Insights

Sleep disturbance is common in children with autism spectrum disorder (ASD). Over one year, sleep issues decreased in ASD children, correlating with better social skills and predicting reduced anxiety.

Area of Science:

  • Neurodevelopmental disorders
  • Pediatric sleep medicine
  • Autism spectrum disorder research

Background:

  • Sleep disturbance is a prevalent issue in children with autism spectrum disorder (ASD).
  • Longitudinal patterns and changes in sleep disturbance over time within ASD populations are not well understood.
  • Understanding these changes is crucial for identifying effective interventions and support.

Purpose of the Study:

  • To investigate the longitudinal changes in sleep disturbance in children with ASD compared to typically developing (TYP) children.
  • To examine the relationship between changes in sleep disturbance and problem behaviors, including social ability and anxiety.
  • To define the trajectory of sleep disturbance in ASD over a one-year period.

Main Methods:

  • A cohort of 84 gender-matched children (aged 7-12 at baseline), including 46 with ASD and 38 TYP children, was studied.
  • Parental reports using standardized scales were collected at baseline and after one year to assess sleep disturbance and associated behaviors.
  • Statistical analyses were performed to compare groups and examine changes over time and correlations.

Main Results:

  • Children with ASD exhibited significantly higher levels of sleep disturbance compared to TYP children at baseline.
  • Sleep disturbance notably decreased over the one-year study period in the ASD group, whereas it remained stable in the TYP group.
  • A reduction in sleep disturbance was associated with improvements in social abilities among children with ASD.
  • Baseline sleep disturbance emerged as a significant predictor of later anxiety symptoms in the ASD cohort.

Conclusions:

  • Sleep disturbance follows distinct longitudinal trajectories in children with autism spectrum disorder.
  • Interventions aimed at reducing sleep disturbance in ASD may positively impact social functioning and anxiety levels.
  • Further research is warranted to explore the mechanisms underlying these sleep changes and their long-term implications for individuals with ASD.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.
