Abstract

Objectives

The Zarit Burden Interview (ZBI) is one of the most widely used instruments for assessing caregiver burden. One of the most used short scales of the ZBI is the 7-item version. The aim of the study was to conduct a systematic review and generalization meta-analysis of the reliability and validity of the scores of the short version ZBI-7 items to determine whether they provide average values that justify their application and, secondly, to identify the characteristics of the studies that could explain the heterogeneity among the estimates.

Methods

Forty-eight articles were identified that applied the short version of the ZBI-7, of which only 14 reported a reliability coefficient and 7 reported sensitivity, specificity and predictive values. A random effects model was applied in the statistical analyses.

Results

The average Cronbach's alpha coefficient was 0.866 (95 % CI [0.835, 0.891], k = 15), with high heterogeneity (I² = 86.4 %). Mean sensitivity was 98.6 % (95 % CI [70.0 %–95.3 %], k = 3), mean specificity was 87.4 % (95 % CI [93.6 %–99.7 %], k = 3), mean positive predictive value was 93.7 % (95 % CI [81.3 %–98.1 %], k = 3), mean negative predictive value was 97.3 % (95 % CI [87.5, 99.4], k = 3).

Conclusions

According to psychometric theory, the ZBI-7 can be considered reliable and valid for exploratory purposes in both research and clinical practice.

短版Zarit Burden Interview-7评分的内部一致性、敏感性、特异性和预测价值：系统评价和泛化荟萃分析

目的：Zarit负担访谈（ZBI）是评估照顾者负担最广泛使用的工具之一。ZBI最常用的短量表之一是7项版本。本研究的目的是对短版ZBI-7项目得分的信度和效度进行系统回顾和综合元分析，以确定它们是否提供了证明其应用合理性的平均值，其次，确定研究的特征，可以解释估计之间的异质性。方法：选取48篇采用短版ZBI-7的文章，其中仅有14篇报道了信度系数，7篇报道了敏感性、特异性和预测值。统计分析采用随机效应模型。结果：平均Cronbach's alpha系数为0.866(95 % CI [0.835, 0.891], k = 15)，异质性较高（I2 = 86.4 %）。意思是灵敏度98.6 %(95 % CI(70.0 % -95.3 %),k = 3),意思是特异性87.4 %(95 % CI(93.6 % -99.7 %),k = 3),平均阳性预测值为93.7 %(95 % CI(81.3 % -98.1 %),k = 3),意思是阴性预测值为97.3 %(95 % CI [87.5, 99.4], k = 3)。结论：根据心理测量学理论，ZBI-7量表在研究和临床实践中都具有一定的可靠性和有效性。
