“WET Trauma Therapy: Evidence‑Based Treatment for PTSD”

I am often asked if I do EMDR or a specific type of trauma therapy. My answer is that it depends upon the client, their experience and their needs. There is never a one-size-fits-all approach in therapy in my opinion because every client has different needs, personality, and willingness to participate. (And I don't do EMDR)

So, while there isn’t a single “most effective” trauma therapy for everyone, there are a few that consistently sit at the top of the evidence based research. These include Prolonged Exposure (PE) which is repeated imaginal and in-vivo exposure, Cognitive Processing Therapy (CPT) which is challenging trauma-related beliefs, Eye Movement Desensitization and Reprocessing (EMDR) which is memory activation and bilateral stimulation with eyes, and Written Exposure Therapy (WET) which is exposure support through writing.

The effectiveness of these treatments depends on what fits best with the person.

• PE: best if someone is willing to do intensive exposure and homework.

• CPT: great if they’re stuck in guilt, shame, or “stuck points” in their thinking.

• EMDR: often preferred by people who like experiential work and less verbal detail.

• WET: strong option when time, burden, or avoidance make longer treatments hard.

The reason I will choose WET for some clients is when they need a shorter, simpler, lower‑burden, and more tolerable trauma treatment. If the barrier is intensity, time, avoidance, or emotional overwhelm, WET is often the more effective choice because clients actually complete it.

So, let me explain it a little more.

Written Exposure Therapy (WET) is a brief, structured PTSD treatment where a person writes in detail about a traumatic experience across five sessions, helping reduce fear and distress linked to the memory. It’s designed to be simple, efficient, and highly accessible, with minimal therapist intervention.

1. Write about the same traumatic event each session

You choose one specific event, not a general theme or a series of events. The goal is deep processing, not broad coverage.

2. Write in the first person, present tense

This helps you re‑experience the memory rather than describe it from a distance.

Example:

• Instead of “I was walking into the room,”

• You write “I walk into the room and I feel…”
  

This increases emotional engagement, which is the engine of change in exposure therapy.

3. Focus on the thoughts and feelings you had during the event

You’re encouraged to include:

• What you feared

• What you believed was happening

• What you thought would happen next

• What the worst moment was

This isn’t a factual report—it’s an emotional one.

4. Include sensory details

Therapists often prompt you to write about:

• What you saw

• What you heard

• What you smelled

• Physical sensations in your body

These details help activate the memory fully.

5. Keep writing continuously

You’re told not to stop, edit, or analyze. If you get stuck, you write about being stuck until the flow returns.

The goal is immersion, not perfection.

6. Don’t worry about grammar, spelling, or structure

This is not a narrative exercise. It’s about emotional exposure, not literary quality.

7. After writing, briefly reflect on how it felt

Just a few sentences—no deep processing. The therapist doesn’t interpret or challenge anything you wrote.

*Why These Instructions Matter

They’re designed to:

• Reduce avoidance

• Activate the traumatic memory in a safe, controlled way

• Allow the brain to naturally process and integrate the experience

• Decrease distress over repeated sessions

The simplicity is intentional—it keeps the focus on exposure, not analysis.

SUMMARY: So here is why I choose WET as opposed to PE for some people.

1. It’s dramatically shorter and less demanding

• WET: 5 sessions, no homework

• PE: 8–15 sessions, 90 minutes each, plus intensive in‑vivo homework

Some clients simply won’t or can’t commit to PE’s workload. WET gives them a viable, evidence‑supported alternative.

2. Lower emotional burden

PE requires:

• Repeated imaginal exposure

• Listening to recordings of the trauma

• Real‑world exposure to avoided situations

For some people, that level of intensity feels overwhelming or unsafe.

WET still uses exposure, but:

• It’s contained to 30 minutes of writing

• There’s no audio recording

• There’s no in‑vivo homework

• The therapist’s role is lighter

This makes it easier for clients who fear being “flooded” or who have limited tolerance for prolonged emotional activation.

3. Much lower dropout rates

In head‑to‑head research, WET consistently shows better retention than PE. Why?

• Less time

• Less homework

• Less emotional strain

• Simpler structure

For clients who are ambivalent about trauma therapy, WET is often the more approachable doorway.

4. It works well even when clients have complex lives

People with:

• caregiving responsibilities

• shift work

• limited transportation

• chronic stress

• limited privacy at home

…often struggle with PE’s time and homework demands. WET’s minimal structure makes it more accessible.

5. It’s easier to deliver via telehealth

WET’s simplicity—brief sessions, no homework, no recordings—makes it especially telehealth‑friendly. PE can be done remotely, but it’s more logistically complex.

6. It’s ideal for clients who avoid talking about trauma

Some people:

• freeze when speaking aloud

• feel ashamed or embarrassed

• struggle to articulate verbally

• prefer writing as a mode of expression

WET leverages writing as the exposure medium, which can feel safer and more private.

7. It’s a great option for clients who want trauma treatment but fear “traditional” trauma therapy

Many clients say things like:

• “I don’t want to talk about it over and over.”

• “I don’t want to do homework.”

• “I don’t want to go to the place where it happened.”

WET gives them a structured, evidence‑based path that feels less intimidating.

The bottom line: PE is still the gold‑standard, comprehensive exposure therapy. But WET is often the better match for people who need something shorter, simpler, and less emotionally taxing—without sacrificing meaningful symptom improvement.

EMDR:
Clients who do WET do not need EMDR, and the two treatments are not typically combined—but some people may choose to do EMDR after WET if symptoms remain.

So if you’re not sure what approach is best for you, let’s discuss it.
