Beyond the Overlap: Understanding the Empirical Association Between ADHD Symptoms and Executive Function Impairments...

Area of Science:

• Child Psychology
• Neurodevelopmental Disorders
• Cognitive Science

Background:

• Executive function (EF) difficulties are increasingly recognized as closely linked to Attention-Deficit/Hyperactivity Disorder (ADHD).
• Rating scales are commonly used to assess both ADHD symptoms and EF impairments.

Purpose of the Study:

• To investigate the nature of the associations between ADHD symptoms and EF difficulties in children.
• To determine if these associations stem from construct overlap or phrasing similarity between assessment tools.

Main Methods:

• Utilized the Conners 3 Rating Scales for ADHD symptoms and the Executive Function Questionnaire (EFQU) for EF impairments.
• Analyzed data from 1068 children aged 7-14 years, using parent and teacher ratings.
• Conducted exploratory and confirmatory factor analyses to assess construct distinctiveness.

Main Results:

• Strong correlations were found between inattentive ADHD symptoms and EF difficulties across multiple domains, as reported by parents and teachers.
• Factor analyses demonstrated that the Conners 3 and EFQU measure distinct latent dimensions with minimal item overlap.
• Teachers' ratings offered more integrated behavioral views, while parents distinguished ADHD and EF traits more clearly.

Conclusions:

• ADHD symptoms and EF impairments are empirically intertwined in children's everyday functioning, despite being conceptually distinct.
• Findings support the importance of multi-informant assessment (parents and teachers) for a comprehensive understanding.
• Contextual variability in reporting underscores the need to consider different perspectives when evaluating children's functioning.
