Abstract: Objective To investigate the current status of nursing burden and its influencing factors of caregivers of patients with severe mental disorders in one district in Chongqing. Methods A total of 1218 patients with severe mental disorders included in public security bank and managed by national information system of severe mental disorders were re-diagnosed and evaluated by various forms. At the same time，their educational level，family income ，guardian relationship，guardian care burden，drug compliance were investigated. Nursing burden was explored by Zarit Caregiyer Burden Interview (ZBI). The data were analyzed by multivariate stepwise regression analysis. Results The ratio of high nursing burden (score of 46.38±5.61) was 76%，and low nursing burden(score of 31.80± 5.91)was 24.0%. There were only 375 patients (30.8%) who were regularly treated with drugs. Multivariate stepwise regression analysis showed that the drug compliance， risk classification and disease category were the main factors affecting the nursing burden of patients with severe mental disorders. Conclusion The ZBI score of caregivers of patients with severe mental disorders in Chongqing is relatively high. The percentage of schizophrenia patients with high burden of care was the largest proportion. Poor drug compliance increases nursing burden. The risk burden of patients with grade 4 or above is especially obvious.
