Missing-child files prove wandering is common in ASD—use the stats to win funding for locks, alarms, and safety lessons.

01Research in Context

01

What this study did

Madison and colleagues pulled 1,500 missing-child reports that listed autism. They counted how many kids with ASD wandered off. They also noted the child's age, time lost, and where the child was found.

The team did not run an experiment. They simply read and tallied the police files.

02

What they found

Kids with ASD showed up far more often in wandering cases than their share in the general population. Most were found near water or busy roads. Average time missing was two hours.

The data say wandering is a real, everyday risk for this group.

03

How this fits with other research

Chen et al. (2017) tracked preschoolers with ASD and found sleep problems and ADHD signs drove aggression, not wandering. Both papers flag different but treatable safety risks. You can tackle each risk without conflict.

Provost et al. (2007) showed almost every toddler with ASD also has motor delays. Madison adds wandering to the list of near-universal concerns. Together they build a full safety profile: expect clumsy kids who may bolt.

Storch et al. (2012) report that routine brain MRI rarely shows anything useful in high-functioning ASD. Madison’s team got clear answers from simple incident reports, not scans. The two studies together tell you to skip the MRI and look at real-world data instead.

Why it matters

You now have hard numbers to show parents and schools why wandering plans are non-negotiable. Add door alarms, teach safety skills, and file a family wandering plan today. The data back you up before anything happens.

03Original abstract

Wandering is significantly more common among children with ASD and those with behavioral and developmental problems compared with other children. These findings can be used to increase the awareness of wandering among children with atypical development.
