背景和目的。连续标尺身体功能性能测试(CS-PFP)可用于获得有效、可靠和灵敏的身体功能容量测量。这项测试需要一个固定的实验室空间和大约1个小时的管理。这项研究分4个步骤进行，或者说子研究，以开发和验证一个简短的、基于社区的版本(PFP-10)，它比CS-PFP需要更少的空间和设备。研究对象和方法。报告了实施CS-PFP或PFP-10的男性和女性的回顾数据(n=228)和前瞻性数据(n=91)。一项为期12周的锻炼计划被用来检查对变化的敏感性。数据分析使用配对t检验、皮尔逊相关、组内相关系数(ICC)和增量指数(DI)程序。结果。PFP-10总分和5个领域中有4个领域的得分与CS-PFP有统计学上的相似性(在3%以内)。PFP-10上身力量领域得分低17%，但高度相关(ICC=0.97)。社区和已建立的实验室PFP-10得分相似(ICC=.85-.97)。PFP-10对变化也很敏感(DI=.21-.54)。讨论和结论。PFP-10产生有效、可靠和灵敏的测量结果，可以自信地取代CS-PFP。
Background and Purpose. The Continuous-Scale Physical Functional Performance Test (CS-PFP) can be used to obtain valid, reliable, and sensitive measurements of physical functional capacity. This test requires a fixed laboratory space and approximately 1 hour to administer. This study was carried out in 4 steps, or substudies, to develop and validate a short, community-based version (PFP-10) that requires less space and equipment than the CS-PFP. Subjects and Methods. Retrospective data (n = 228) and prospective data (n = 91) on men and women performing the CS-PFP or the PFP-10 are reported. A 12-week exercise program was used to examine sensitivity to change. Data analyses were done using paired t-test, Pearson correlation, intraclass correlation coefficient (ICC), and delta index (DI) procedures. Results. The PFP-10 total score and 4 of the 5 domain scores were statistically similar (within 3%) to those of the CS-PFP. The PFP-10 upper-body strength domain score was 17% lower, but was highly correlated (ICC = .97). Community and established laboratory PFP-10 scores were similar (ICC = .85-.97). The PFP-10 also is sensitive to change (DI = .21-.54). Discussion and Conclusion. The PFP-10 yields valid, reliable, and sensitive measurements and can be confidently substituted for the CS-PFP.
