Objective: This study examined the persistence of sleep problems in preschool children with autism and two matched comparison groups: children with developmental delay without autism and typically developing children. Sleep problems were defined subjectively by parent report, by the Children's Sleep Habits Questionnaire (CSHQ), and objectively by quantitative Research Diagnostic Criteria (RDC) derived from actigraphic recordings.
Method: Children were studied on three occasions, each separated by a 3-month interval.
