To examine relationships between self-report and performance-based measures of physical function in ICU patients randomized to standardized rehabilitation therapy (SRT) or usual care (UC).
Physical function was assessed in 257 ICU patients using self-report (physical functioning scale of the SF-36 (SF-36 PFS)) and the functional performance inventory-short form (FPI-SF) as well as performance-based measures (Short Physical Performance Battery (SPPB)) and muscular strength (MS). Assessments were at hospital discharge, 2, 4, and 6 months.
Correlations between self-report and performance-based measures were not significantly different between the two groups. When examining the entire cohort, a significant, but weak, correlation (r = 0.286) was found between the SF-36 PFS and the SPPB. At 2 months, moderate correlations were found between self-report and performance-based measures. The SF-36 PFS and FPI were significantly correlated with the SPPB (r = 0.536 and 0.553, respectively) and muscular strength (r = 0.413 and 0.431, respectively). Similar associations were seen at 4 and 6 months in both groups.
Self-report and performance-based measures of physical function appear to assess different constructs at hospital discharge. Following recovery, these measures converge, but indicate different constructs are being assessed. As such, both self-report and performance-based measures of physical function should be used with ICU patients.
考察随机接受标准化康复治疗（SRT）或常规护理（UC）的 ICU 患者的自我报告和基于表现的身体功能测量之间的关系。
使用自我报告（SF-36 物理功能量表（SF-36 PFS））和功能表现量表-短表（FPI-SF）以及基于表现的测量（简易体能测试（SPPB））和肌肉力量（MS）评估 257 名 ICU 患者的身体功能。评估在出院时、2、4 和 6 个月时进行。
两组之间自我报告和基于表现的测量之间的相关性没有显著差异。当考察整个队列时，SF-36 PFS 和 SPPB 之间存在显著但较弱的相关性（r=0.286）。在 2 个月时，自我报告和基于表现的测量之间存在中度相关性。SF-36 PFS 和 FPI 与 SPPB（r=0.536 和 0.553）和肌肉力量（r=0.413 和 0.431）呈显著相关。在两组中，在 4 和 6 个月时也观察到了类似的关联。
身体功能的自我报告和基于表现的测量在出院时似乎评估了不同的结构。恢复后，这些测量方法趋于一致，但表明正在评估不同的结构。因此，应在 ICU 患者中同时使用自我报告和基于表现的身体功能测量方法。
