Inter-relationships between executive functions and functional impairments among children with ADHD: findings from a network perspective

Key findings from this study

• The study found that Monitoring and Planning executive functions exhibited the highest influence on the broader network of executive and functional impairments.
• The researchers demonstrate that family-related functional impairments and inhibition deficits function as bridge nodes, connecting executive function deficits to broader functional consequences.
• The authors report that self-concept impairment affected the largest proportion of children (15.1%), whereas risky behavior showed the lowest prevalence (0.4%).

Overview

Network analysis identified critical executive functions and functional impairments in children with ADHD, revealing hierarchical relationships across cognitive and behavioral domains. The study mapped interconnections between executive function deficits and real-world functional impairments to guide intervention prioritization.

Methods and approach

Researchers recruited 225 children with ADHD diagnosed through semi-structured interview from a pediatric hospital in China. Executive functions were assessed using the Behavior Rating Inventory of Executive Function-Parent Form. Functional impairments were measured using the Weiss Functional Impairment Scale-Parent Form. Network analysis identified central and bridge nodes through Expected Influence and bridge Expected Influence indices.

Results

Monitoring and Planning emerged as the most influential executive function domains (Expected Influence = 1.11 and 1.07, respectively), occupying central positions in the network model. Functional impairments varied substantially across domains, ranging from 0.4% prevalence for risky behavior to 15.1% for self-concept impairment. Family-related impairments and Inhibition deficits served as the strongest bridge nodes linking executive function and functional impairment communities (bridge Expected Influence = 0.41 and 0.38, respectively), indicating their integrative role in the symptom network.

Implications

The identification of Monitoring and Planning as central domains suggests these executive functions warrant prioritized assessment and intervention focus in clinical and research settings. The bridging role of family-related impairments and inhibition deficits indicates that interventions targeting inhibitory control may generate cascading improvements across functional domains, particularly family functioning. Network-derived hypotheses provide empirical foundations for designing mechanism-focused interventions that address specific executive function bottlenecks rather than global executive dysfunction.
