ABSTRACT
BACKGROUND:
Six percent of the Chilean population has a disability requiring assistance with daily-living-activities and 69% of these individuals are cared by direct family members. The latter are at risk of developing caregiver burden. Zarit scales are used to assess the severity of caregiver burden.AIM:
To validate the original and abbreviated Zarit scales for caregiver burden. MATERIAL ANDMETHODS:
Two groups of interviewers applied the original and abbreviated Zarit scales, along with a single subjective indicator for burden and surveys for depression, to 32 caregivers from an outpatient clinic in Melipilla, Chile. In 22 subjects, the instruments were applied again, four months laterRESULTS:
Both Zarit scales showed high correlation with the subjective indicator for burden and with depression (r =0.51 and 0.67, respectively), supporting its construct validity. The abbreviated scale had a high correlation with the original scale (r =0.92), supporting its criterion validity. It had a 100 % sensitivity 77.7%, specificity 86.6% positive predictive value and 100% negative predictive value to discriminate severe caregiver burden, using the original scale as standard. Both instruments showed high internal consistency (Cronbach alpha =0.84 and 0.87, respectively), inter-observer reliability (intraclass correlation coefficient =0.81 and 0.86, respectively) and stability reliability (Kappa test-retest =0.91 and 0.93, respectively).CONCLUSIONS:
Both original and abbreviated Zarit burden scales are valid to assess caregiver's burden in a Chilean context. The abbreviate scale Szeged particularly useful for primary care.
