Insights
Preschool children with attention-deficit hyperactivity disorder (ADHD) symptoms and lower social competence had poorer cognitive function. Inattention, with or without hyperactivity, was linked to significantly lower cognitive scores.
Area of Science:
- Child Psychology
- Developmental Neuroscience
- Pediatric Health
Background:
- Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder affecting children.
- Social competence is crucial for a child's development and well-being.
- Cognitive function in early childhood is a predictor of later academic and life success.
Purpose of the Study:
- To investigate the association between ADHD symptoms and social competence with cognitive status in preschoolers.
- To examine how different ADHD subtypes relate to cognitive function.
- To understand the impact of behavioral issues on early cognitive development.
Main Methods:
- Study involved 457 preschool children from three Spanish birth cohorts (INMA project).
- Cognitive functions assessed using McCarthy Scales of Children's Abilities (MSCA) at age 4.
- ADHD symptoms (DSM-IV criteria) and social competence (California Preschool Social Competence Scale) evaluated by teachers.
Main Results:
- General ADHD symptoms and poorer social competence were negatively associated with cognitive outcomes.
- Children with inattention symptoms alone showed lower cognitive scores compared to those without ADHD.
- Children with both inattention and hyperactivity symptoms had significantly lower cognitive function scores.
Conclusions:
- Behavioral dysfunctions, including ADHD symptoms and social incompetence, are associated with impaired cognitive functions in preschoolers.
- Early identification and intervention for ADHD symptoms and social competence issues may be important for supporting cognitive development.
- Findings highlight the interconnectedness of behavioral and cognitive development in early childhood.
Abstract:
We aimed to investigate the association of attention-deficit hyperactivity disorder (ADHD) symptoms and social competence outcomes with cognitive status in preschool children. The study population was drawn from three birth cohorts belonging to the Spanish INMA (Infancia y Medio Ambiente) project: Menorca (n = 289), Ribera d'Ebre (n = 60), and Granada (n = 108). Children were assessed at the age of 4 years for cognitive functions (McCarthy Scales of Children's Abilities, MSCA) by psychologists and for inattention and hyperactivity symptoms (ADHD Criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, ADHD-DSM-IV) and social competence (California Preschool Social Competence Scale) by their teachers. Multiple regression analyses were conducted to examine potential associations between behavioral outcomes (ADHD symptoms and social competence) and MSCA cognitive outcomes, adjusting for confounders. The presence of general ADHD symptoms (inattention, hyperactivity, or both) and poorer social competence both showed negative associations with cognitive outcomes. When we compared children according to ADHD subtypes, those with inattention symptoms alone and those with both inattention and hyperactivity symptoms showed significantly lower cognitive function scores in comparison to children with no ADHD symptoms. Behavioral dysfunctions in preschoolers may be associated with impairment of cognitive functions.

Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Autism Spectrum Disorder
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.
