To evaluate the reliability and validity of a new observational measure of children's procedure-related distress behaviors, the Brief Behavioral Distress Scale (BBDS), to provide clinicians with an efficient, economical alternative measure that does not depend on continuous interval coding.
Forty-eight randomly selected videotaped invasive medical procedures performed on children (ages 2 to 10 years) with chronic illness were coded with the BBDS and the Observation Scale of Behavioral Distress (OSBD). Reliability and validity analyses along with item analysis were conducted.
Total distress scores of the BBDS were highly correlated with six of seven concurrent validity measures from multiple sources (i.e., OSBD, parent ratings, two nurse ratings, child self-report, and a physiological arousal measure, heart rate) (range r =.57-.76, p <.001-.0001). A robust association was found between the BBDS distress scores and OSBD total distress scores (r =.72, p <.0001). For two concurrent validity measures, the BBDS demonstrated stronger associations than did the OSBD. Interrater reliability was high for each BBDS distress behavior category.
Based on the findings reported, the BBDS is a reliable and valid measure of children's procedure-related distress with functional utility in both research and clinical settings.
评估一种新的观察儿童与医疗程序相关的苦恼行为的测量方法——简明行为苦恼量表（BBDS）的信度和效度，为临床医生提供一种高效、经济且不依赖连续区间编码的替代测量方法。
对48例随机选取的患有慢性病的2至10岁儿童进行侵入性医疗程序的录像，用BBDS和行为苦恼观察量表（OSBD）进行编码。进行了信度和效度分析以及项目分析。
BBDS的总苦恼得分与来自多个来源的七个同时效度测量中的六个高度相关（即OSBD、家长评分、两名护士评分、儿童自我报告以及一项生理唤醒测量指标心率）（相关系数r范围为0.57 - 0.76，p < 0.001 - 0.0001）。发现BBDS苦恼得分与OSBD总苦恼得分之间存在强关联（r = 0.72，p < 0.0001）。对于两项同时效度测量，BBDS表现出比OSBD更强的关联。每个BBDS苦恼行为类别的评分者间信度都很高。
基于所报告的研究结果，BBDS是一种可靠且有效的测量儿童与医疗程序相关苦恼的方法，在研究和临床环境中均具有实用价值。
