Clinical and Demographic Correlates of Insomnia Symptoms in Children with Autism Spectrum Disorder
摘要
To examine demographic and clinical characteristics of sleep problems in autistic children.
MethodsParents of 1,185 children (mean age 9.8 ± 2.0, range 3–12 years; 80.3% boys) were recruited from the Simons Powering Autism Research (SPARK) database for the online survey. Caregivers completed the 21-item, unidimensional Pediatric Autism Insomnia Rating Scale (PAIRS), the Aberrant Behavior Checklist (ABC), the Social Communication Questionnaire (SCQ), a demographic form and a question on chronotype. We set a PAIRS score of ≥ 33 (75th percentile in this sample) to define insomnia as a clinical concern.
ResultsThe PAIRS mean was 21.8 ± 15 (range 0 to 63); 304 children were rated ≥ 33. PAIRS mean scores were higher in girls than boys (23.5 ± 14.7 vs. 21.3 ± 15.0, p = 0.044), in children ages 3–7 than those ages 8–12, (23.8 ± 15.4 vs. 21.2 ± 14.8, p = 0.022), in non-verbal children than verbal children (28.5 ± 14.7 vs. 20.5 ± 14.7, p < 0.001), and in children with evening chronotype than those with morning or neither preference (23.3 ± 14.8 vs. 20.8 ± 19.7, p < 0.01). Children with parent-reported below average IQ and children of parents without a college degree also had higher PAIRS scores. Those with ≥ 33 on PAIRS had higher scores on all ABC subscales. Unadjusted and adjusted logistic regression modeling showed that higher ABC Hyperactivity, ABC Social Withdrawal, and ABC Irritability scores, parent-reported below average IQ, and an evening chronotype significantly increased the odds of being rated ≥ 33 on the PAIRS.
ConclusionPAIRS can be used for insomnia screening, as an outcome measure in clinical trials and in clinical care for autistic children.
