Sleep in Children With Autism and Intellectual Disability

Purposes: Establish proof-of-concept for home polysomnography in the assessment of sleep disorders among prepubertal school children with autism and intellectual disabilities combined; To explore the diagnostic yield of polysomnography for these individuals; To examine the feasibility and treatment effect of Applied Behavior Analysis (ABA) for insomnia, focusing on sleep maintenance difficulties, in these children.

Method: Single-case experimental design with multiple baselines and with multiple participants, with a focus on feasibility. N=15 prepubertal children, aged 6-12 years, with autism and intellectual disabilities combined, and difficulties in maintaining nighttime sleep. Assessment with home polysomnography + actigraphy. Intervention with ABA, including functional analysis, measurable goals, and behavior modification based on the functional analysis. Outcome measures from actigraphy and sleep diary with multiple data points at baseline and after treatment. Feasibility is examined as adherence to assessment and treatment, as well as in a qualitative study of parental experiences.
