目的：鉴于未来几年痴呆症患病率预计将呈指数级增长，照顾者负担的测量在老年学研究和临床实践中已变得普遍。Zarit负担访谈(BI)已成为使用最广泛的负担衡量标准。目前的研究考察了对该量表的12个条目的简略版本的反应的心理测量学特性。设计和方法：数据来源于一项关于痴呆症发病率和护理模式的全国性流行病学研究(N=1095)。在最初招募(n=770)5年后，对幸存的制度化和社区居住指数对象的非正式照顾者进行了面谈。结果：探索性因素分析和验证性因素分析的结果都支持对这个简化的量表的反应的双因素结构。在控制了人口统计学变量、痴呆症疾病特征和基线抑郁症状之后，对这一简短的BI的反应在时间2提供了对抑郁症状的预测的显著增加(R-2=.24，p<；.01)，而完全BI的其余10个项目没有提供额外的方差2(deltar(2)=0，ns)。含义：本研究的结果与照顾者负担的理论和操作定义相关。考虑到为这项研究招募的照顾者的代表性和国家构成，可以更有信心地概括研究结果。
Purpose: Given the exponential increase in dementia prevalence anticipated in the coming years, measurement of caregiver burden has become common in gerontological research and clinical practice. The Zarit Burden Interview (BI) has emerged as the most widely utilized burden measure. The current study examines the psychometric properties of responses to an abridged, 12-item version of this scale. Design and Methods: Data were derived from a national epidemiological study of dementia incidence and patterns of care (N = 1,095). Informal caregivers of surviving institutionalized and community-dwelling index subjects were interviewed 5 years subsequent to initial recruitment (n = 770). Results: Results of both the exploratory and confirmatory factor analyses support a two-factor structure of responses to this abridged scale. Subsequent to control for demographic variables, dementia illness features, and baseline depressive symptoms at baseline, responses to this brief BI provide a significant increase to prediction of depressive symptoms at Time 2 (R-2 = .24, p < .01) with no additional variance provided 2 by the 10 remaining items from the complete BI (DeltaR(2) = 0, ns). Implications: The results of this study are discussed relative to theory and the operational definition of caregiver burden. Findings can be generalized with greater confidence given the representative and national composition of caregivers recruited for this study.
