When EMDR is not working: nonresponse, dropout, review, and next decisions

A 2024 meta-analysis of 86 studies and 7,894 participants estimated 39.23% nonresponse across first-line psychological PTSD treatments, with substantial heterogeneity and half of studies at high risk of bias. Its EMDR subgroup estimate was lower, but subgroup and study limitations prevent a promise about an individual client.

Nonresponse can mean failure to reach a chosen symptom reduction, reliable change or diagnostic cutoff. Those definitions are not interchangeable. No movement in one SUD rating, an incomplete target, persistent comorbidity and no meaningful overall improvement are different clinical observations.

A systematic review estimated 16% pooled dropout from randomized PTSD psychotherapy trials, with wide variation. An earlier review of 55 studies showed inconsistent definitions and nonresponse rates sometimes reaching 50%, making simple comparisons between therapies unreliable.

Leaving treatment can reflect burden, access, cost, timing, therapeutic relationship, preference, adverse effects, life disruption, safety or lack of benefit. It does not prove that the person was unmotivated, that EMDR caused harm, or that treatment would have succeeded if attendance continued.

Reassess diagnosis, goals, risk, current threat, dissociation, health, substances, sleep, medication, alliance, consent, target formulation, preparation, fidelity, accessibility, session frequency, between-session effects and objective functioning. Ask the person's account directly and compare it with agreed measures.

Distinguish an in-session block from a course-level pattern. Consultation may identify protocol drift or missing information, but supervision should not be used to pressure continuation. Document uncertainty, benefits, burdens, alternatives and the rationale for continuing, adapting, pausing, referring or ending.

Use repeated measures consistently enough to see trajectory while checking whether the instrument fits the problem and language. A score can miss quality of life, avoidance, relationships, work, safety and personally important change; apparent improvement can also coexist with serious risk.

EMDRSuite can store dated ratings, targets and notes for review. It does not diagnose nonresponse, predict dropout, recommend interweaves, alter a protocol, select another treatment or decide termination. The therapist and client make those decisions within competence and local standards.
