本研究探讨了收敛结构效度的一个新的性能为基础的评估工具，称为全面的高水平活动的流动性预测（CHAMP）作为衡量高水平的流动性服务成员（SM）与创伤性下肢损失（LLL）。该研究由118名SM完成。使用6分钟步行试验（6MWT）作为整体活动性和身体功能的测量，截肢者活动性预测（AMP）作为基本假体活动性的测量，建立了CHAMP的收敛结构效度。已知的组方法构造有效性检查的差异，在高级别的移动能力与不同级别的LLL之间的SM。CHAMP评分与6MWT距离（r = 0.80，p <0.001）和AMP评分（r = 0.87，p <0.001）呈显著正相关。此外，CHAMP可以区分不同水平的LLL。研究结果支持CHAMP作为创伤性LLL SM高水平活动性的有效基于性能的评估工具。
This study examined the convergent construct validity of a new performance-based assessment instrument called the Comprehensive High-Level Activity Mobility Predictor (CHAMP) as a measure of high-level mobility in service-members (SMs) with traumatic lower-limb loss (LLL). The study was completed by 118 SMs. Convergent construct validity of the CHAMP was established using the 6-minute walk test (6MWT) as a measure of overall mobility and physical function and the Amputee Mobility Predictor (AMP) as a measure of basic prosthetic mobility. The known group methods construct validity examined disparities in high-level mobility capability among SMs with different levels of LLL. The CHAMP score demonstrated a strong positive relationship between 6MWT distance (r = 0.80, p < 0.001) and AMP score (r = 0.87,p < 0.001), respectively. In addition, the CHAMP can discriminate between different levels of LLL. Study findings support the CHAMP as a valid performance-based assessment instrument of high-level mobility for SMs with traumatic LLL.
