Specific language impairments and behavioural problems.

The behavioural functioning of 56 children with a specific language impairment (SLI), aged 8, 10, and 12 years, was examined by using the Child Behaviour Checklist. Parents as well as teachers filled in the questionnaire. The data shows that 48% of the children with SLI were considered to have behavioural problems either at home or in school. The problems differ significantly from the norm group on internalizing behaviour and total behaviour. The children do not demonstrate more externalizing behaviour than children in the norm group. It is hypothesized that the absence of aggressive behaviour might be a characteristic of children with SLI.
