Abstract:These days, aging population has become a global issue, and the situation in China is particularly grave, which leads to increasing attention from the government regarding the psychological health of the elderly. The Chinese government demands the relevant studies based on national conditions, focusing on the psychological problems and services for the elderly. The findings from these studies could help the government to cope with aging population, construct a social service system for the elderly, and develop pension service industry. Based on a large scale survey in Jiangsu Province from 2012 to 2014, the happiness of the elderly is relatively high and is affected by their age, marriage status, living condition, children's situation, income level, and so on. Meanwhile, the elderly also experience a host of negative symptoms, including varied levels of loneliness, depression, anxiety, and paranoia. Furthermore, based on the experiences of mental health from Jiangsu Province, we described some innovative psychological services for the elderly.
