Child Maltreatment Among Children With Intellectual Disability in the Canadian Incidence Study.

Dion et al. (2018) looked at every child in Canada who entered the child-protection system. They asked: how many have intellectual disability (ID)?

The team pulled data from the Canadian Incidence Study. They compared abuse type, severity, and services offered for kids with and without ID.

One in every ten proven abuse cases involved a child with ID. These kids suffered worse injuries and had more daily-life problems.

They were also sent to long-term services far more often than other children.

Van Hanegem et al. (2014) extends the story. They tracked teen offenders and found 70% of those with ID had prior abuse records. Only 42% of non-disabled offenders had the same history. Abuse in early life links more strongly to later sexual offenses for youth with ID.

Granillo et al. (2022) shows why early ID flags matter. Routine clinic notes miss 60% of kids who actually have ID. If clinics overlook ID, child-protection teams will too.

Mansell et al. (2002) adds a service-gap warning: two-thirds of youth with ID and mental-health needs get zero specialist care. Jacinthe’s finding that these kids are referred more often still leaves room for under-treatment once they are in the door.

You can spot ID early during intake. Ask about school placement, daily living skills, and previous diagnoses. One clear question up front can push a case toward the right services and keep a child from cycling back with new injuries.
