Wechsler profiles in referred children with intellectual giftedness: Associations with trait-anxiety, emotional dysregulation, and heterogeneity of Piaget-like reasoning processes.

Background/purpose: It is common that intellectually gifted children (IQ ≥ 130) are referred to paediatric or child neuropsychiatry clinics for socio-emotional problems and/or school underachievement or maladjustment. Among them, those displaying developmental asynchrony - a heterogeneous developmental pattern reflected in a significant verbal-performance discrepancy (SVPD) on Wechsler's intelligence profile - are thought to be more emotionally and behaviourally impaired than others. Our purpose was to investigate this clinical dichotomy using a cognitive psychopathological approach.

Methods: Trait-anxiety and emotional dysregulation were investigated in two groups of referred gifted children (n = 107 and 136, respectively), a pilot-study of reasoning processes on extensive Piaget-like tasks was also performed in an additional small group (n = 12).

Results: Compared to those with a homogenous Wechsler profile, children with a SVPD exhibited: 1) a decreased prevalence of social preoccupation-anxiety (11.1% versus 27.4%; p < 0.05); 2) an increased prevalence of emotional dysregulation (58.7% versus 41.3%; p < 0.05); and 3) an increased prevalence of pathological cognitive disharmony on Piaget-like tasks (87.5% versus 0.0%; p < 0.05).

Conclusion: The results support a clinical dichotomy of behaviourally-impaired children with intellectual giftedness, with developmentally asynchronous ones exhibiting more severe psychopathological features. This suggests that developmental asynchrony matters when examining emotional and behavioural problems in gifted children and call for further investigation of this profile.
