A comparison of psychometric properties of two common measures of caregiving burden: The family burden interview schedule (FBIS-24) and the Zarit caregiver burden interview (ZBI-22)

Purpose: The Family Burden Interview Schedule (FBIS-24) and the Zarit Caregiver Burden Interview (ZBI-22) are among the most widely used measures for assessing caregiving burden, but their psychometric performances have not been compared in the same study of caregivers of people living with schizophrenia (PLS). This is important because the measures assess overlapping constructs-the FBIS-24 assesses objective burden (e.g., completion of manual tasks) and the ZBI-22 assesses subjective burden (e.g., perceived distress, stigma). This study seeks to fill this gap by comparing the reliability and validity of the FBIS-24 and the ZBI-22 in a Chinese community sample of caregivers of PLS. Methods: A Cross-sectional stud was conducted in a community-based mental health service program in Central South part of China. A total of 327 primary family caregivers of PLS completed face-to-face interviews of the FBIS-24, the ZBI-22, the Patient Health Questionnaire (PHQ-9), the Generalized Anxiety Disorder Scale (GAD-7), and the Family Adaptation, Partnership, Growth, Affection and Resolve Index scale (APGAR), and PLS were assessed using the Global Assessment of Function scale (GAF). Results: Our findings show that both the FBIS-24 and ZBI-22 have comparable psychometric performance in terms of the internal consistency, convergent validity and known group's validity. Conclusion: Both the FBIS-24 and the ZBI-22 are psychometrically sound measures of caregiving burden but the choice of which measure to use will depend on the research question.
