The purpose of this study is to examine the alternate forms reliability of the AMPS (Assessment of Motor and Process Skills) (Fisher, 1997a) where alternate forms means different pairs of AMPS tasks. The participants for this study were persons selected from the AMPS database who had performed four AMPS tasks. The participants varied in age, gender, diagnosis, and level of assistance needed to live in the community. The AMPS was administered by trained and calibrated occupational therapists according to standardized procedures. The data for the 91 participants were subjected to 12 many-faceted Rasch analyses to generate ADL motor and ADL process ability measures for each task and each set of paired tasks. Repeated measures ANOVAs revealed no time effect across the four AMPS tasks. Pearson product moment correlations between Tasks 1 and 2 combined and Tasks 3 and 4 combined were r = .91 and r = .86 for the ADL motor and ADL process scales, respectively. Calculation of the standardized difference (z) revealed that no more than 8% of the participants had ADL motor or ADL process ability measures that differed significantly between observations once we accounted for real differences in a persons performance; 80% of the paired ADL motor and ADL process ability measures remained stable within +/- 0.5 logits when the participants performed two tasks. The AMPS ADL motor and ADL process scales can be used reliably in clinical practice and for research purposes.
本研究的目的是检验AMPS（运动与过程技能评估）（Fisher，1997a）的复本信度，其中复本是指不同的AMPS任务对。本研究的参与者是从AMPS数据库中选取的完成了四项AMPS任务的人员。参与者在年龄、性别、诊断以及在社区生活所需的协助水平方面存在差异。AMPS由经过培训和校准的职业治疗师按照标准化程序进行施测。对91名参与者的数据进行了12次多面Rasch分析，以生成每项任务以及每组配对任务的ADL运动和ADL过程能力测量值。重复测量方差分析显示，在四项AMPS任务中不存在时间效应。ADL运动量表和ADL过程量表中，任务1和任务2组合与任务3和任务4组合之间的Pearson积差相关系数分别为r = .91和r = .86。标准化差异（z）的计算表明，在考虑了个体表现的实际差异后，不超过8%的参与者在两次观察中的ADL运动或ADL过程能力测量值存在显著差异；当参与者完成两项任务时，80%的配对ADL运动和ADL过程能力测量值在+/- 0.5 logits范围内保持稳定。AMPS的ADL运动量表和ADL过程量表可在临床实践和研究中可靠使用。
