Police Stops Among Adolescents With Intellectual and Developmental Disabilities: Implications for Traumatic Stress

The present study examines differences in police stops, features of those stops, and stress outcomes between youth with and without intellectual and developmental disabilities (IDD).

Data from Wave 6 (age 15) of the Future of Families and Child Wellbeing Study (FFCWS), a national sample of urban-born youth in the U.S., was analyzed in 2025 (n = 3,444). Logistic regression models first examined associations between IDD diagnosis and direct police stops. Negative binomial regressions and linear regressions were then conducted among the subsample of youth who reported a direct police stop (n = 918) to examine the associations between IDD diagnosis and officer intrusiveness, perceptions of procedural justice, emotional distress during the direct stop, and police-initiated post-traumatic stress (PI-PTSS).

Youth with IDD diagnoses did not have significantly greater odds of experiencing a direct police stop than youth without IDD. However, among youth with a direct police stop, youth with IDD diagnoses reported higher emotional distress during direct police stops and higher PI-PTSS than youth without IDD.

These findings indicate that direct police stops may have more detrimental effects on stress and mental health of youth with IDD compared to youth without IDD. Policy reform, officer training, and additional research are needed to safeguard the mental health and wellbeing of youth with IDD.
