Abstract
- Background Prenatal exposure to alcohol often results in disruption to discrete cognitive and behavioral domains, including executive function ( EF) and adaptive functioning. In the current study, the relation between these 2 domains was examined in children with histories of heavy prenatal alcohol exposure, nonexposed children with a diagnosis of attention-deficit/hyperactivity disorder ( ADHD), and typically developing controls. Methods As part of a multisite study, 3 groups of children (8 to 18 years, M = 12.10) were tested: children with histories of heavy prenatal alcohol exposure ( ALC, n = 142), nonexposed children with ADHD ( ADHD, n = 82), and typically developing controls ( CON, n = 133) who did not have ADHD or a history of prenatal alcohol exposure. Children completed subtests of the Delis- Kaplan Executive Function System ( D- KEFS), and their primary caregivers completed the Vineland Adaptive Behavior Scales- II. Data were analyzed using regression analyses. Results Analyses showed that EF measures were predictive of adaptive abilities, and significant interactions between D- KEFS measures and group were present. For the ADHD group, the relation between adaptive abilities and EF was more general, with 3 of the 4 EF measures showing a significant relation with adaptive score. In contrast, for the ALC group, this relation was specific to the nonverbal EF measures. In the CON group, performance on EF tasks did not predict adaptive scores over the influence of age. Conclusions These results support prior research in ADHD, suggesting that EF deficits are predictive of poorer adaptive behavior and extend this finding to include children with heavy prenatal exposure to alcohol. However, the relation between EF and adaptive ability differed by group, suggesting unique patterns of abilities in these children. These results provide enhanced understanding of adaptive deficits in these populations, as well as demonstrate the ecological validity of laboratory measures of EF. [ABSTRACT FROM AUTHOR]
