Flash Technique

Philip Manfield · 2016
Key text: Manfield et al. (2017)
Trauma-Focused Focus: Processing Short-term Individual

Core Mechanism

Brief interrupted exposure with positive memory engagement reprocesses disturbing memories without full activation

Ontology

Same AIP model as EMDR — dysfunctionally stored trauma memories

Therapeutic Voice

"Think of your peaceful place. Keep that in mind while I tap. Let me know if anything shifts."

View of the Person

A processing system that can reprocess disturbing memories without full conscious activation


Evidence

Not listed

1-2 pilot studies

None

Emerging. Used within EMDR framework. Very limited published research. Controlled evidence insufficient.

PTSD & Acute Trauma
Effect: Preliminary RCT positive
Rapid SUD reduction in sessions
Manfield et al., 2017 (2017)

Conditions

Epistemology

EmpiricistPragmatist

Blind Spots

Extremely new; minimal independent replication; unclear when minimal-activation processing is insufficient

Contraindications

Active psychosis, clients without a positive memory or image to use as a resource, unstable dissociative disorders, situations requiring full trauma narrative processing rather than distress reduction


Training

Flash training workshop (1-2 days). EMDR or trauma processing background recommended

No formal certification; authorized trainers

8-16 hrs

$300-800


Philosophical Roots

Same AIP model as EMDR; reconsolidation theory (Nader, 2000); titration principle from somatic traditions

Controversies & Ethical Concerns

Emerging evidence base: 1 RCT (Yasar et al., 2022), multiple preliminary studies, ENHANCE RCT in progress. Mechanism not yet empirically validated but theoretical proposals published.

2017–present sci

Flash Technique was introduced in 2017 and has an emerging but limited evidence base: one RCT (Yasar et al., 2022), several preliminary studies, and an ongoing multisite RCT (ENHANCE). The proposed mechanism — brief, interrupted exposure combined with positive engagement to reduce traumatic memory disturbance without significant distress — has not been empirically validated. The technique has gained rapid adoption among trauma therapists despite the evidence base being in early development.

Developers and proponents note that the technique emerged from clinical EMDR practice and that research is actively in progress. The ENHANCE RCT is designed to provide more rigorous evidence. They argue that the technique's low-distress profile makes it a valuable option for clients who cannot tolerate standard exposure-based approaches, even while research continues.

Test Yourself

How does Flash differ from EMDR?

Show answer

Client focuses on pleasant memory with brief 'flashes' to target — minimal distress.
