Despite reports of academic difficulties in children with attention-deficit/hyperactivity disorder (ADHD), little is known about the relationship between performance on tests of academic achievement and measures of attention. The current study assessed intellectual ability, parent-reported inattention, academic achievement, and attention in 45 children (ages 7-15) diagnosed with ADHD. Hierarchical regressions were performed with selective, sustained, and attentional control/switching domains of the Test of Everyday Attention for Children as predictor variables and with performance on the Wechsler Individual Achievement Test-Second Edition as dependent variables. It was hypothesized that sustained attention and attentional control/switching would predict performance on achievement tests. Results demonstrate that attentional control/ switching accounted for a significant amount of variance in all academic areas (reading, math, and spelling), even after accounting for verbal IQ and parent-reported inattention. Sustained attention predicted variance only in math, whereas selective attention did not account for variance in any achievement domain. Therefore, attentional control/switching, which involves components of executive functions, plays an important role in academic performance.
尽管有报道称患有注意力缺陷多动障碍(ADHD)的儿童存在学业困难,但对于学业成绩测试表现与注意力测量之间的关系却知之甚少。当前研究评估了45名被诊断患有ADHD的儿童(年龄在7至15岁之间)的智力、家长报告的注意力不集中情况、学业成绩和注意力。以儿童日常注意力测试的选择性、持续性和注意力控制/转换领域作为预测变量,以韦氏个别成就测验第二版的表现作为因变量进行了分层回归分析。研究假设持续性注意力和注意力控制/转换能够预测成就测试的表现。结果表明,即使在考虑了言语智商和家长报告的注意力不集中情况之后,注意力控制/转换在所有学业领域(阅读、数学和拼写)中仍占显著比例的方差。持续性注意力仅在数学方面预测了方差,而选择性注意力在任何成就领域中均未解释方差。因此,涉及执行功能成分的注意力控制/转换在学业表现中起着重要作用。
