Behavioural and emotional problems in children with intellectual disability attending special schools in Cape Town, South Africa

A sample of 355 children with intellectual disability (ID) attending special schools in Cape Town, South Africa, were assessed on the Developmental Behavioural Checklist - Teacher Version (DBC-T). A prevalence rate of 31% for psychopathology was found. Boys manifested more behaviour problems than girls, especially in relation to disruptive, self-absorbed and antisocial behaviours. Children with severe and profound levels of ID showed more behavioural difficulties than those in the mild and moderate categories. Specific behaviour problems were self-absorbed and autistic behaviours in children with profound ID, communication problems and anxiety in those with severe ID and antisocial behaviour in children with mild ID. Epilepsy, but not cerebral palsy was associated with higher total behaviour scores. Ambulant children were more disruptive and antisocial, while non-ambulant children were more anxious. Non-verbal children had higher scores on all of the subscales except for disruptive behaviour.
