Objective

To synthesize evidence regarding the psychometric properties of the Brief-Balance Evaluation Systems Test (BESTest) in assessing postural controls across various populations.

Data Sources

Articles were searched in 9 databases from inception to March 2020.

Study Selection

Two reviewers independently screened titles, abstracts, and full-text articles to include studies that reported at least 1 psychometric property of the Brief-BESTest. There were no language restrictions.

Data Extraction

The 2 independent reviewers extracted data (including psychometric properties of Brief-BESTest) from the included studies. The methodological quality of the included studies was appraised by the Consensus-based Standards for the Selection of Health Status Measurement Instruments checklist, and the quality of statistical outcomes was assessed by the Terwee et al method. A best-evidence synthesis for each measurement property of the Brief-BESTest in each population was conducted.

Data Synthesis

Twenty-four studies encompassing 13 populations were included. There was moderate to strong positive evidence to support the internal consistency (Cronbach α>0.82), criterion validity (ρ≥0.73, r≥0.71), and construct validity (ρ≥0.66, r≥0.50, area under curve>0.72) of the Brief-BESTest in different populations. Moderate to strong positive evidence supported the responsiveness of the Brief-BESTest in detecting changes in postural controls of patients 4 weeks after total knee arthroplasty or patients with subacute stroke after 4-week rehabilitation. However, there was strong negative evidence for the structural validity of this scale in patients with various neurologic conditions. The evidence for the reliability of individual items and measurement errors remains unknown.

Conclusions

The Brief-BESTest is a valid (criterion- and construct-related) tool to assess postural control in multiple populations. However, further studies on the reliability of individual items and minimal clinically important difference of the Brief-BESTest are warranted before recommending it as an alternative to the BESTest and Mini-BESTest in clinical research/practice.

多人群中简要平衡评估系统测试的心理测量学特性：系统评价和荟萃分析

客观的

综合有关简要平衡评估系统测试 (BESTest) 的心理测量特性的证据，以评估不同人群的姿势控制。

数据源

从开始到 2020 年 3 月，在 9 个数据库中搜索了文章。

研究选择

两位审稿人独立筛选标题、摘要和全文文章，以纳入报告至少 1 个 Brief-BESTest 心理测量学特性的研究。没有语言限制。

数据提取

2 位独立评审员从纳入的研究中提取数据（包括 Brief-BESTest 的心理测量学特性）。纳入研究的方法学质量采用基于共识的健康状况测量工具选择标准清单评估，统计结果质量采用 Terwee 等方法评估。对每个群体中的 Brief-BESTest 的每个测量特性进行了最佳证据综合。

数据综合

纳入了涵盖 13 个人群的 24 项研究。有中等到强的积极证据支持内部一致性（Cronbach α>0.82）、标准效度（ρ≥0.73，r≥0.71）和结构效度（ρ≥0.66，r≥0.50，曲线下面积>0.72）不同人群中的Brief-BESTest。中度至强阳性证据支持 Brief-BESTest 在检测全膝关节置换术后 4 周的患者或 4 周康复后的亚急性中风患者的姿势控制变化方面的反应性。然而，有强烈的负面证据表明该量表在患有各种神经系统疾病的患者中的结构有效性。单个项目的可靠性和测量误差的证据仍然未知。

结论

Brief-BESTest 是一种有效的（与标准和结构相关的）工具，用于评估多个人群中的姿势控制。但是，在推荐将其作为临床研究/实践中 BESTest 和 Mini-BESTest 的替代品之前，需要进一步研究单个项目的可靠性和 Brief-BESTest 的最小临床重要差异。
