Sleep problems and their correlates and comorbid psychopathology of children with autism spectrum disorders

An investigation of anxiety in children and adolescents with autism spectrum disorder

“…Contrary to this finding, Park et al (2012) reported strong associations between the presence of sleep difficulties and internalising problems such as anxiety. This study found that children with ASD who presented with sleep problems were more likely to have internalising problems, including anxiety, than ASD children without sleep problems.…”

“…This study found that children with ASD who presented with sleep problems were more likely to have internalising problems, including anxiety, than ASD children without sleep problems. Park et al (2012) stated that these psychological problems, which are common in children with ASD, may exacerbate or be exacerbated by sleep difficulties.…”

Sleep Problems in Autism Spectrum Disorder: A Literature Review

“…Schreck et al (2004) Night-time fragmentation of sleep was significantly associated with total repetitive behavior as well as the individual scales of compulsive behaviors, need for sameness and restricted behaviors. Park et al (2012) found that children with ASD and sleep problems were more likely to have aggressive behaviors and externalizing problems compared to children with ASD without sleep problems. In support, Sikora et al (2012) found that children with ASD and sleep problems have more externalizing and internalizing behavior problems than those with ASD and no sleep problems.…”

“…Goldman et al (2011) found a smaller prevalence of sleep problems, where 33% of their sample were identified as poor sleepers. Park et al (2012) found that 47% of children with ASD had at least one sleep problem.…”

“…Good sleepers with ASD showed fewer affective problems than poor sleepers with ASD. Park et al (2012) examined the relationship between sleep problems and comorbid psychopathology in children with ASD and their unaffected siblings. Children with ASD who also had comorbid sleep problems were more likely to have withdrawal problems, somatizing Sleep problems in autism spectrum disorder problems, internalizing problems and overall total behavior problems than children with ASD who did not have sleep problems.…”
