This study identified differential impairments underlying IGT performance in AN and BN. Findings suggest that impaired decision making in AN might involve impaired memory functions. Impaired decision making in BN might involve altered reward and punishment sensitivity.

Insomnia is common in autism and associated with challenging behavior and worse parent sleep. Cognitive behavioral treatment for childhood insomnia (CBT‐CI) is efficacious in typically developing children, but not yet tested in school‐aged children with autism. This single arm pilot tested 8‐session CBT‐CI in 17 children with autism and insomnia (M age = 8.76 years, SD = 1.99) and their parent(s) (M age = 39.50 years, SD = 4.83). Treatment integrity was assessed for each session [delivery (by therapist), receipt (participant understanding), and enactment (home practice)]. Children and parents wore actigraphs and completed electronic diaries for 2‐weeks to obtain objective and subjective sleep onset latency (SOL), total sleep/wake times (TST/TWT), and sleep efficiency (SE) at pre/post/1‐month follow‐up. Parents also completed the Aberrant Behavior Checklist [irritability, lethargy, stereotypy, hyperactivity, inappropriate speech (e.g., excessive/repetitive, loud self‐talk)] at pre/post/1‐month. Fifteen children completed all sessions. Average integrity scores were high [90%‐delivery/receipt, 87.5%‐enactment]. Parents found CBT‐CI helpful, age‐appropriate, and autism‐friendly. Paired samples t‐tests (family‐wise error controlled) found CBT‐CI improved child sleep (objective SOL‐18 min, TWT‐ 34 min, SE‐5%; subjective SOL‐29 min, TST‐63 min, TWT‐45 min, SE‐8%), and decreased irritability, lethargy, stereotypy, and hyperactivity. At 1‐month, objective TST improved, inappropriate speech decreased, but hyperactivity was no longer decreased. Other gains were maintained. Parent sleep (objective SOL‐12 min, TST‐35 min, TWT‐21 min, SE‐4%; subjective SOL‐11 min, TWT‐ 31min, SE‐11%) and fatigue also improved. At 1‐month, gains were maintained. This pilot shows CBT‐CI is a feasible treatment that holds promise for improving child and parent sleep and functioning and suggests a randomized controlled trial in school‐aged children with autism is worth conducting.

Cognitive behavioral treatment for childhood insomnia (CBT‐CI) has not been tested in school‐aged children with autism. This pilot study shows therapists, parents, and children were able to use CBT‐CI to improve child and parent sleep, child behavior, and parent fatigue. Parents found CBT‐CI helpful, age‐appropriate, and autism‐friendly. CBT‐CI holds promise for treating insomnia in school‐aged children with autism and deserves further testing.
