Insights
Children with Autism Spectrum Disorder (ASD) frequently experience sleep disorders, which are linked to increased behavioral and emotional problems. Early screening and intervention for sleep issues in ASD are recommended for better clinical practice.
Area of Science:
- Pediatric Neurology
- Developmental Psychology
- Sleep Medicine
Background:
- Sleep disorders are prevalent in children with Autism Spectrum Disorder (ASD) but often underdiagnosed.
- Clinical practice frequently misdiagnoses or undertreats sleep problems in this population.
Purpose of the Study:
- Identify sleep disorders in preschool children with ASD.
- Examine the relationship between sleep disorders and core autism symptoms, developmental level, and psychiatric comorbidities.
Main Methods:
- Recruited 163 preschool children diagnosed with ASD.
- Assessed sleep using the Children's Sleep Habits Questionnaire (CSHQ).
- Evaluated cognitive abilities, repetitive behaviors (Repetitive Behavior Scale-Revised), and emotional-behavioral problems (Child Behavior Checklist -CBCL 1½-5).
Main Results:
- Children with ASD and sleep disorders scored higher on CSHQ and CBCL across all domains.
- Severe sleep disorders correlated with increased internalizing, externalizing, and total problems on CBCL.
- Anxiety symptoms mediate the association between sleep disorders and restricted and repetitive behaviors (RRBs).
Conclusions:
- Sleep problems are significantly associated with broader challenges in children with ASD.
- Routine screening and early intervention for sleep issues are crucial in ASD clinical practice.
Background:
Sleep disorders are one of the most common problems in children with Autism Spectrum Disorder (ASD). However, they often tend to be underdiagnosed and incorrectly treated in clinical practice. This study aims to identify sleep disorders in preschool children with ASD and to explore their relationship with the core symptoms of autism, the child's developmental and cognitive level as well as the psychiatric comorbidities.
Methods:
We recruited 163 preschool children with a diagnosis of ASD. The Children's Sleep Habits Questionnaire (CSHQ) assessed sleep conditions. Multiple standardized tests were used to evaluate intellectual abilities, the presence of repetitive behaviors (through the Repetitive Behavior Scale-Revised), as well as the emotional-behavioral problems and the psychiatric comorbidities (through the Child Behavior Checklist -CBCL 11/2-5).
Results:
The results showed that poor disorders had consistently higher scores in all areas assessed by the CSHQ and on the CBCL across all domains. The correlational analysis showed that severe sleep disorders were associated with higher scores in internalizing, externalizing, and total problems at the CBCL syndromic scales, and in all DSM-oriented CBCL subscales. Moreover, we found that the association between sleep disorders and restricted and repetitive behaviors (RRBs) is explained by the anxiety-related symptoms.
Conclusion:
Based on these findings, the study recommends that screening for sleep problems followed by early intervention should constitute a routine part of clinical practice for children with ASD.
