Children (6-12 yrs; n = 30) who meet full DSM (Diagnostic and Statistical Manual) criteria18 for ASD and insomnia will be recruited from an existing clinical registry database. Eligibility criteria for initial recruitment will include IQ (intelligence quotient) of 75 or above (to ensure ability to participate in cognitive components of treatment), previous DSM diagnosis of ASD, and previous evaluation using gold standard diagnostic tools, including the Autism Diagnostic Observation Schedule (ADOS)27 and/or Autism Diagnostic Interview - Revised (ADI-R).28 The Thompson Center database currently includes 337 children with ASD ages 6-12 who have completed the ADOS and/or ADIR and have IQ>75. Following initial recruitment, eligibility for participation will include DSM diagnosis of insomnia. Insomnia will be diagnosed by study staff using gold standard diagnostic tools, a brief (10 min.) structured interview, Child Sleep Habits Questionnaire29, and sleep diaries.30 Child will report or parent will observe sleep latency (time to fall asleep) or wake during the night >30 minutes that is confirmed by baseline sleep diaries. Dr. Sahota will provide referrals for children with suspected sleep apnea. Additional criteria will include participation of the child's parent or legal guardian living in the same home, and parental ability to read and understand English at the 5th grade level. Given previous experience, size of the database and insomnia prevalence in ASD, the investigators expect no difficulty recruiting our target sample size.
