我们在患有注意力缺陷/多动障碍（ADHD）的儿童（ADHD）的儿童中进行了荟萃分析回顾47个持续绩效测试（CPT）表现的组间研究。使用随机效应模型并纠正采样误差和测量不可靠性，我们发现了整体性能的大效应大小（Delta），但在少数研究数据的研究中，随着时间的推移，效果较小至中度的三角洲。随着时间的推移，较小的delta s可能部分归因于广泛使用刺激，而刺激很容易区分目标和干扰物。在观察到的delta s中，伪影占了相当大的差异。由于存在未经校正的伪影，并强调了未来工作中的人为差异，以确定ADHD中真正的神经认知异质性的数量，因此对先前评论中报告的效应大小显着减弱。信号检测理论和扩散建模分析表明，与ADHD相关的缺陷是由于感知敏感性降低（D'）和较慢的漂移速率（V）。结果被解释了几种多动症模型的上下文。
We meta-analytically review 47 between-groups studies of continuous performance test (CPT) performance in children with attention-deficit/hyperactivity disorder (ADHD). Using a random effects model and correcting for both sampling error and measurement unreliability, we found large effect sizes (delta) for overall performance, but only small to moderate delta for performance over time in the handful of studies that reported that data. Smaller delta s for performance over time are likely attributable, in part, to the extensive use of stimuli for which targets and distractors are quite easily differentiated. Artifacts accounted for a considerable proportion of variance among observed delta s. Effect sizes reported in previous reviews were significantly attenuated because of the presence of uncorrected artifacts and highlight the necessity of accounting for artifactual variance in future work to determine the amount of true neurocognitive heterogeneity within ADHD. Signal detection theory and diffusion modeling analyses indicated that the ADHD-related deficits were because of decreased perceptual sensitivity (d') and slower drift rates (v). Results are interpreted the context of several recent models of ADHD.
