The objective of this study was to assess the reliability of the Balance Scale. Subjects were chosen from a larger group of 113 elderly residents and 70 stroke patients participating in a psychometric study. Elderly residents were examined at baseline, and at 3, 6 and 9 months, and the stroke patients were evaluated at 2, 4, 6 and 12 weeks post onset. The Cronbach's alphas at each evaluation were greater than 0.83 and 0.97 for the elderly residents and stroke patients respectively, showing strong internal consistency. To assess inter-rater reliability, therapists treating 35 stroke patients were asked to administer the Balance Scale within 24 hours of the independent evaluator. Similarly, caregivers at the Residence were asked to test the elderly residents within one week of the independent evaluator. To assess intra-rater reliability, 18 residents and 6 stroke patients were assessed one week apart by the same rater. The agreement between raters was excellent (ICC = 0.98) as was the consistency within the same rater at two points in time (ICC = 0.97). The results support the use of the Balance Scale in these groups.
本研究的目的是评估平衡量表的可靠性。研究对象从参与一项心理测量研究的113名老年居民和70名中风患者的更大群体中选取。对老年居民在基线时以及在3个月、6个月和9个月时进行检查，对中风患者在发病后2周、4周、6周和12周进行评估。老年居民和中风患者在每次评估时的克朗巴哈系数分别大于0.83和0.97，显示出很强的内部一致性。为了评估评分者间信度，要求治疗35名中风患者的治疗师在独立评估者评估后的24小时内使用平衡量表进行评估。同样，要求养老院的护理人员在独立评估者评估后的一周内对老年居民进行测试。为了评估评分者内信度，由同一名评分者对18名居民和6名中风患者在相隔一周的时间进行评估。评分者之间的一致性极佳（组内相关系数=0.98），同一名评分者在两个时间点的一致性也很好（组内相关系数=0.97）。研究结果支持在这些群体中使用平衡量表。
