Summary
The Chinese Zarit Burden Interview (CZBI) is a reliable and valid tool for assessing caregiver burden in dementia patients. This validated instrument helps understand the challenges faced by family caregivers in Taiwan.
Area of Science:
- Gerontology
- Psychometrics
- Public Health
Background:
- Dementia prevalence is rising in China, placing significant burdens on family caregivers.
- Understanding and measuring caregiver burden is crucial for developing support systems.
Purpose of the Study:
- To evaluate the reliability and validity of the Chinese version of the Zarit Burden Interview (CZBI).
- To establish a psychometrically sound instrument for assessing caregiver burden in the Chinese population.
Main Methods:
- 181 patient-caregiver dyads participated.
- Caregivers completed the CZBI, Caregiver Activity Survey (CAS), and Chinese Health Questionnaire (CHQ-12).
- Patient cognitive status was assessed using the Mini-Mental State Examination and Clinical Dementia Rating Scale.
Main Results:
- The CZBI demonstrated good overall reliability, with high internal consistency and test-retest reliability.
- Strong correlations between CZBI, CAS, and CHQ-12 scores confirmed concurrent validity.
- Factor analysis identified five factors explaining 60% of the variance.
Conclusions:
- The CZBI is a feasible and psychometrically sound instrument for measuring caregiver burden in Taiwanese dementia patients.
- This validated tool can aid in identifying and supporting caregivers experiencing significant stress.
