Sleep Disturbances and Behavioural Phenotypes in Children With Autism Spectrum Disorder: A Comparative Study With...

Area of Science:

• Neurodevelopmental Disorders
• Pediatric Sleep Medicine
• Behavioral Psychology

Background:

• Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social communication deficits and restricted, repetitive behaviors.
• Sleep disturbances are frequently reported in children and adolescents with ASD, impacting their daily functioning and overall well-being.
• Understanding the specific links between sleep problems and behavioral challenges in ASD is crucial for targeted interventions.

Purpose of the Study:

• To investigate the relationship between various sleep problems and specific behavioral difficulties in children and adolescents with autism spectrum disorder (ASD).
• To compare these relationships in ASD with those in typically developing children (TDC).

Main Methods:

• A comparative study involving 40 children/adolescents with ASD and 50 TDC, all with normal intellectual functioning.
• Utilized the Sleep Disturbance Scale for Children (SDSC), Conners' Parent Rating Scale-Revised Short (CPRS-RS), and Repetitive Behaviour Scale-Revised (RBS-R).

Main Results:

• Participants with ASD exhibited significantly higher scores on measures of inattention, hyperactivity, and various repetitive behaviors (stereotyped, self-injurious, compulsive, routine, sameness, restricted) compared to TDC.
• The ASD group also reported more difficulties initiating and maintaining sleep.
• Correlation and regression analyses revealed significant associations between specific repetitive behaviors (e.g., sameness, compulsive) and distinct sleep problems (e.g., timing, arousal/waking, breathing) in the ASD group.

Conclusions:

• Sameness behaviors, compulsive behaviors, and overall repetitive behaviors are significantly associated with several sleep problems in children and adolescents with ASD.
• These findings highlight robust links between specific sleep disturbances and particular behavioral difficulties within the ASD population.
• The study underscores the importance of addressing sleep issues to potentially mitigate behavioral challenges in individuals with ASD.
