Social skills and executive function among youth with sickle cell disease: a preliminary investigation.

OBJECTIVES: To explore the relationship between executive function (EF) and social skills in youth with sickle cell disease (SCD). METHODS: 20 youth with SCD completed objective tests of EF (Tasks of Executive Control; Animal Sorting subtest from the Developmental Neuropsychological Assessment-Second Edition), an IQ screener, and paper-and-pencil measures of social skills (Social Skills Improvement System [SSIS]). Primary caregivers completed paper-and-pencil measures of EF (Behavior Rating Inventory of Executive Function) and social skills (SSIS). RESULTS: EF scores from the Behavior Rating Inventory of Executive Function related to parent- and child-reported social skills such that EF deficits correlated with poorer overall and domain-specific social skills. Similarly, EF scores from the Animal Sorting test related to child-reported social skills. Worse parent-reported EF predicted worse parent-reported social skills above the variance accounted for by IQ. CONCLUSIONS: EF is related to social skills and may be necessary for successful social interaction among youth with SCD. These results provide rationale and guidance for future larger-scale investigations of EF and social skills among children with SCD.
