Insights

A family-based intervention improved early attention-deficit/hyperactivity disorder (ADHD) symptoms in at-risk children. However, a later booster intervention did not enhance these preventive effects over five years.

Area of Science:

  • Developmental Psychology
  • Child Psychiatry
  • Preventive Interventions

Background:

  • Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder impacting children's academic and social functioning.
  • Early identification and intervention are crucial for mitigating the long-term effects of ADHD symptoms.
  • Family-based approaches show promise in addressing the complex needs of children at risk for ADHD.

Purpose of the Study:

  • To evaluate the efficacy of a family-based preventive intervention (SAFE Children) in altering the developmental trajectory of ADHD symptoms in first-grade children.
  • To assess the impact of a booster intervention in fourth grade on sustained preventive effects.
  • To identify distinct developmental pathways of ADHD symptoms in an inner-city population.

Main Methods:

  • A randomized controlled trial involving 424 families with children entering first grade.
  • Intervention group received the Schools and Families Educating Children (SAFE) Children program, combining family prevention and academic tutoring.
  • Growth mixture modeling was used to analyze longitudinal parent and teacher reports of ADHD symptoms over five years.

Main Results:

  • The initial SAFE Children intervention positively influenced developmental trajectories for impulsivity and hyperactivity.
  • This suggests potential for ADHD prevention in at-risk youth through early, comprehensive interventions.
  • A booster intervention in fourth grade did not yield additional benefits on ADHD symptom trajectories or indicators.

Conclusions:

  • Early family-based interventions can positively impact the developmental course of ADHD symptoms in young children.
  • The findings highlight the potential for preventive strategies in addressing ADHD in underserved populations.
  • Further research is needed to optimize the timing and components of booster interventions for sustained effects.

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.

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.

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;...

Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

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.
