Sleep and Challenging Behaviors in the Context of Intensive Behavioral Intervention for Children with Autism

Area of Science:

• Neurodevelopmental disorders
• Behavioral science
• Sleep medicine

Background:

• Autism spectrum disorder (ASD) is a neurodevelopmental condition often associated with sleep disturbances.
• Challenging behaviors are common in children with ASD and can impact treatment efficacy.
• Intensive behavioral intervention (IBI) is a common treatment approach for ASD.

Purpose of the Study:

• To investigate the relationship between average sleep quality and night-to-night sleep variability with challenging behaviors in children with ASD undergoing IBI.
• To determine if sleep patterns or fluctuations are more strongly associated with behavioral outcomes.

Main Methods:

• Sleep patterns of 39 children with ASD were objectively measured using actigraphy over five consecutive nights.
• Clinician-reported data on challenging behaviors were collected concurrently.
• Statistical analyses examined associations between sleep parameters (average and variability) and specific challenging behaviors.

Main Results:

• On average, poorer sleep was significantly associated with increased rates of repetitive behaviors, negative affect, and overall challenging behaviors.
• Night-to-night fluctuations in sleep did not show a significant association with challenging behaviors.
• Average sleep patterns emerged as a more critical factor than sleep variability.

Conclusions:

• Average sleep quality, rather than nightly fluctuations, is importantly associated with challenging behaviors in children with ASD receiving IBI.
• Interventions targeting overall sleep improvement may positively impact challenging behaviors and developmental progress in this population.
• Findings underscore the significance of addressing sleep as part of comprehensive IBI for children with ASD.
