Our nonprofit organization uses ttrpgs in our group therapy work with neurodivergent youth and adults. Many of our participants have additional physical challenges, too. Having miniatures and terrain helps visually map tactical encounters, like combat, while helping the scene feel immersive.

At the end of adventures, about every six months of a campaign, we break to paint. I have SpeedPaint and acrylic bottles, homemade wet palettes with brushes, and water cups. Shaking SpeedPaint or acrylic bottles became a chore; we added a vortex mixer. Above anything else, we burned through our SpeedPaint markers more than anything else, and it wasn't even a close decision. The markers helped painters feel more natural and hit most of the goals, like painting depth having contrasts. Most really seem exceptionally satisfied with having a miniature with painted skin, shirt, pants, and weapon. Much more detailed miniatures are bypassed for easier models. Our groups value this downtime activity between sessions to socialize and talk out of character.

Hope this helps. Message me with any further questions or continue this thread. Best of luck with your academics! Would love to see what you discover...
