RESUMEN
Different studies have shown that caregivers of patients suffering from chronic physical or mental disorder endure a considerable burden. Authors decided to evaluate such burden on two groups of caregivers, [schizophrenic and ESRD patients], since few studies have been carried out regarding this subject in Iran. In an experimental, cross sectional, comparative, two-tier cohort study, 60 caregivers [30 of Schizophrenic and 30 of those suffering from End Stage Renal Disease], were selected as convenient groups. Demographic questionnaires and FBIS were completed for both groups and results were reviewed by SPSS software based on t test. Caregivers of Schizophrenic patients endured a heavier burden in comparison with those suffering from ESRD by a meaningful difference, [0.05%]. The results achieved from subgroups also showed that; caregivers of both groups bear almost similar economic burden. In subgroup of objective burden, the caregivers of schizophrenic patients endured more burdens in comparison with patients suffering from ESRD, with once again a meaningful difference. Moreover, in subgroup of subjective burden, the caregivers of Schizophrenic patients endured more burdens comparing to patients suffering from ESRD, however the difference was not meaningful. This study revealed that the caregivers of Schizophrenic patients experience more burdens, both objective and subjective, in comparison with patients suffering from ESRD
