This study aimed to describe police interactions, satisfaction with police engagement, as well as examine correlates of police involvement among 284 adolescents and adults with autism spectrum disorder (ASD) followed over a 12- to 18-month period. Approximately 16% of individuals were reported to have some form of police involvement during the study period. Aggressive behaviors were the primary concern necessitating police involvement. Individuals with police involvement were more likely to be older, have a history of aggression, live outside the family home, and have parents with higher rates of caregiver strain and financial difficulty at baseline. Most parents reported being satisfied to very satisfied with their children’s police encounters. Areas for future research are discussed in relation to prevention planning.
