This secondary analysis quantified the psychometric properties of the Ohio Modified Arm-Motor Ability Test (OMAAT) in a sample of neurologically stable chronic stroke survivors (n = 67, 40 men; mean age 59.8 yr, standard deviation = 12.8; 42 White, 23 Black, 2 other; 92.5% right-sided lesion; 44 ischemic stroke). Findings indicate high OMAAT internal consistency (Cronbach's α = .97, ordinal α = .98, Gugiu's bootstrap reliability = .97), unidimensionality, and strong positive factor loadings for all 20 OMAAT items. Convergent validity between OMAAT and Action Research Arm Test total scores was strong (r = .90, p < .0001). The OMAAT is the first short measure of upper extremity functional limitation available to clinicians and researchers that includes an administration manual and that has been examined using nonparametric psychometrics. A detailed administration manual is provided as a supplement to this article.
这项二次分析对俄亥俄改良手臂运动能力测试（OMAAT）在神经功能稳定的慢性卒中幸存者样本（n = 67，40名男性；平均年龄59.8岁，标准差 = 12.8；42名白人，23名黑人，2名其他种族；92.5%为右侧病变；44例缺血性卒中）中的心理测量学特性进行了量化。研究结果表明OMAAT具有较高的内部一致性（克朗巴哈α系数 = 0.97，序数α系数 = 0.98，古吉乌自助法可靠性 = 0.97）、单维度性，并且OMAAT的所有20个项目都具有很强的正向因子载荷。OMAAT与动作研究手臂测试总分之间的收敛效度很强（r = 0.90，p < 0.0001）。OMAAT是临床医生和研究人员可获得的首个用于评估上肢功能受限的简短测量工具，它包含一份施测手册，并且已使用非参数心理测量学方法进行了检验。本文提供了一份详细的施测手册作为补充内容。
