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 servicemembers (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.
本研究检验了一种名为综合高级活动移动性预测器（CHAMP）的新型基于表现的评估工具作为衡量下肢创伤性截肢（LLL）军人（SMs）高级移动性的收敛效度。该研究由118名军人完成。使用6分钟步行试验（6MWT）作为整体移动性和身体功能的衡量指标，以及截肢者移动性预测器（AMP）作为基本假肢移动性的衡量指标，确立了CHAMP的收敛效度。已知组方法构建效度检验了不同LLL水平的军人在高级移动性能力方面的差异。CHAMP得分分别与6MWT距离（r = 0.80，p < 0.001）和AMP得分（r = 0.87，p < 0.001）呈强正相关。此外，CHAMP可以区分不同水平的LLL。研究结果支持CHAMP作为一种有效的基于表现的评估工具，用于评估患有创伤性LLL的军人的高级移动性。
