Zarit caregiver burden scale: Evidence of validity in Mexico
Abstract
The purpose was to obtain evidence of the validity of the Zarit Burden Scale in informal primary caregivers of children with chronic illness, in a hospital in Mexico City. The sample consisted of 252 participants. The instruments used were Zarit Burden Interview (CBI), General Health Questionnaire (GHQ-28) and the Perceived Stress Scale (PSS). The exploratory and confirmatory factor analysis of the scale resulted in three factors which explain 50% of the variance. Cronbach's alpha was .84 and the model fit well with values equal to or above 0.90. The criterion validity obtained between the GHQ-28 and the CBI, showed a value r=0.46. The construct validity was estimated correlating the PSS and the CBI, obtaining a value r=0.36.Downloads
