虽然标准的200个项目版本的起搏听觉序列加法任务（PASAT）是一种敏感的神经心理学工具，但由于其长度和逐渐增加的难度，它可能会让一些患者感到非常厌恶。我们提出了人口统计学校正的规范为50和100项目的简短形式的版本在560名神经正常的成年人的样本。年龄、教育和种族在786名HIV感染成人的临床样本中，50项、100项和200项版本的诊断准确性基本相同（使用综合神经心理成套测验的临床评级作为金标准，三个PASAT版本的总体分类率分别为71%，74%，特异性（89-92%）优于敏感性（46-53%）。50个项目的版本显示出适度的天花板效应。但100项测试却没有。在40名受试者的混合临床样本中，50项版本的给药速度是200项版本的两倍多，并且耐受性更好（不适评分为4.0与5.9在10点量表上，p
While the standard 200-item version of the Paced Auditory Serial Addition Task (PASAT) is a sensitive neuropsychological instrument, it can be quite aversive to some patients due to its length and progressively increasing difficulty. We present demographically-corrected norms for 50 and 100-item short-form versions in a sample of 560 neurologically normal adults. Age, education, and ethnicity (but not gender) were found to be significant predictors of performance.In a clinical sample of 786 HIV-infected adults, diagnostic accuracy of the 50, 100, and 200-item versions was essentially equivalent (using clinical ratings of a comprehensive neuropsychological battery as the gold standard, overall classification rates of the three PASAT versions were 71%, 74%, and 73%, respectively), with better specificity (89-92%) than sensitivity (46-53%). The 50-item version showed moderate ceiling effects. but the 100-item test did not.In a mixed clinical sample of 40 subjects, the 50-item version was administered more than twice as fast as the 200-item version, and was tolerated better (discomfort rating of 4.0 vs. 5.9 on a 10-point scale, p
