Insights
The Pediatric Autism Insomnia Rating Scale effectively measures sleep problems in autistic children. This new scale is brief, valid, and provides reliable scores for assessing insomnia in children with autism spectrum disorder.
Area of Science:
- Pediatric sleep medicine
- Autism spectrum disorder research
- Psychometric scale development
Background:
- Insomnia is a prevalent issue in children with autism spectrum disorder (ASD).
- Previous research focused on parent focus groups to develop a rating scale for pediatric autism insomnia.
- A validated, reliable measure is needed to assess insomnia in this population.
Purpose of the Study:
- To report on the completion and validation of the Pediatric Autism Insomnia Rating Scale (PAIRS).
- To establish the psychometric properties of the PAIRS for use in children with ASD.
- To confirm PAIRS measures insomnia symptoms specifically, differentiating them from other ASD-related behaviors.
Main Methods:
- Data collected from 1185 children with ASD via the Simons Foundation registry.
- Statistical evaluation including factor analysis to test the new measure.
- Video conference assessments with a separate sample of 134 autistic children to confirm validity.
Main Results:
- The PAIRS demonstrated clear measurement of insomnia symptoms in children with ASD.
- The scale effectively distinguished insomnia from hyperactivity, repetitive behaviors, and anxiety.
- Total scores on the PAIRS showed stability over brief repeated assessments, indicating reliability.
Conclusions:
- The Pediatric Autism Insomnia Rating Scale is a brief, valid, and reliable measure for assessing insomnia in children with ASD.
- PAIRS provides dependable scores crucial for outcome measurement in clinical trials and practice.
- This scale offers a valuable tool for clinicians and researchers addressing sleep disturbances in autistic children.
Lay Abstract:
Insomnia, trouble falling asleep or staying asleep, is common in autistic children. In a previous report, we described the results of focus groups with parents of autistic children toward the development of the Pediatric Autism Insomnia Rating Scale. In this article, we report on the steps taken to complete the Pediatric Autism Insomnia Rating Scale. With help from the Simons Foundation registry, we collected information from parents on 1185 children with autism spectrum disorder to test the new measure. These results were evaluated using standard statistical methods such as factor analysis. To confirm the validity of the new measure, we enrolled a separate sample of 134 autistic children for a detailed assessment by video conference. This step showed that the Pediatric Autism Insomnia Rating Scale is clearly measuring symptoms of insomnia in children with autism spectrum disorder and not related problems such as hyperactivity, repetitive behavior, or anxiety. We also showed that the total score on the Pediatric Autism Insomnia Rating Scale is stable when repeated over a brief period of time. This is important because a measure that is not stable over a brief period of time would not be suitable as an outcome measure. In summary, the Pediatric Autism Insomnia Rating Scale is a brief and valid measure of insomnia in children with autism spectrum disorder that provides reliable scores.
