To evaluate cross-regional validity of the Assessment of Motor and Process Skills (AMPS) with a specific focus on valid use with Middle Europeans.
Descriptive cross-regional validation study.
A total of 1346 participants from Middle Europe and 144,143 participants from North America, UK/Ireland, the Nordic Countries, other Europe, Australia/New Zealand and Asia, between the ages of 3 and 103 years, in good health and with a variety of diagnoses, were selected from the AMPS database.
Many-facet Rasch analysis was used to analyse participant raw data, and effect sizes were used to evaluate for differential item functioning. Evaluation for differential test functioning was also implemented.
None of the 20 activity of daily living process items, and only one of the activity of daily living motor items demonstrated differential item functioning. The activity of daily living motor item Aligns exceeded the significant effect size criterion of ± 0.55 logit, but the significant differential item functioning did not lead to differential test functioning (i.e. all measures fell within the 95% confidence bands).
This study provides further evidence of validity of the AMPS when used to evaluate quality of daily living performance across world regions. The AMPS measures can be used as objective indices of activity of daily living ability in rehabilitation settings and in international collaborative research related to activity of daily living task performance.
评估运动和过程技能评估（AMPS）的跨区域有效性，特别关注其在中欧人群中的有效应用。
描述性跨区域验证研究。
从 AMPS 数据库中选择了来自中欧的 1346 名参与者和来自北美、英国/爱尔兰、北欧国家、其他欧洲、澳大利亚/新西兰和亚洲的年龄在 3 至 103 岁之间、身体健康且有多种诊断的共 144143 名参与者。
采用多方面 Rasch 分析对参与者的原始数据进行分析，并使用效应大小评估项目功能差异。还实施了测试功能差异的评估。
20 项日常生活活动过程项目中没有一项，只有一项日常生活活动运动项目显示出项目功能差异。日常生活活动运动项目 Aligns 超过了±0.55 对数单位的显著效应大小标准，但显著的项目功能差异并未导致测试功能差异（即所有测量值均在 95%置信带内）。
本研究进一步证明了 AMPS 在评估世界各地区日常生活表现质量时的有效性。AMPS 测量可以作为康复环境中日常生活能力的客观指标，并可用于与日常生活任务表现相关的国际合作研究。
