To analyze the internal consistency, reliability and measurement error of assessment measures for body structure and function (postural balance, muscle strength, cardiorespiratory function and physical fitness), activity (walking and mobility) and participation (quality of life and social reintegration) outcomes for use on pre-frail and frail older adults.
Searches were performed in six databases (Medline, Embase, ScienceDirect, Web of Science, The Cochrane Library and Lilacs) and reproducibility studies were included. Cronbach's alpha and the classification proposed by Terwee et al. (2007) were used for the interpretation of internal consistency. The intraclass correlation coefficient (ICC) and the Munro classification were used for the determination of reliability. The standard error of measurement (SEM), minimal detectable change (MDC) as well as percentages of error (SEM%) and change (MDC%) were calculated. Methodological quality of the studies was appraised using Boxes 4, 6 and 7 of the COSMIN Risk of Bias checklist.
Six studies were included in the present systematic review, with a total of 835 (82.4 years; 582 women and 253 men) pre-frail and frail older adults analyzed. Seven measures were identified for the assessment of body structure and function, activity and participation outcomes (Hierarchical Assessment of Balance and Mobility, Self-Assessment of Physical Fitness, Sarcopenia Quality of Life, Reintegration to Normal Living Index, Two-Minute Walking test, Six-Minute Walking test and Ten-Meter Walking test). The following measurement properties were identified: internal consistency = 0.84 (mean Cronbach's alpha); reliability = 0.87 (mean ICC); SEM range = 0.06 to 10.10; MDC range = 0.13 to 28.10; SEM% range = 5.2 % to 9.5 %; and MDC% range = 10.7 % to 28.5 %.
The present systematic review found adequate internal consistency, high reliability and an acceptable measurement error for assessment measures of body structure and function, activity and participation outcomes for use on pre-frail and frail older adults.
分析用于脆弱前期和脆弱老年人身体结构与功能（姿势平衡、肌肉力量、心肺功能和身体素质）、活动（行走和移动能力）及参与（生活质量和社会重新融入）结局评估指标的内部一致性、可靠性和测量误差。
在六个数据库（Medline、Embase、ScienceDirect、Web of Science、Cochrane图书馆和Lilacs）中进行检索，并纳入可重复性研究。采用Cronbach's α系数以及Terwee等人（2007年）提出的分类方法来解释内部一致性。使用组内相关系数（ICC）和Munro分类法来确定可靠性。计算测量标准误（SEM）、最小可检测变化（MDC）以及误差百分比（SEM%）和变化百分比（MDC%）。使用COSMIN偏倚风险检查表的第4、6和7项对研究的方法学质量进行评估。
本系统评价纳入了六项研究，共分析了835名（平均年龄82.4岁；582名女性和253名男性）脆弱前期和脆弱老年人。确定了七项用于评估身体结构与功能、活动及参与结局的指标（平衡与移动能力分级评估、身体素质自我评估、肌肉减少症生活质量、恢复正常生活指数、两分钟步行试验、六分钟步行试验和十米步行试验）。确定了以下测量特性：内部一致性=0.84（Cronbach's α系数均值）；可靠性=0.87（ICC均值）；SEM范围为0.06至10.
