The aim of the study was to estimate the reliability, validity and internal structure of the Polish version of the Zarit Burden Interview scale (ZBI).

The participants in the study were 504 Polish family caregivers (spouses, parents, children and other family members) of chronically ill patients. The Burnout Scale version for caregivers (SWS) and the Resilience Assessment Questionnaire (KOP-26) were used.

The Polish version of the Zarit Burden Interview demonstrated good psychometric properties. Confirmative factor analysis confirmed the presence of a three-factor second-order structure, the model proved to be quite well suited to the data (CFI = 0.941; TLI = 0.931; SRMR = 0.045; RMSEA = 0.061). Also, the results of the theoretical validity analysis proved to be satisfactory. Cronbach’s α coefficient for the general result was 0.91; for individual subscales: “Negative image of the patient” – 0.85, “Frustration” – 0.82 and “Losses” – 0.85.

The Polish version of the ZBI scale can be used as a reliable and accurate diagnostic tool to measure the burden among carers of chronically ill people. Qualitative analysis of the response content also allows to identify areas requiring the implementation of activities in the field of psychological support for the surveyed caregivers.
