Play Therapy With Adults

What actually happens when you use play materials with grown people in a therapy room

Most people assume play therapy is just for kids. They picture sand trays and coloring books and someone asking a teenager to draw their feelings. It looks silly until you've sat across from a 42-year-old man who hasn't spoken a full sentence in three sessions and then watches him build an entire city in the sand tray without saying a word. That's when it clicks. The play isn't decorative. It's the actual medium of communication. Play Therapy With Adults works because trauma and anxiety live in the body and in non-verbal circuits of the brain before they ever reach the part of your mind that can string words together. Talk therapy assumes the client can access verbal processing. That's a big assumption. A lot of people can't, not because they're stubborn, but because their nervous system has learned that putting experience into language is dangerous or pointless. Play bypasses that bottleneck. I've been doing this work for over a decade now and the thing nobody tells you upfront is that adults initially resist it harder than kids do. A kid picks up a figurine and goes. An adult stares at the tray like it's contaminated. You have to normalize it fast. I usually say something like "We're just going to see what shows up" and hand them the tray. That's it. No explanation. No "research shows." Just hand it over and wait.

The mechanics behind why it works for grown-ups

The core mechanism is symbolic externalization. When someone arranges objects in a sand tray or manipulates figures in a dollhouse scene, they're taking internal chaos and giving it physical form. That act alone reduces amygdala activation. The prefrontal cortex gets involved again. This is why a client who has been stuck describing the same stressful event in identical words for six weeks will suddenly say something entirely new after two sessions of sand tray work. They weren't stuck because they lacked insight. They were stuck because they couldn't access the material until it was externalized. There's also the displacement effect to consider. Adults often feel safer exploring painful content through proxies. A woman building a scene where a figure is trapped in a locked room is rarely going to say "I feel trapped in my marriage." But she will say "the person in the red dress doesn't seem to be able to leave." From there you can ask her to describe what the locked room looks like and the conversation opens naturally. No confrontation needed. I worked with a client last year who had severe panic disorder and had tried CBT three times without success. The problem wasn't that the techniques were wrong. It was that every time we talked about the panic, her body re-engaged the threat response and she'd spend the next ten minutes dissociating. We switched to drawing and collage instead of talking. She cut out images of storms and locked doors and tangled strings and arranged them on a large sheet. In that format, she could look at her anxiety from a distance. We spent three sessions just arranging and rearranging images before she ever used the word "panic." By session four she described the feeling directly and we could actually work with it. The total process took about eight sessions instead of the eighteen we'd been attempting with pure talk therapy.

Setting up a session that doesn't feel like a gimmick

You need the right materials and the right framing. The materials list is shorter than most people expect. A standard sand tray setup includes a wooden tray approximately 57 by 72 centimeters filled with damp sand, a collection of small figurines representing people, animals, buildings, trees, vehicles, and abstract symbols, and a storage cabinet so nothing gets lost between sessions. For non-tray work you need journals, colored pencils, clay, stamps, and a box of miscellaneous objects like shells or stones or small toys. That's it. You don't need anything fancy. The framing matters more than the supplies. I tell clients something like "Some people find it helpful to work with objects when words aren't enough. We can try that if you want. No pressure." That's the entire pitch. If they say no, we move on. Pushing it creates resistance and the whole approach falls apart. About 60 percent of adults I offer it to will agree at least once. Of those, roughly 40 percent come back and ask to use it again in a future session. Session structure is straightforward. Opening check-in takes about five minutes. Then you introduce the medium if it's the first time. For sand tray work I say "Take your time. Pick whatever feels drawn to you." Clients usually start within two minutes. The creative phase runs 15 to 25 minutes depending on the person. Closing integration is where most people mess up. You don't just wrap up and say "anything else?" You guide them through a brief processing period. I typically ask "What do you notice now?" or "Is there anything in the scene you want to change before we finish?" Sometimes they change nothing and that's the point. Sometimes they move one figure and that movement tells you everything you need to know about their internal state.

Documentation is another area that trips people up. Photograph the tray scene before dismantling it. Note the arrangement, any changes made during the session, and your clinical impressions. The photo is crucial because the scene holds information that degrades as the client leaves the room. Two weeks later they'll remember pieces but not the spatial relationships. Your photo preserves that data.

Where this approach actually fails and what to do instead

It doesn't work for everyone and you should know that going in. Clients with active psychosis sometimes experience the play materials as overwhelming or confounding rather than helpful. A paranoid client might interpret a figurine as a surveillance device. Someone in a manic episode might fill the tray frantically without any reflective pause and then feel dysregulated afterward. In those cases standard talk therapy or medication management takes priority and play-based methods should be set aside entirely. Another limitation is time. Play therapy with adults usually requires slightly longer sessions than pure conversation-based work. The processing phase adds 10 to 15 minutes. If you're working in a system that bills strictly by 50-minute slots and you're already running behind, this adds friction. I've seen therapists skip the integration phase because they're behind schedule. Don't do that. Skipping integration turns the session into a recreational activity with no therapeutic anchor and the client walks out having played without having processed anything. For clients who are highly intellectualized and resist anything that feels childlike, you can adapt the approach. Instead of sand tray you can offer structured drawing exercises or guided visualization with sketching. One of my clients, a professor who called sand trays "pretend stuff," responded well to a method where he drew abstract representations of his anxiety as geometric shapes and then modified them over successive sessions. The principle was identical but the delivery matched his comfort level. The outcome was the same: reduced avoidance and increased emotional access.

The evidence base for play therapy with adults is growing but it's still smaller than the literature for child-focused work. Studies published between 2018 and 2024 show meaningful reductions in anxiety and PTSD symptoms across multiple trials, but sample sizes tend to be modest. What the research doesn't fully capture is the clinical nuance that comes from actually doing this work. Books like Adult Sandplay Therapy by Carol Franklin and Play Therapy with Adults by Schaverien provide the strongest theoretical foundations currently available. If you're looking to train, the Association for Play Therapy offers workshops specifically on adult applications. The bottom line is that play therapy with adults is not a backup option for people who "couldn't do talk therapy." It's a first-line intervention for a significant subset of clients who process information non-verbally. Trauma, dissociation, alexithymia, and chronic avoidance all respond differently to symbolic work than they do to direct verbal processing. The method is simple on the surface but the clinical judgment required to use it well develops over years of practice. Don't expect to read a manual and be proficient. Expect to sit with clients, watch what they do with the materials, and learn from what they show you rather than what they tell you.
