To study the severity of mental burden and the source of stressors among caregivers forinpatients with cognitive disorders.

A total of 102 professional institutional caregivers were enrolled. The CBI, ZBI, and CSSQ questionnaire were applied . The scores of different stressors were assessed, and the count of burden caregivers was recorded according to the classification of stressors. χ²test or Fisher's test was used to compare the differences among different factor stressors.

The CBI score of caregivers was (52.5±14.4). ZBI score was (47.4±14.7); The CBI and ZBI scores of elderly caregivers were higher than those of young caregivers (P＜0.05).Among them, the composition ratio of aged high burden caregivers in CBI and ZBI was 74.51% and 70.59%, respectively; while that of young high burden caregivers was 7.84% and 6.86%, respectively. The CBI pressure of those with higher education was lower than that of those with lower education (P＜0.05), and the proportion of caregivers with high education and high burden was 15.69%, while the proportion of caregivers with low education and high burden was 66.67%. The ZBI scores of male caregivers were higher than that of female caregivers (P＜0.05),and the proportion of male and female high-burden caregivers was 39.22% and 38.24% respectively. The caregiver stressors questionnaires showed that the main stress was falling/falling out of bed, with a percentage of 72.55%(74/102). Being attacked, hiding away the medicine, sudden death, fear of infection, nausea at cleaning up patients' feces, and fear of being complained showed statistically significant differences in stress levels(P＜0.05).

The mental burden of caregivers for inpatients with cognitive disorders was high, and that of the elder caregivers was higher. The main stress is the fear of falling/falling out of bed.
