Objective: The Zarit Burden Interview (ZBI) has been widely used to assess caregiver’s burden. Research investigating the Thai version of the ZBI is few. The study aimed to examine the psychometric properties of both the full length (ZBI-22) and short versions (ZBI-12) using Rasch analysis among a sample of Alzheimer’s disease caregivers.
Results: The ZBI-22 fitted the Rasch measurement model regarding unidimensionality but not for ZBI-12. Five items from ZBI-22, and two items from ZBI-12 were shown to be misfitting items. The model of ZBI-12 was improved when item “should do more” and “could do a better job caring” were removed. Reliability was good for both forms of the ZBI (a = 0.86 - 0.92). Significant correlations were found with caregiver’s perceived stress and caregiver's depression. Significant correlation with subscales of anxiety/depression, pain and mobility were indicative of discriminant validity but not with self-care and usual activity (p > 0.05). To conclude, the Thai version ZBI was supported for the reliability and validity in both the full length and 12 short forms among Alzheimer’s disease caregivers; however, some misfitting items of the ZBI undermined the unidimensionality of the scale, and need revision.
