Confirmatory Factor Analysis of a Brief Version of the Zarit Burden Interview in Black and White Dementia Caregivers

Although the Zarit Burden Interview (ZBI) is one of the most extensively used measures in research for caregiver burden, few researchers have examined its factor structure. Furthermore, though the ZBI has also been used in cross-group comparisons of burden, there have not been studies of whether or not it measures burden equally across various groups. Therefore, this study considers the psychometric properties of a brief version of the ZBI with particular attention to its factor structure and metric equivalence across two racial groups.
