BARRETO-OSORIO, Ruth Vivian et al. Zarit Burden Interview: Psychometric Tests for Colombia. Aquichan [online]. 2015, vol.15, n.3, pp.368-380. ISSN 1657-5997.  https://doi.org/10.5294/aqui.2015.15.3.5.

Objective: This research was designed to determine the validity and reliability of the Zarit Burden Interview, specifically the 22-item Spanish version, as an instrument to measure the burden of care perceived by family caregivers of patients in Colombia with chronic diseases. Materials and Methods: A cross-sectional study of 652 family caregivers of patients with chronic diseases who reside in five regions of Colombia was conducted to establish construct validity, with a factor analysis and internal consistency reliability measured by determining the Cronbach's alpha value. Result: In terms of construct validity, the study reports the total loading, based on free association of a varimax rotation, and in the dimensions that include interpersonal burden, impact of care, and skills and expectations about care. The factor loadings pertain to the items introduced to measure each of the proposed dimensions. Conclusion: The results showed the 22-item Spanish version of the Zarit Burden Interview is an instrument that can be applied and understood easily in a Colombian population with different educational, socio-economic and cultural levels. It also proved to be valid and reliable for assessing the burden of care perceived by family caregivers of patients with chronic diseases.
