Social communication deficits in disruptive primary-school children.

BACKGROUND Parent and teacher data, from questionnaire surveys, suggest that school-identified disruptive children often have pragmatic language deficits of an autistic type. AIMS This replication study aimed to confirm earlier findings, using individual clinical assessment to investigate traits of autism-spectrum disorder in disruptive children. METHOD Persistently disruptive children (n = 26) and a comparison group (n = 22) were recruited from primary schools in a deprived inner-city area. Measures included standardised autism diagnostic interviews (with parents) and tests of IQ, social cognition, theory of mind and attention (with children). RESULTS The disruptive children possessed poorer pragmatic language skills (P<0.0001) and mentalising abilities (P<0.05) than comparisons. Nine disruptive children (35%) met ICD-10 criteria for atypical autism or Asperger syndrome. CONCLUSIONS Many persistently disruptive children have undetected disorders of social communication, which are of potential aetiological significance.
