Group EMDR Approaches
Group EMDR refers to a family of adaptations delivered to several participants together. The term does not identify one uniform protocol. A group intervention may focus on recent traumatic events, ongoing stress, preparation or other targets, and the evidence should be attached to the specific procedure studied.
Why a group format?
Group approaches have been investigated in settings where many people share exposure to disaster, displacement or other stressful circumstances and individual treatment resources are limited. Some use worksheets or self-administered tactile stimulation and do not require participants to describe their experiences publicly. The exact requirements depend on the protocol. 1) 2)
Group delivery creates its own clinical questions: how participants are selected, how an individual's distress is noticed, what happens if someone needs separate support, and how confidentiality is managed. A group size or schedule used in a research project is not automatically appropriate for every setting.
A refugee study
Yurtsever and colleagues' 2018 randomised study examined an EMDR Group Traumatic Episode Protocol (G-TEP) intervention with Syrian refugees. The report describes 47 participants in the experimental and control groups, with assessments before, after and four weeks following intervention. It reported improvements in traumatic-stress and depression outcomes in the intervention group. 3)
This is evidence about a particular protocol in a particular context. The small sample and short follow-up constrain conclusions, and a comparison with an untreated control does not establish superiority to another active group therapy. The paper's participant flow and unequal final group sizes also matter when interpreting its summary results.
Other forms of group work
Gonzalez-Vazquez and colleagues studied a group programme for complex trauma and dissociation combining psychoeducation with selected EMDR procedures. Its case-control design compared this with psychoeducation alone and reported advantages on some outcomes. It was not a randomised test of standard individual EMDR delivered simultaneously to a group. 4)
Lazzaroni and colleagues described remote group work with adolescents and young adults during the first COVID-19 lockdown. Participants reported improvement on several pre/post measures. Without a concurrent control, that study primarily informs feasibility and preliminary outcomes rather than isolating a treatment effect. 5)
Reading group evidence
Research summaries should name the protocol, participant population, delivery setting, comparator and follow-up. They should also distinguish improvement within a group from a difference between groups. Pooling unlike procedures under the single heading 'group EMDR' can conceal clinically important variation.
Group Flash studies belong to a related but distinct literature. Likewise, group EMDR evidence does not establish the effectiveness of group IEMT or EMI without direct studies of those approaches.
