Sleep problems and sensory features in children with low-average cognitive abilities and autism spectrum disorder.

This study looked at sleep problems in autistic children and how they might relate to sensory issues and thinking abilities. The researchers found that autistic children with lower cognitive abilities had worse sleep when they also had more sensory difficulties. However, this connection wasn't seen in autistic children with higher cognitive abilities. This suggests that a child's thinking skills might affect how sensory issues impact their sleep.

This study investigated the relationship between sleep disturbances, sensory features, and cognitive abilities in children with autism spectrum disorder (ASD). Using standardized questionnaires completed by caregivers, researchers examined sleep quality, sensory processing, and cognitive skills in children with ASD. The key finding was that children with below-average cognitive scores showed a clear association between higher sensory processing difficulties and poorer sleep quality, while this pattern was not observed in children with above-average cognitive abilities. The findings suggest that cognitive ability may moderate the relationship between sensory features and sleep problems in autism, potentially informing targeted support strategies for different cognitive subgroups within the autism spectrum.

Results suggest sleep interventions for autistic children should consider both cognitive abilities and sensory processing patterns. Children with lower cognitive abilities and significant sensory issues may require more intensive sensory-focused sleep support strategies compared to those with higher cognitive abilities.

Sample size not reported, limiting assessment of study power. Cross-sectional design prevents determination of causal relationships. Reliance on caregiver reports may introduce bias. Study population appears limited to Japanese children, potentially affecting generalizability to other populations.

Children with Autism Spectrum Disorder (ASD) often have more sleep disturbances than typically developing children. These sleep disturbances have been suggested to be associated with atypical sensory features in children with ASD. Sleep habits have also been linked to intelligence and cognitive function in children. However, it remains unclear whether sleep disturbances in children with ASD are related to intelligence or sensory features.

This study examined whether sleep disturbances in children can be explained by the presence or absence of ASD characteristics, sensory features, and cognitive skills. Sleep disturbances and atypical sensory features were determined using the Japanese Sleep Questionnaire for Preschoolers and the Caregiver Sensory Profile, as reported by their caregivers. Cognitive skills were assessed using the Japanese translation of the Kaufman Assessment Battery for Children. Consequently, children with below-average cognitive scores demonstrated that higher sensory scores were associated with poorer sleep quality; children with above-average cognitive scores showed no such patterns.

These findings may aid in the development of support for sleep disturbances in various subtypes of ASD.
