Objective To identify clinical features that could distinguish children presenting with autistic-like features and a history of severe early maltreatment from children with idiopathic autism spectrum disorders (ASDs).
Design Matched-comparison study.
Setting Great Ormond Street Hospital, UK.
Participants 46 children with a history of early maltreatment, mean (SD) age 10.6 (3.3) years and 47 children with an ASD, mean (SD) age 10.4 (2.9) years.
Main outcome measures A range of standardised interview and observational measures that are designed to quantify autistic traits. Caregiver and teacher reports were obtained on broader aspects of behavioural and emotional adjustment.
Results Both groups had normal range IQ and were predominantly male. On the basis of autistic traits alone, caregiver interview and structured observation concurred that over 60% of the formerly maltreated children met criteria for an ASD. Autistic symptom profiles were very similar in both groups, although children with idiopathic ASD had significantly more marked repetitive and stereotyped behaviours. Teacher and caregiver reports indicated that children from both groups had an increased and broadly similar prevalence of emotional and behavioural disorders.
Conclusion Children presenting with a history of early maltreatment, who show autistic traits of behaviour, have a high risk of meeting diagnostic criteria for ASD. Their symptom profiles are virtually indistinguishable from children with idiopathic autism.
