目的：随着康复中标准化结果工具的使用越来越多，经常出现的问题是如何解释这些标准化结果工具得出的分数。本文使用的例子，从急性护理后的活动措施，以说明4种不同的数据分析和呈现策略，可用于产生有意义的结果数据，用于康复研究和实践。设计图：一项前瞻性队列研究，在从大型急性护理医院出院时或从马萨诸塞州大波士顿地区的急性护理医院出院后进入2家康复医院之一的患者中招募。样本：康复结果研究中的516名受试者。结果如下：描述了四种不同的方法来分析和报告结果数据，以获得更有意义的结果测量：解释单一量表评分;解释评分变化的临床意义;百分位数排名方法;和功能分期方法。前3种方法侧重于解释个体测量的数值属性，最适合评估个体结果和检测变化。第四，功能分期方法，提供了一个有吸引力的特点，解释临床意义提供了一个特定的定量评分，而不牺牲的内在价值的定量尺度随时间的变化进行跟踪。结论：鼓励用户考虑他们可用的分析和呈现策略的范围，以从定量和内容的角度评估标准化量表分数。
Objective: With the increased use of standardized outcome instruments in rehabilitation, questions frequently arise as to how to interpret the scores that are derived from these standardized outcome instruments. This article uses examples drawn from the Activity Measure for Post Acute Care to illustrate 4 different data analysis and presentation strategies that can be used to yield meaningful outcome data for use in rehabilitation research and practice. Design: A prospective cohort study in patients recruited at the point of discharge from a large acute care hospital or on admission to 1 of 2 rehabilitation hospitals after discharge from an acute care hospital in the greater Boston, MA region. Sample: A total of 516 subjects in the Rehabilitation Outcome Study. Results: Four distinct approaches to analyzing and reporting outcome data are described to derive more meaningful outcome measurements: interpreting a single scale score; interpreting clinical significance of score changes; a percentile ranking method; and a functional staging approach. The first 3 methods focus on interpreting the numeric property of individual measurements and are best suited to assess individual outcomes and for detecting change. The fourth, a functional staging approach, provides an attractive feature of interpreting the clinical meaning provided by a particular quantitative score without sacrificing the inherent value of a quantitative scale for tracking change over time. Conclusion: Users are encouraged to consider the range of analysis and presentation strategies available to them to evaluate a standardized scale score, both from a quantitative and a content perspective.
