Introduction
When it comes to evidence-based trauma treatment, Eye Movement Desensitization and Reprocessing (EMDR) and Cognitive Processing Therapy (CPT) often stand out as the two most recommended first-line interventions. Both have strong research backing, are widely used in clinical settings, and are endorsed by organizations such as the U.S. Department of Veterans Affairs and the World Health Organization. But clinicians often ask: which one works better for PTSD?
This post compares EMDR and CPT head-to-head, highlighting mechanisms, strengths, limitations, and real-world case applications.

What Is EMDR?
- Developed by Francine Shapiro (1989)
- Utilizes bilateral stimulation (eye movements, taps, tones) to help reprocess stuck trauma memories
- Adaptive Information Processing model: trauma blocks natural healing; EMDR “unsticks” it
What Is CPT?
- Developed by Patricia Resick in the 1990s
- Structured CBT-based approach focused on challenging maladaptive trauma beliefs (e.g., self-blame, guilt, safety, trust)
- Core technique: identifying and restructuring “stuck points”
Research Evidence
EMDR
- Dozens of RCTs show EMDR reduces PTSD symptoms significantly
- Meta-analyses: often as effective as trauma-focused CBT, sometimes in fewer sessions (Cusack et al., 2016)
- Especially effective for single-incident trauma
CPT
- Strongest evidence base among CBT-based trauma therapies
- Effective across diverse populations: veterans, survivors of sexual assault, refugees
- Reduces not only PTSD but also depression and guilt (Resick et al., 2017)
Side-by-Side Comparison
| Feature | EMDR | CPT |
|---|---|---|
| Mechanism | Bilateral stimulation + memory reconsolidation | Cognitive restructuring of beliefs |
| Duration | 6–12 sessions typical | 12–16 sessions typical |
| Homework | Minimal | Extensive (worksheets, impact statement) |
| Client Fit | Visual/somatic learners, those avoiding homework | Analytical thinkers, clients with guilt/shame |
| Research | Equally effective as CPT (WHO, 2013) | Gold standard, particularly strong evidence for sexual assault survivors |
Case Vignettes
Case 1: EMDR Fit
“Carlos,” a combat veteran, struggled with flashbacks and hyperarousal. EMDR helped him process battlefield memories quickly. After 10 sessions, his PTSD symptoms dropped from severe to mild.
Case 2: CPT Fit
“Maya,” a sexual assault survivor, was paralyzed by self-blame. Through CPT’s worksheets and Socratic questioning, she reframed beliefs of guilt, achieving long-term improvement in both PTSD and depressive symptoms.
Clinical Decision-Making
- EMDR may be preferred for clients who are resistant to homework or struggle with avoidance
- CPT may be preferred when guilt, shame, and meaning-making are central issues
- Both can be sequenced: start with EMDR for rapid relief, then transition to CPT for deeper cognitive work
Conclusion
Neither EMDR nor CPT is categorically “better.” Both are highly effective, and choice should depend on client needs, preferences, and clinical context.
Bottom line for clinicians: Learn both approaches, understand client fit, and stay flexible.
