"Self-injury" has become one of the most globally interested issues，Taiwan now has faced the aging problems and those aging related biological, psychological, and social-cultural problems，In our country, the self-injury ratio among the elderly is far ahead than those of any other age groups。The same ratio is even way higher than those of the developed countries like, Japan, American, and European countries. Thus, the issue of self-injury among the elderly is one of the most urgent problems. In this study, theories of self-injury (including Psychoanalysis Theory, Behavioral and Cognitional Theory, Ecological Systems Theory, and social aspect), and the reasons for self-injury (including physical and psychological diseases, psychological aspects, social-cultural aspects) were adapted as the background theories to analyze the issue for self-injury among the elderly. Besides that, it also examined the methods, in the aspects of public health prevention education, and diseases and health education, for preventing the self-injury in our country, and methods developed under the concept of the third degree prevention to discuss the effectiveness of these methods. The authors suggest that the government should provide practical and effective psychological health service in the policy aspect, for instance, family policy, educational policy, and social policy, and in the application aspect, for instance, in the aspect of the elderly＇s family, the aspect of the community network, the aspect of psychological health and home care service, and the aspect of spiritually caring service. In addition of providing the above services, the government should connect the services with community resources to build workable community networks to enhance the psychological-social health of the elderly people in our country.
