The Zarit Burden Interview (ZBI) is believed to be the most commonly used measure of caregiver burden. Originally developed more than 20 years ago for use with informal caregivers of community dwelling persons with Alzheimer disease, it has subsequently been administered to a diverse range of patient populations, formal or paid caregivers, and translated into numerous languages. Given that the ZBI is now used more broadly than it was initially intended and first validated, the current study applies the reliability generalization meta-analytic procedure to examine the psychometric properties of responses to the ZBI across populations. Multiple regression with categorical variables was performed to identify factors associated with error variance in ZBI reliability estimates (N=138 data points). Number of items, residence of the care recipient (community) and the Hebrew version each contributed significantly to prediction of internal consistency. These differences, however, were found to be relatively small and within accepted parameters. Generally, responses to the ZBI appear reliable across populations of caregivers and patients. Only versions of the ZBI with more or less than 22-items (nonstandard formats) reflect both statistical and meaningful differences in reliability. Where feasible, it is recommended that the 22-item version of the ZBI be used in future research and clinical practice.
Zarit负担访谈量表（ZBI）被认为是最常用的照护者负担测量工具。该量表最初于20多年前开发，用于社区中患有阿尔茨海默病患者的非正式照护者，随后被应用于各种患者群体、正式或付费照护者，并被翻译成多种语言。鉴于ZBI目前的使用范围比最初的设计和首次验证时更为广泛，本研究采用可靠性概括元分析程序来检验不同人群对ZBI回答的心理测量特性。进行了带有分类变量的多元回归分析，以确定与ZBI可靠性估计中的误差方差相关的因素（N = 138个数据点）。条目数量、受照护者的居住地点（社区）以及希伯来语版本均对内部一致性的预测有显著贡献。然而，这些差异相对较小，且在可接受的范围内。总体而言，不同人群的照护者和患者对ZBI的回答似乎是可靠的。只有条目数量多于或少于22条的ZBI版本（非标准格式）在可靠性方面体现出统计学和有意义的差异。在可行的情况下，建议在未来的研究和临床实践中使用22条目的ZBI版本。
