Despite a rapid increase in studies dealing with dementia caregivers in Europe, a valid German version of the most widely used measurement of caregiver burden (Zarit Burden Interview) has not yet been published. The purpose of this study is to evaluate the psychometric properties of the German Zarit Burden Interview (G-ZBI).
Twenty-eight community-dwelling older couples with the husband suffering from dementia and the wife being the primary caregiver participated in this study. The G-ZBI and related constructs were assessed in order to test for reliability and construct validity.
The G-ZBI revealed psychometric properties comparable with those of the original instrument and empirically validated translations. Results demonstrated high internal consistency (Cronbach's alpha 0.92) and good validity due to strong correlations with caregiver life satisfaction and depression, as well as patients' dependency, neuropsychiatric symptoms, and dementia severity.
The psychometric qualities of the G-ZBI indicate that it is both a reliable and valid instrument to assess caregiver burden and to detect highly stressed individuals.
尽管欧洲有关痴呆症照顾者的研究迅速增加，但尚未发表最广泛使用的照顾者负担测量工具（Zarit 负担访谈）的有效德文版本。本研究的目的是评估德国 Zarit 负担访谈（G-ZBI）的心理测量特性。
本研究纳入了 28 对居住在社区的老年夫妇，丈夫患有痴呆症，妻子是主要照顾者。为了测试信度和结构效度，评估了 G-ZBI 及相关结构。
G-ZBI 显示出与原始工具和经验验证的翻译相当的心理测量特性。结果表明，由于与照顾者的生活满意度和抑郁、患者的依赖、神经精神症状和痴呆严重程度有很强的相关性，因此具有较高的内部一致性（Cronbach's alpha 0.92）和良好的有效性。
G-ZBI 的心理测量质量表明，它是一种可靠和有效的工具，可以评估照顾者的负担，并发现压力较大的个体。
