传统的执行功能神经心理学测量方法难以应用于功能成像和临床试验，具有巨大的实践效果。它们的敏感性和特异性也很差，而重测信度通常不在基于计算机的测试中评估。本研究评估了一种新的参数Go/No-Go（PGNG）任务的一些心理测量学特性。PGNG包括三个难度级别，分别评估注意力、定势转换和处理速度，另外两个难度级别评估抑制控制。在两个地点共招募了63名健康对照参与者，以评估PGNG的心理测量学特性。PGNG被认为具有坚实的参数特征和较强的重测信度。适度的收敛效度也证明了与其他执行功能测试。学习效果显着低于连线测验。本研究结果为PGNG的效度和信度提供了初步的支持。
Traditional neuropsychological measures of executive functioning are difficult to employ in functional imaging and clinical trial contexts and have tremendous practice effects. They also have poor sensitivity and specificity, while test-retest reliability is often not assessed in computer-based tests. The present study evaluates some psychometric properties of a new Parametric Go/No-Go (PGNG) Task. The PGNG consists of three levels of difficulty assessing attention, set-shifting, and processing speed, with the two more difficult levels assessing inhibitory control. A total of 63 healthy control participants were recruited at two sites to evaluate the psychometric properties of the PGNG. The PGNG was found to have solid parametric characteristics and strong test-retest reliability. Modest convergent validity was also demonstrated with other executive-functioning tests. Learning effects were significantly less than those for the Trail Making Test. The present results provide solid initial support for the validity and reliability of the PGNG.
