To provide evidence for the validity and reliability of a new outcome measure of balance, the Community Balance and Mobility Scale, developed for the ambulatory individual with traumatic brain injury.
A validity and reliability study.
Acute care, in- and outpatient rehabilitation and day hospital settings.
Two convenience samples (n=36, 32) of ambulatory patients with traumatic brain injury.
The content and construct validity, test-retest, inter- and intra-rater reliability and internal consistency of the Community Balance and Mobility Scale.
Content validity was demonstrated by the involvement of patients with traumatic brain injury (n=7) and clinicians (n=17) in the process of item generation and by physical therapists' ratings of item relevance. Further support is the correlation of the Community Balance and Mobility Scale scores with physical therapists' global balance ratings of the patient (r=0.62). Construct validity was supported by the ability of the measure to differentiate between patients along the continuum of care and also by comparisons with maximal walking velocity (r=0.64). Patients who scored greater than or less than 50 on the balance measure demonstrated significantly different Community Integration Questionnaire scores (P=0.004). The Community Balance and Mobility Scale demonstrated intraclass correlation coefficients (ICCs) of 0.977, 0.977, 0.975 and Cronbach's alpha of 0.96 for intra-, inter-, test-retest reliability and internal consistency, respectively.
The Community Balance and Mobility Scale is a valid and reliable outcome measure for the ambulatory individual with traumatic brain injury.
为一种新的平衡功能评估工具——社区平衡与移动性量表的有效性和可靠性提供证据，该量表是为脑外伤后可独立行走的个体开发的。
一项有效性和可靠性研究。
急症护理、住院及门诊康复和日间医院环境。
两组方便样本，分别为 36 名和 32 名脑外伤后可独立行走的患者。
社区平衡与移动性量表的内容效度、结构效度、重测信度、评分者间信度与评分者内信度以及内部一致性。
脑外伤患者（n = 7）和临床医生（n = 17）参与条目生成过程以及物理治疗师对条目的相关性评分证明了内容效度。进一步的支持证据是社区平衡与移动性量表得分与物理治疗师对患者的整体平衡评分之间的相关性（r = 0.62）。该测量工具能够区分不同护理阶段的患者，并且与最大步行速度具有相关性（r = 0.64），这支持了结构效度。在平衡测量中得分高于或低于 50 的患者，其社区融合问卷得分存在显著差异（P = 0.004）。社区平衡与移动性量表的组内相关系数（ICC）在评分者内信度、评分者间信度、重测信度和内部一致性方面分别为 0.977、0.977、0.975，Cronbach's α 系数为 0.96。
社区平衡与移动性量表是评估脑外伤后可独立行走个体的有效且可靠的评估工具。
