There is little assessment to provide specific information about quality of bilateral upper extremity movement specifically. This study examined the psychometric properties of the Yonsei-Bilateral Activity Test (Y-BAT). An observational cross-sectional design was used with 100 stroke survivors. Unidimensionality was examined using factor analyses, and Rasch analysis was used to test rating scale structure, fit statistics, and precision of the Y-BAT. The Y-BAT demonstrated a unidimensional measurement construct, and 19 of the 27 items fit the Rasch model. The instrument demonstrated good precision, including person reliability and person strata. The Y-BAT estimated person measures within a wide range of theta values with a reliability of .9 with good precision. Our results indicate that a revised, 19-item version of the Y-BAT demonstrates sound internal validity and may be a useful instrument for clinicians to measure upper extremity function with good precision following stroke.
目前几乎没有评估方法能够专门提供关于双侧上肢运动质量的具体信息。本研究旨在检验延世双侧活动测试（Y-BAT）的心理测量学特性。采用观察性的横断面设计，共纳入 100 例脑卒中幸存者。采用因子分析检验单维性，采用 Rasch 分析检验评定量表结构、适配统计和 Y-BAT 的精确性。Y-BAT 显示出单维测量结构，27 个项目中有 19 个符合 Rasch 模型。该工具具有良好的精确性，包括个体可靠性和个体层次。Y-BAT 在 theta 值的广泛范围内估计个体测量值，可靠性为.9，精确性良好。研究结果表明，修订后的、包含 19 个项目的 Y-BAT 具有良好的内部有效性，可能是一种有用的工具，可用于评估脑卒中后上肢功能，具有良好的精确性。
