Practice effects in serial neuropsychological assessment have led to the use of alternate forms to measure change in cognitive functioning. The construct validity of three variants of the Trail Making Test was explored over a 3-week period in a sample of 158 undergraduate students. Using confirmatory factor analysis, a two-factor (sequencing-shifting) model was identified to best represent the data. Latent means structural analysis indicated the absence of order effects, lending support for the construct validity of the three tests. The study provides evidence that the three tests can be offered as potential alternative instruments in serial assessment.
在连续的神经心理学评估中，练习效应导致使用交替形式来衡量认知功能的变化。在 158 名大学生样本中，在 3 周的时间内探索了三种变体的连线测试的构念效度。使用验证性因素分析，确定了一个两因素（顺序转换）模型来最好地表示数据。潜在均值结构分析表明不存在顺序效应，这为三个测试的构念效度提供了支持。该研究提供了证据，表明这三个测试可以作为连续评估的潜在替代工具。
