Achievement discrepancies are not linked to behavioral issues in children. However, underachievement relative to peers consistently correlates with behavioral disturbances, suggesting a need to redefine developmental disorders.

Area of Science:

  • Developmental Psychology
  • Child Psychiatry
  • Neurodevelopmental Disorders

Background:

  • Developmental disorders often defined by achievement discrepancy: ability significantly below measured intelligence.
  • Current definitions require evaluation of variability across abilities and links to behavioral disturbances.

Purpose of the Study:

  • Assess the validity of the achievement discrepancy criterion for defining developmental disorders.
  • Examine the relationship between achievement discrepancies and behavioral disturbances in children.

Main Methods:

  • Administered intelligence, language, motor, empathic, and attentional control measures to 390 children (ages 3-12).
  • Collected parent ratings of child behavior.

Main Results:

  • Achievement discrepancies depend on ability measure correlations, distribution shapes, and dimensional positioning.
  • No direct relationship found between achievement discrepancies and behavioral disturbance.
  • Underachievement relative to age peers strongly correlated with behavioral disturbance.

Conclusions:

  • Developmental disorders require redefinition, aligning with the definition of Intellectual Disability.
  • Redefinition should incorporate underachievement of a defined magnitude.
  • Utilize standardized measures with known developmental relations and concurrent impaired function deficits.
