Assessing the psychometric properties of persian version of Zarit Burden interview among family caregivers of patients with multiple sclerosis

Abstract

Background Caring for patients with multiple sclerosis (MS) imposes a great burden on caregivers and affects their lives in various aspects. This study aimed to evaluate the psychometric properties of Persian version of 22-item Zarit Burden Interview (ZBI-22) among family caregivers of patients with MS. Methods This methodological study was conducted in Fars province, southern of Iran. For this purpose, 120 family caregivers were recruited to participate in the study from January to March 2022. Zarit Burden Interview (ZBI) was translated into Persian through forward–backward method. Face and content validity were assessed. Construct validity was assessed using exploratory factor analyses (EFA), and its reliability was assessed by measuring internal consistency and testretest stability. Results According to face validity, the impact scores of all items were more than 1.5. Content validity ratio and content validity index values of all 22 items were 0.64-1 and 0.82-1, respectively. The scalelevel CVI/Ave was 0.97. Based on the results of factor analysis, five factors with eigenvalues more than 1 were extracted, which altogether explained 62.62% of the total variance of ZBI score. Among 22 items, one item was deleted during EFA validity assessment. Factor loading values ranged from 0.40 to 0.88. The reliability of the scale was confirmed (total Cronbach’s alpha of the ZBI = 0.88). Moreover, testretest stability assessment revealed no significant difference between test and retest scores (P > 0.05). The intraclass correlation (ICC) for the ZBI and ICCs among its factors were 0.88 and 0.6–0.86, respectively. Conclusion The Persian version of five-factor structure ZBI can be a valid and reliable scale, and it can be used to assess caregiver burden among family caregivers of patients with MS in Iran.

Sobrecarga del cuidador, riesgo laboral en cuidadores informales de personas con discapacidad en Cuenca-Ecuador

“…La evaluación del cuidador incluye una entrevista para conocer los factores de riesgo, las condiciones en las que se brinda el cuidado y el apoyo y ayuda familiar y profesional (Serrano et al, 2018) Hay varios instrumentos que permiten diagnosticar la sobrecarga del cuidador, siendo los más utilizados el Índice de Esfuerzo del Cuidador y la Escala de Zarit que pueden ser aplicados por profesionales en el primer nivel de atención. La Escala de Zarit está compuesta de 22 preguntas que evalúan dimensiones como la calidad de vida, la habilidad para brindar los cuidados y la ayuda o apoyo social (Boluarte et al, 2022;Haghshenas et al, 2023).…”
