The mean factor scores between 1.33 and 1.80, Standard deviation between 0.43 and 0.53; Compared with general model, there was a difference which has statistical significance(P<0.05) in 7 factors. The scores of interpersonal sensitivity were lower than general people(P=0.00).

(5) Influential factors of mental health:The factors influencing total score of SCL-90 were time burden, the acute and chronic disease status of senile dementia patients, with or without nanny/care workers, family income of caregivers for senile dementia patients.
