Confirmatory Factor Analysis of a Brief Version of the Zarit Burden Interview in Black and White Dementia Caregivers
Flynn Longmire, Crystal V.; Knight, Bob G.
Gerontologist, v51 n4 p453-462 Aug 2011
Purpose of the study: 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. Design and Methods: Distribution, reliability, and confirmatory factor analyses were performed with a 14-item three-factor ZBI factor model in a sample of 175 Black and 225 White caregivers of family members with dementia. Results: The 14 ZBI items were reliable and fairly normally distributed for both groups. The three-factor model fits the data and was invariant across the Black and White caregivers for number of factors, factor loadings, and factor covariances. Implications: These findings contribute to the literature on the factor structure of the ZBI and provide new data on the invariance of the ZBI across two racial/ethnic groups of caregivers. This study provides support for the validity of findings that compare the burden scores of Black and White caregivers in studies utilizing the ZBI. The 14-item version also offers a more parsimonious way to measure burden in clinical settings, potentially increasing screening opportunities when caregiver contact time is limited.
