To evaluate the function component of the Short Form of the Late-Life Function and Disability Instrument (SF-LLFDI, German version) in geriatric inpatients and compare it with established performance-based and self-rated assessment tools.
Geriatric inpatient rehabilitation unit.
One hundred fifty-six geriatric rehabilitation inpatients (44 men, 112 women) with a mean age of 81.7 who were capable of walking at baseline.
Weekly assessments were performed from admission until discharge (3 weeks later) using the function component of the SF-LLFDI, the Barthel Index (BI), the Falls Efficacy Scale International (FES-I), gait characteristics, the Timed Up and Go Test, and the Short Physical Performance Battery. Baseline characteristics were measured at admission. Construct validity was evaluated using Spearman correlation coefficients, internal consistency was measured using Cronbach alpha, and sensitivity to change was estimated using standardized response means.
The SF-LLFDI did not show significant floor or ceiling effects. Internal consistency was good, with alpha (function component sub-scores) equal to 0.80 to 0.86. Convergent validity measures concerning performance-based scores were moderate to good, and correlations increased over time (correlation coefficient (r)=0.35-0.64). There was a high correlation with the FES-I (admission: r=0.61, discharge: r=0.76). Sensitivity to change was significant for all examined scores, with the BI outperforming all other instruments, although the SF-LLFDI showed better responsiveness than the BI regarding change characteristics over time.
The SF-LLFDI is a reliable and valid self-report instrument to measure functional status in geriatric rehabilitation inpatients. It improves the assessment of clinically relevant responsiveness. Further research is warranted to improve its sensitivity to change.
评估老年住院患者中晚期生活功能与残疾量表简表（SF-LLFDI，德文版）的功能成分，并将其与既定的基于表现和自评的评估工具进行比较。
老年住院康复单元。
156名老年康复住院患者（44名男性，112名女性），基线时平均年龄为81.7岁，能够行走。
从入院到出院（3周后）每周进行评估，使用SF-LLFDI的功能成分、巴氏指数（BI）、国际跌倒效能量表（FES-I）、步态特征、计时起立行走测试和简短体能状况量表。入院时测量基线特征。使用Spearman相关系数评估结构效度，使用Cronbach α测量内部一致性，并使用标准化反应均值估计对变化的敏感性。
SF-LLFDI未显示出明显的地板效应或天花板效应。内部一致性良好，α（功能成分子分数）等于0.80至0.86。基于表现分数的收敛效度测量为中等至良好，且相关性随时间增加（相关系数（r）=0.35 - 0.64）。与FES-I有高度相关性（入院时：r = 0.61，出院时：r = 0.76）。所有检查分数对变化的敏感性均显著，BI优于所有其他工具，尽管SF-LLFDI在随时间变化特征方面显示出比BI更好的反应性。
SF-LLFDI是一种可靠且有效的自评工具，用于测量老年康复住院患者的功能状态。它改善了对临床相关反应性的评估。有必要进行进一步研究以提高其对变化的敏感性。
