Prevalence and Correlates of Poor Safety Awareness and Accidental Injury in ASD, ADHD, ASD + ADHD, and Neurotypical Youth Samples

The purpose of the present study is to compare risk and predictors of poor safety awareness and accidental injuries in ASD, ADHD, and neurotypical samples. Neurodivergent groups (ADHD-I n = 309; ADHD-C n = 747; ASD-only n = 328; ASD + ADHD n = 1,108) were 2–17 years old. The neurotypical group (n = 186) was 6–12 years of age. Maternal ratings on the Pediatric Behavior Scale examined safety awareness, accidental injury, and psychological problems. Children with ASD + ADHD had significantly poorer safety awareness and accidental injury ratings than all other groups. Predictors of poor safety awareness in the total ASD and/or ADHD sample were: impulsivity, younger age, lower IQ, and hyperactivity. Predictors of accidental injuries were: incoordination, hyperactivity, and conduct problems. Clinicians working with children who have ASD and ADHD are encouraged to screen for poor safety awareness, discuss child safety measures, and provide evidence-based intervention to improve safety awareness and mitigate the risk of injury.
