Insights

Children with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) experience frequent sleep problems. These issues are linked to sleep hygiene and chronotype, with specific differences between ADHD, ASD, and typically developing children.

Area of Science:

  • Pediatric Sleep Medicine
  • Neurodevelopmental Disorders
  • Child Psychology

Background:

  • Sleep problems are common in children with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD).
  • Understanding the underlying mechanisms of sleep disturbances is crucial for developing effective interventions.
  • This study investigates factors influencing sleep in children with ADHD, ASD, and typical development (TD).

Purpose of the Study:

  • To examine the associations between sleep problems and sleep patterns with sleep hygiene, electronic media access, chronotype, and anxiety/depression in children with ADHD, ASD, and TD.
  • To identify differences in these associations across the three groups.
  • To inform clinical strategies for managing sleep issues in pediatric populations.

Main Methods:

  • Parental questionnaires were used to collect data from children aged 6-12 years with ADHD, ASD, or TD.
  • Analyses included ANOVA and linear regression, adjusted for age and sex.
  • Key variables assessed were sleep problems, sleep duration, sleep hygiene, electronic media use, chronotype, and anxiety/depression.

Main Results:

  • Children with ADHD and ASD reported significantly more sleep problems and shorter sleep duration compared to TD children.
  • Worse sleep hygiene was associated with more sleep problems in ASD and TD groups, but not significantly in the ADHD group.
  • Evening chronotype was linked to sleep problems in ADHD and TD groups, while electronic media access was associated with sleep problems only in TD children.
  • Anxiety and depression were associated with sleep problems in ADHD and TD groups, but did not moderate other factors.

Conclusions:

  • Sleep problems are highly prevalent in both ADHD and ASD, with distinct contributing factors.
  • In ASD, sleep problems are linked to inadequate sleep hygiene; in ADHD, they are associated with evening chronotype.
  • In typically developing children, both sleep hygiene and chronotype play a role in sleep problems.
  • These findings highlight the need for tailored interventions for sleep disturbances in neurodevelopmental disorders.

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....

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.

Insomnia01:27

Insomnia

Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

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.

Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...
