An Exploratory Study Testing Environmental Wayfinding Aids as an Intervention for Children With Autism.

Researchers tested whether special visual aids (colored doors, shapes on floors, and signs) could help autistic children navigate unfamiliar places better. Nine children were split into two groups - one used regular directions, the other used the special visual aids. All children found their destination, but those using visual aids took more direct routes and remembered the path better. This suggests these aids might help autistic children become more independent when moving around unfamiliar buildings.

This exploratory randomized controlled trial investigated whether wayfinding aids (colored doors, floor shapes, and signage) could help children with autism spectrum disorder navigate unfamiliar environments independently. Nine participants aged 8-11 were randomly assigned to control or treatment groups in an empty school corridor. The control group received standard wayfinding instruction using existing environmental cues, while the treatment group used applied wayfinding aids. Both groups successfully reached their destination, but 100% of the treatment group found their way directly compared to 75% of the control group.

Treatment group participants found the environment more memorable. The study suggests wayfinding instruction could serve as an intervention, though further testing in diverse environments is needed.

Environmental wayfinding aids show promise for supporting independence in autistic children. Clinicians should consider visual navigation supports when working in complex environments like healthcare settings. Further research needed before implementation as standard practice.

Very small sample size (n=9), single test environment, exploratory design with methodological concerns including recruitment difficulties and random assignment issues. Limited generalizability to other environments or real-world settings.

This exploratory mixed methods experiment aimed to determine whether the application of wayfinding aids (colored doors, shapes on the floor, and signage) as an intervention could help children with autism spectrum disorder (ASD) find their way to a destination to promote independence. Several individuals with ASD have described the difficulties they experienced finding their way in the environment. This is especially relevant to complex environments like healthcare. Participants with ASD aged 8-11 (= 9) were randomly assigned to control or treatment groups.

The test location was an empty school corridor unfamiliar to participants. Each participant was shown the way to a destination using a script pointing out existing cues (control group) or applied wayfinding aids (treatment group). Participants were taken back to the start and then asked to lead the way to the destination. Afterward, they were interviewed about their experience.

Data collection included observation, behavioral mapping, and video recording. The variable of wayfinding scripts helped all participants find their way to the destination, but those in the treatment group found their way directly compared to 75% of the control group. Wayfinding aids made the environment more memorable to those in the treatment group. Some children were distracted by environmental stimuli, and some noticed surprising elements that helped them wayfind.

Study results suggest that wayfinding instruction could be used as an intervention in environments with and without the application of wayfinding aids. This needs further testing in other environments. Issues included recruitment and random assignment.
