvements, but the absence of head‑to‑head trials with EMDR or trauma‑focused CBT limits definitive conclusions about comparative effectiveness.
Dropout, Acceptability, and Patient Preference
High dropout rates are a recognized challenge across PTSD psychotherapies. The 2025 review of reviews highlighted that while EMDR and trauma‑focused CBT are effective and cost‑effective, dropout remains a persistent issue, and few head‑to‑head trials exist to guide comparative decisions.
Acceptability can differ even when symptom outcomes are similar. An interim analysis from a multisite RCT comparing trauma‑sensitive yoga to cognitive processing therapy in women veterans with military sexual trauma‑related PTSD found that both interventions produced large symptom reductions, but yoga had higher completion rates (60.3% vs 34.8%) and earlier symptom improvement. This illustrates that treatment structure, perceived burden, and patient preference can significantly influence engagement and retention.
ART’s non‑narrative approach, lack of homework, and brevity may enhance acceptability for clients who are reluctant to disclose trauma details or who have limited time or tolerance for longer protocols. EMDR’s established status, guideline endorsement, and broader clinician availability may appeal to those prioritizing a well‑supported, recognized therapy. Adjuncts like the Flash Technique, a preparation‑phase intervention derived from EMDR that reduces distress without active recollection, can further improve tolerability for highly reactive clients.

Who is the Ideal Candidate for Each Therapy?
EMDR may be a strong fit when:
- You prefer a well‑established trauma‑focused therapy with guideline support and decades of research.
- Full trauma processing, including narration and sequential reprocessing, is feasible and acceptable.
- You have access to an experienced EMDR clinician and are open to a structured, multi‑phase protocol.
- You value a therapy with demonstrated cost‑effectiveness and broad international recognition.
ART may be preferable when:
- You are reluctant or unwilling to recount trauma details and value a high sense of control in‑session.
- You need or prefer ultra‑brief intervention, with meaningful results often achieved in one to five sessions.
- Homework or between‑session assignments are barriers to engagement.
- You are in a setting where rapid symptom reduction is a priority, such as military or veteran contexts, and are comfortable with a therapy that has a smaller but promising evidence base.
Special considerations:
- Pregnancy: EMDR has been shown to be safe in pregnancy for fear of childbirth, though not superior to care‑as‑usual in that trial. ART safety data in pregnancy are limited in peer‑reviewed sources.
- Complex trauma and comorbidity: The 2025 APA guideline emphasizes outcomes including dissociation, affect dysregulation, and suicidal ideation. Both therapies should be evaluated on these broader endpoints in future research.
Typical Treatment Structure and Session Flow
EMDR follows an eight‑phase protocol:
1. History and treatment planning
2. Preparation (may include the Flash Technique to reduce pre‑processing distress)
3. Assessment (target image, negative cognition, distress level, validity of positive cognition)
4. Desensitization (bilateral stimulation while reprocessing)
5. Installation (strengthening positive cognition)
6. Body scan (identifying residual somatic disturbance)
7. Closure
8. Reevaluation
Session count varies widely. Complex presentations often require extended courses, while single‑incident traumas may resolve in fewer sessions. EMDR can be delivered individually or in groups, and with adaptations for recent events.
ART typically progresses through:
- Brief history and target selection, without requiring trauma narration.
- Guided horizontal eye movement sets with a focus on calming and imagery change.
- Therapist‑guided imagery rescripting to replace distressing images with positive ones while monitoring somatic responses.
- Integration and future template (varies by protocol).
ART frequently claims one to five sessions to meaningful results, often averaging around four in published studies through 2018. It does not require homework.
Flash Technique is typically inserted into EMDR’s preparation phase and can also be used with other trauma‑informed treatments. A session often involves identifying a target, then focusing predominantly on a positive, engaging image while periodically “flashing” attention in brief, controlled intervals—paired with bilateral stimulation or tapping—such that the target’s distress falls without direct, sustained focus on the trauma.

What the Research Gaps Mean for You?
The most significant gap in the current evidence is the absence of head‑to‑head randomized controlled trials comparing ART and EMDR. The 2025 review of reviews explicitly calls out the dearth of head‑to‑head comparisons with established treatments and notes the rapid proliferation of novel interventions with low‑quality evidence.
Until such trials are conducted, EMDR remains the default evidence‑based choice when prioritizing guideline‑concordant, well‑established efficacy with predictable training and support infrastructure. ART is a rational, patient‑centered option when specific acceptability and feasibility criteria are paramount, such as reluctance to narrate trauma, high dropout risk, or system constraints requiring ultra‑brief delivery.
Future trials should use standardized patient‑reported outcome measures like the PTSD Checklist (PCL‑5), include adherence and dropout as co‑primary endpoints, assess broader outcomes such as dissociation and affect dysregulation, and incorporate cost‑effectiveness analyses. Such research would provide the comparative data needed to refine clinical decision‑making and health system planning.
A Practical, Stepped Approach to Choosing
Start with guideline‑preferred options like cognitive processing therapy, prolonged exposure, or trauma‑focused CBT when feasible and acceptable to you, as these have the strongest evidence base in the 2025 APA guideline. Offer EMDR as a suggested therapy with established cost‑effectiveness and a robust evidence base.
Consider ART when you refuse to narrate trauma details or find exposure intolerable, when brief dosing is required by clinical or system constraints, or when engagement risk is high and acceptability must be maximized. In such cases, ART’s non‑narrative and brief structure may be an advantage, though you should set expectations about the relative maturity of the evidence base.
Augment EMDR with the Flash Technique in the preparation phase to enhance tolerability for highly reactive patients, potentially reducing dropout risks. Incorporate your values and preferences explicitly, aligned with the 2025 APA guideline emphasis on applicability across diverse contexts and broader outcomes beyond PTSD symptoms.
Safety and Medical Considerations
EMDR cautions include epilepsy, severe substance use, certain neurological conditions, and pregnancy, among others. These lists urge clinical care, not categorical avoidance. The fear of childbirth trial indicates EMDR’s safety in pregnancy in that specific context.
ART’s non‑narrative and calming elements may reduce acute distress during sessions. Formal contraindication lists were not available in the provided peer‑reviewed sources, so standard trauma‑informed precautions apply: monitor distress and dissociative activation, and use stabilization strategies as needed.
Both therapies should be delivered by trained clinicians with appropriate supervision and fidelity monitoring. EMDR training and supervision are well‑established within professional networks. ART training availability is growing, with high provider satisfaction reported in VA/DoD contexts.
Making Your Decision
Both ART and EMDR offer pathways to healing from trauma, anxiety, and PTSD, but they differ in evidence maturity, structure, and acceptability features. EMDR is the more established option, with guideline recognition, decades of research, and demonstrated cost‑effectiveness. ART is a promising, efficient alternative that may be particularly well‑suited to clients who prioritize brevity, minimal disclosure, and no homework.
Your choice should be guided by your personal preferences, the severity and complexity of your symptoms, your tolerance for trauma narration, and the availability of trained clinicians in your area. A collaborative conversation with a qualified mental health provider can help you weigh these factors and select the therapy that aligns with your goals and circumstances.
