Abstract
Objective: The Halstead Category Test (HCT) has been demonstrated to be sensitive to executive dysfunction in adults and children. Children with a history of significant prenatal alcohol exposure (PAE) typically show deficits in executive functions in such areas as abstract reasoning, concept formation abilities, and cognitive flexibility. However, earlier research has not taken into account the demographic variables of age, sex, and ethnicity. Methods: Three groups of psychiatrically hospitalized children ages 9–17 years were included: Children with a history of PAE (n = 295); children with cognitive impairment but no suspected history of PAE (n = 201); and children without suspected cognitive impairment (n = 317). All children completed a series of neuropsychological tests including the HCT and the Wechsler Intelligence Scale for Children-IV (WISC-IV). Results: Children with a history of PAE and cognitively impaired children with no history of PAE produced significantly more HCT errors across all ages than the cognitively unimpaired group. There were no significant effects of ethnicity or gender. Age and Working Memory Index were negatively correlated with HCT errors. Conclusion: The findings support the use of the HCT as a sensitive measure of executive functions in both PAE and non-PAE cognitively impaired children with no evidence of gender and ethnic bias. Use of the HCT is indicated in future research to measure improvement in executive functioning among children with a history of PAE facilitated by education, rehabilitation, and other forms of training and treatment.Keywords
