The relationship between executive function abilities, adaptive behaviour, and academic achievement in children with...

Area of Science:

• Neuroscience
• Developmental Psychology
• Child Psychiatry

Background:

• Executive function capacities are crucial for adaptive behaviors and academic achievement.
• Executive function deficits are associated with Attention Deficit Hyperactivity Disorder (ADHD), but not typically with Oppositional Defiant Disorder/Conduct Disorder (ODD/CD).

Purpose of the Study:

• To investigate the relationship between executive function, adaptive behaviors, and academic achievement in adolescents with ADHD and/or ODD/CD.
• To compare executive function and adaptive behavior profiles across ADHD only, ODD/CD only, comorbid ADHD and ODD/CD, and control groups.

Main Methods:

• A sample of 110 adolescents was divided into four groups: ADHD only, ADHD and ODD/CD, ODD/CD only, and a control group.
• Assessment included the Vineland Adaptive Behaviour Scales for socialisation and communication skills, reading ability tests, and executive functioning tests.

Main Results:

• Adolescents with ADHD exhibited poorer adaptive communication skills compared to ODD/CD or control groups.
• ADHD was associated with lower word recognition, while ODD/CD did not impact reading levels compared to controls.
• Executive function test scores correlated with all adaptive behavior outcomes, with executive function significantly predicting adaptive behavior, communication, and socialization.

Conclusions:

• Findings suggest ADHD specifically impacts adaptive communication and social competence, with executive function playing a key predictive role.
• Further research with diverse samples is required to confirm generalizability, and larger samples are needed to explore gender differences.
