The Finger Tapping Test (FTT) is a widely utilized measure to assess lateralized motor speed and dexterity. The current study sought to cross-validate an abbreviated version of the FTT (i.e., of Trials 3-5) and to evaluate a novel abbreviated method (i.e., of three trials within five taps of each other; "3 within 5") to examine their respective effectiveness as a predictor of full-score performance based on a traditional administration procedure. The results showed that the abbreviated methods accurately predicted the full-test score, and any statistically significant differences that emerged were small based on effect size analysis and unlikely to be clinically meaningful. These findings were consistent across genders, among older adults, and among individuals displaying significant inter-trial tapping variability and thus requiring lengthier administration time. Classification accuracy statistics for the detection of impairment and performance validity status were high for both abbreviated methods. The results support two valid options for shortening the duration of the FTT. Both methods, used independently or in combination, are compatible with traditional administration procedures.
指弹测试（FTT）是一种广泛用于评估侧化运动速度和灵巧性的测量方法。本研究旨在对 FTT 的简化版本（即 3-5 次试验中的 ）进行交叉验证，并评估一种新的简化方法（即连续五次敲击中三个试验；“3 within 5”），以根据传统的施测程序来检验它们作为全分数表现的预测指标的各自有效性。结果表明，简化方法准确地预测了全测试分数，而且任何出现的统计学显著差异都是基于效应量分析的较小差异，不太可能具有临床意义。这些发现在性别、老年人以及表现出显著的试验间敲击变异性的个体中是一致的，因此需要更长的施测时间。对于两种简化方法，检测损伤和表现有效性状态的分类准确性统计数据都很高。结果支持缩短 FTT 时长的两种有效选择。这两种方法可单独或组合使用，与传统的施测程序兼容。
