Expert panel to identify applications of virtual reality (VR) in cognitive behavioral therapy for alcohol use disorder: A Delphi study
Through a Delphi study with ten experts, this paper establishes a consensus-based blueprint for integrating virtual reality into cognitive behavioral therapy for alcohol use disorder, identifying key applications like practicing high-risk situations and outlining implementation barriers such as cost and therapist training.

Imagine you are trying to learn how to swim. You could sit in a classroom and listen to a teacher describe the perfect stroke, or you could read a manual about water safety. That's how most people learn to handle difficult situations in life right now: through talking and writing. But what if you could jump into a pool that felt exactly like the real ocean, complete with waves and currents, but without the risk of drowning? That is the promise of a technology called Virtual Reality (VR). It's a digital world you can step into, where your head movements control what you see and hear, making your brain think you are actually there.
This idea is especially exciting for helping people with Alcohol Use Disorder (AUD), a condition where drinking becomes hard to control. A common way to treat this is Cognitive Behavioral Therapy (CBT). Think of CBT as a training manual for the brain that helps people spot the "traps" that lead to drinking (like a stressful party or seeing a specific friend) and practice new ways to react, like saying "no" firmly or finding a different activity. The problem is, practicing these skills in a quiet office often feels different from the messy, loud reality of the real world. Scientists wondered: Could VR act like that perfect practice pool? Could it let people rehearse saying "no" to a drink in a fake bar, or practice staying calm in a fake stressful situation, so they are ready for the real thing?
A team of researchers decided to find out by asking the experts. They didn't just guess; they gathered a group of ten top specialists who know everything about treating alcohol problems with CBT. They used a special method called the "Delphi study," which is like a high-stakes game of "consensus." Imagine a group of master chefs trying to agree on the perfect recipe. They don't just shout out ideas; they write them down, rate them, see what the others think, and then rate them again until everyone agrees on the best ingredients and steps. In this case, the "ingredients" were ideas about how to use VR, and the "recipe" was a guide for therapists.
The experts started by brainstorming 89 different ways VR could be used. They then rated each idea on a scale of 1 to 5, asking things like, "How helpful would this be?" or "How important is this?" After four rounds of rating and discussing, the group reached a huge agreement on 84 of those 89 ideas (that's 94%!).
Here is what the experts agreed is the "perfect recipe" for using VR in this treatment:
The Best "Practice Drills"
The experts were most excited about using VR to practice high-risk situations. They agreed that VR is a fantastic tool for:
- Practicing saying "no": Rehearsing how to refuse a drink when someone offers one.
- Learning to be assertive: Practicing how to stand up for yourself without getting angry.
- Spotting triggers: Learning to recognize the specific people, places, or feelings that make someone want to drink.
- Simulating consequences: Seeing how a small, seemingly harmless decision (like going to a party) can lead to a relapse later.
They also agreed that therapists should be right there, coaching the patient in real-time while they are in the virtual world. It's like having a swimming coach in the pool with you, not just watching from the deck.
The "Swimming Pool" Settings
The experts said VR works best in social situations (like a house party or a restaurant) and stressful scenarios. They also agreed that therapists need to be able to customize the experience. Imagine a video game where you can adjust the difficulty; the experts wanted therapists to be able to change how loud the party is, how many people are there, or how strong the "pressure" to drink feels. They even agreed that adding a little bit of "unpredictability"—like a sudden loud noise or an unexpected guest—would make the practice feel more real and valuable.
When and Where to Dive In
The group agreed that VR fits into the middle of a therapy session, not necessarily at the very beginning or end. They also agreed that it can be used in almost any setting: whether the patient is at home (outpatient), in a hospital (inpatient), or living in a recovery center (residential). However, they noted that outpatient settings might be the most comfortable place to start, as patients there are often further along in their recovery.
The "Boring" Stuff They Said to Skip
The experts were very clear about what VR is not good for. They ruled out using it just to show people how bad drinking is (like a scary video of a hangover) or to help people track how much they drink. They felt that for those tasks, talking or writing is just as good, and VR doesn't add anything special. They also didn't agree that VR is the best way to help people find new, sober hobbies, though that idea was a bit controversial.
The Hurdles to Jumping In
Even though the experts loved the idea, they were realistic about the obstacles. The biggest barriers aren't the patients; the experts said patients are usually excited to try VR. The real trouble comes from the therapists. The main worries were:
- Tech fear: Therapists might be scared they aren't good with computers or headsets.
- Time: It takes time to learn how to use the tech.
- Money and Support: It costs money to buy the gear, and if the headset breaks or the internet cuts out, therapists need someone to fix it quickly.
- The "Luxury" Trap: If therapists think VR is just a fancy toy rather than a serious medical tool, they won't use it.
The paper concludes that while we have a great blueprint for how to use VR, we still need to test it in real life to see if it actually helps people drink less in the long run. The experts have drawn the map, but the journey to prove it works is just beginning.
