Emotional and behavioural problems in children and young people with autism spectrum disorder in specialist autism schools

We investigated emotional and behavioural problems in a sample (N = 615) of children and young people with autism spectrum disorders (ASD), most of whom also had intellectual disability (ID), attending specialist autism schools. High rates of parent- and teacher-reported problems were recorded. Teacher-reported levels of hyperactivity were higher in younger children. Teacher- but not parent-reported levels of conduct problems and hyperactivity were highest in children without phrase speech. Greater use of mental health services was associated with higher levels of emotional and behavioural problems, but only a minority of participants had accessed mental health services in the previous 6 months.
