Although extant studies indicate that there is a strong association between attention deficit/hyperactivity disorder and reading ability in elementary school children, knowledge regarding the relation between inattentive and hyperactive/impulsive behaviors and emergent literacy in preschool children is less established. This study examined the unique and overlapping relations between measures that assess inattention and hyperactivity/impulsivity and emergent literacy skills in preschool children. Participants included 204 preschool children (M age = 56 months, 50.9% female, 79.8% European American). Behavioral rating scales were completed by teachers, and the Continuous Performance Test (CPT) and the Test of Preschool Early Literacy were completed by the preschoolers. Across measures, inattention was a unique correlate of emergent literacy skills, whereas hyperactivity/impulsivity was not. Both rating scales and the CPT indices of inattention were uniquely associated with emergent literacy skills. These results suggest that these measures are assessing different manifestations of inattention that are both unique correlates of early reading skills. (author abstract)
