电话认知成套测验对大规模筛查和流行病学研究是有用的，但其简短和缺乏内容深度可能会导致心理测量的局限性，阻碍其实用性。本研究通过使用现代心理测量方法重新调整成人电话认知简易测试（BTACT），解决了其中的一些局限性。档案数据来自美国认知项目中年发展全国调查中的4，212名28-84岁志愿者的全国样本。我们将一个双因素模型拟合到项目级、子尺度级和尺度级数据的组合。最佳拟合模型包含一个一般因子和次要因子，用于捕获数字系列、红/绿色测试和雷伊听觉言语学习测试的特定测试方法效应或残差相关性。从这个模型产生的因素得分与传统的BTACT分数进行了比较。重要的分数差异（即，>0.3个标准偏差单位）。当根据一些临床和人口统计学标准变量进行判断时，双因素评分显示出比传统BTACT评分略高的上级有效性。现代的心理测量方法来评分的BTACT线性缩放和适度的标准效度优势的好处。
Telephone cognitive batteries are useful for large-scale screening and epidemiological studies, but their brevity and lack of content depth may cause psychometric limitations that hinder their utility. The current study addressed some of these limitations by rescaling the Brief Test of Adult Cognition by Telephone (BTACT) using modern psychometric methods. Archival data were obtained from a national sample of 4,212 28-84-year-old volunteers in the National Survey of Midlife Development in the United States Cognitive Project. We fit a bi-factor model to a combination of item-level, subscale-level, and scale-level data. The best fitting model contained a general factor and secondary factors capturing test-specific method effects or residual correlations for Number Series, Red/Green Test, and the Rey Auditory Verbal Learning Test. Factor scores generated from this model were compared with conventional BTACT scores. Important score differences (i.e., >0.3 standard deviation units) were found in 28% of the sample. The bi-factor scores demonstrated slightly superior validity than conventional BTACT scores when judged against a number of clinical and demographic criterion variables. Modern psychometric approaches to scoring the BTACT have the benefit of linear scaling and a modest criterion validity advantage.
