Psychometric evaluation of the Turkish version of the Zarit Burden Interview in family caregivers of inpatients in medical and surgical clinics.

The aim of this study was to adapt the Zarit Burden Interview (ZBI) to family caregivers of inpatients in medical and surgical clinics to assess the validity and reliability of the Turkish version. The study design was descriptive and methodological. A total of 223 family caregivers providing care to patients for at least 1 week in clinics were selected through convenience sampling. Data were collected using the Turkish translation of the ZBI. The psychometric testing of the adapted instrument was carried out to establish internal consistency, interitem correlation, and construct validity. The content validity procedure resulted in a final scale comprising 18 items. Cronbach's alpha was .82. Factor analysis yielded one factor. The Turkish version of the ZBI adapted to the clinics can be used as a one-factor tool.
