To test the measurement properties (reproducibility, internal consistency, ceiling and floor effects, and construct validity) of the Human Activity Profile (HAP) questionnaire in hospitalized patients.
This measurement properties study recruited one-hundred patients hospitalized for less than 48h for clinical or surgical reasons. The HAP was administered at baseline and after 48h in a test-retest design). The International Physical Activity Questionnaire (IPAQ-6) was also administered at baseline, aiming to assess the construct validity. We tested the following measurement properties: reproducibility (reliability assessed by type 2,1 intraclass correlation coefficient (ICC)); agreement by the standard error of measurement (SEM) and by the minimum detectable change with 90% confidence (MDC), internal consistency by Cronbach's alpha, construct validity using a chi-square test, and ceiling and floor effects by calculating the proportion of patients who achieved the minimum or maximum scores.
Reliability was excellent with an ICC of 0.99 (95% CI=0.98-0.99). SEM was 1.44 points (1.5% of the total score), the MDD was 3.34 points (3.5% of the total score) and the Cronbach's alpha was 0.93 (alpha if item deleted ranging from 0.94 to 0.94). An association was observed between patients classified by HAP and by IPAQ-6 (χ=3.38; p=0.18). Ceiling or floor effects were not observed.
The HAP shows adequate measurement properties for the assessment of the physical activity/inactivity level in hospitalized patients.
测试住院患者人体活动概况问卷（HAP）的测量特性（可重复性、内部一致性、天花板和地板效应以及结构有效性）。
这项测量特性研究招募了 100 名因临床或外科原因住院时间少于 48 小时的患者。采用测试-再测试设计，在基线和 48 小时后对 HAP 进行了评估。同时在基线时还进行了国际体力活动问卷（IPAQ-6）的评估，旨在评估结构有效性。我们测试了以下测量特性：可重复性（通过 2 型、1 类内部一致性相关系数（ICC）评估可靠性）；通过测量标准误差（SEM）和 90%置信区间最小可检测变化（MDC）评估一致性；通过 Cronbach 的 alpha 评估内部一致性；通过卡方检验评估结构有效性；通过计算达到最低或最高得分的患者比例评估天花板和地板效应。
可靠性极好，ICC 为 0.99（95%置信区间=0.98-0.99）。SEM 为 1.44 分（总得分的 1.5%），MDD 为 3.34 分（总得分的 3.5%），Cronbach 的 alpha 为 0.93（如果删除项目，alpha 值在 0.94 到 0.94 之间）。HAP 和 IPAQ-6 分类的患者之间存在关联（χ=3.38；p=0.18）。未观察到天花板或地板效应。
HAP 显示出足够的测量特性，可用于评估住院患者的体力活动/不活动水平。
