To investigate the construct validity and test-retest reliability of the Climbing Stairs Questionnaire, a patient-reported measure of activity limitations in climbing stairs, in lower-limb amputees.
A cross-sectional study.
Outpatient department of a rehabilitation center.
Lower-limb amputees (N=172; mean +/- SD age, 65+/-12y; 71% men; 82% vascular cause) participated in the study; 33 participated in the reliability study.
Not applicable.
MAIN OUTCOME MEASURE(S): Construct validity was investigated by testing 10 hypotheses: limitations in climbing stairs according to the Climbing Stairs Questionnaire will be greater in lower-limb amputees who: (1) are older, (2) have a vascular cause of amputation, (3) have a bilateral amputation, (4) have a higher level of amputation, (5) have more comorbid conditions, (6) had their rehabilitation treatment in a nursing home, and (7) climb fewer flights of stairs. Furthermore, limitations in climbing stairs will be related positively to activity limitations according to: (8) the Locomotor Capabilities Index, (9) the Questionnaire Rising and Sitting down, and (10) the Walking Questionnaire. Construct validity was quantified by using the Mann-Whitney U test, Kruskal-Wallis test, and Spearman correlation coefficient. Test-retest reliability was assessed with a 3-week interval and quantified using the intraclass correlation coefficient (ICC).
Construct validity (8 of 10 null hypotheses not rejected) and test-retest reliability were good (ICC=.79; 95% confidence interval, .57-.90).
The Climbing Stairs Questionnaire has good construct validity and test-retest reliability in lower-limb amputees.
调查爬楼梯问卷的结构效度和重测信度，爬楼梯问卷是一种衡量下肢截肢患者爬楼梯活动受限的患者报告测量工具。
横断面研究。
康复中心的门诊。
下肢截肢患者（N=172；平均年龄 +/- 标准差，65 +/- 12 岁；71%男性；82%血管原因）参加了研究；33 人参加了可靠性研究。
不适用。
结构效度通过检验 10 个假设进行评估：根据爬楼梯问卷，下肢截肢患者在以下情况下爬楼梯的限制更大：（1）年龄较大，（2）血管原因截肢，（3）双侧截肢，（4）截肢水平较高，（5）合并症更多，（6）在养老院接受康复治疗，以及（7）爬的楼梯层数较少。此外，爬楼梯的限制将与根据以下内容活动受限呈正相关：（8）运动能力指数、（9）上下楼梯问卷和（10）步行问卷。结构效度通过 Mann-Whitney U 检验、Kruskal-Wallis 检验和 Spearman 相关系数进行量化。重测信度间隔 3 周进行评估，并通过组内相关系数（ICC）进行量化。
结构效度（10 个无效假设中有 8 个未被拒绝）和重测信度良好（ICC=.79；95%置信区间，.57-.90）。
爬楼梯问卷在下肢截肢患者中具有良好的结构效度和重测信度。
