This article provides the results of the psychometric testing of the Brief Impairment Scale (BIS). The BIS is a 23-item instrument that evaluates three domains of functioning: interpersonal relations, school/work functioning, and self-care/self-fulfillment. It capitalizes on the strengths of existing global measures while addressing some of their limitations.
Cross-sectional parent respondent data from one clinical (N = 757) and two community samples (N = 1,888 and 1,132) of children ranging in age from 4 to 17 years is employed to test the reliability and validity of the BIS. Receiver operating characteristic analyses are employed to assess useful cutoff scores on the scale.
The total scale's internal consistency ranged from 0.81 to 0.88 and from 0.56 to 0.81 on the three subscales. Test-retest reliability for individual items ranged from fair to substantial in all but six items. The BIS has high convergent and concurrent validity. Receiver operator characteristic analyses suggest possible thresholds for different uses.
The BIS is psychometrically sound, useful in assessments and as an outcome measure in clinical practice and research. Its advantages over other global impairment instruments are that it is respondent based, short in administration time, and multidimensional.
本文提供了简易功能损害量表（BIS）的心理测量学测试结果。BIS是一个包含23个条目的工具，用于评估三个功能领域：人际关系、学校/工作功能以及自我照顾/自我实现。它利用了现有综合测量方法的优势，同时解决了其中一些局限性。
采用来自一个临床样本（N = 757）以及两个社区样本（N = 1888和1132）的4至17岁儿童的横断面家长应答数据，来测试BIS的信度和效度。采用受试者工作特征分析来评估该量表上有用的临界分数。
总量表的内部一致性在0.81至0.88之间，三个子量表的内部一致性在0.56至0.81之间。除六个条目外，单个条目的重测信度从一般到较高。BIS具有较高的收敛效度和同时效度。受试者工作特征分析表明了不同用途的可能阈值。
BIS在心理测量学上是可靠的，在评估中有用，并且可作为临床实践和研究中的一项结果指标。它相对于其他综合功能损害工具的优势在于它以应答者为基础、施测时间短且具有多维性。
