Is the discrepancy criterion for defining developmental disorders valid?

Article Abstract:

Most of the development disorders are defined by an achievement discrepancy rather than measurable deviations, exceeding a threshold, from normal development. An assessment of parameters that determine variability across abilities and assessment of relationships between achievement discrepancies and behavioral disturbances by examining 390 children aged 3 to 12 years for five ability constructs and nine behavioral disturbances shows that underachievement on one or more abilities, not unequal achievement across abilities, is invariably associated with behavioral disturbance.
