I. What is social psychiatry? People may not remember social psychiatry as a concept developed by the National Institutes of Mental Health (NIMH) in the United States in the first two decades of its popularization of mental illness prevention. The doctrine was influenced by a variety of sources, and by the 1970s, the definition of “social psychiatry” was muddled, but by the middle of the 20th century, the concept was clear: “Social psychiatry is the most critical component of preventive psychiatry, focusing on the treatment of controllable psychiatric disorders caused by social or environmental factors. environmental factors”, which is why Kennedy suggested that “adverse environmental factors” were associated with mental illness. These factors include sexual promiscuity, poor housing, violence, and substance abuse. Second, the importance of prevention for the treatment of mental illness In view of the increase in the number of people affected by mental illness, long treatment courses, medical costs and other issues, the United States President John F. Kennedy on February 5, 1963 called for a “new approach” to mental illness “war”, “to find mental defects”, “to find mental defects”, “to find mental defects”, “to find mental defects”, “to find mental defects”, “to find mental defects”. On February 5, 1963, President John F. Kennedy called for a “new approach” to “declare war” on mental illness, “to find the cause of mental defects and to make every effort to eliminate them”, when “prevention is better than cure”. In fact, Kennedy’s team aimed to eliminate “bad environmental factors”. Kennedy’s thinking seems strange to most people today, because when it comes to mental illness, people think more about treatment, and researchers focus more on the origins of the disease, while prevention seems less important. In fact, prevention has become central to mental health care and mental illnesses are considered preventable. Modern scholars are increasingly focusing on the impact of environmental factors on mental health, while at the same time, more and more institutions are focusing on population mental health, behavioral guidelines for children, and standardized treatment for patients with a history of mental illness, initiatives that place the prevention of mental illness at the forefront of psychiatric practice and public mental health policy. In the United States, the emphasis on mental illness prevention strategies dates back to the period following the victory in World War II. Researchers at the time found that they had underestimated the number of people who developed mental illness after the war, and that cumbersome, expensive, and time-consuming treatment of mental illnesses caused clinicians to worry that “they were simply not able to provide timely care for their patients. As a result, the academic community began to turn its attention to prevention, with NIMH as the lead agency. By the late 1960s, the interdisciplinary nature of “social psychiatry” was becoming more apparent, and with it a growing body of “social psychiatry” research. Regardless of the validity of the results of these studies, this trend led to the advancement of preventive treatment of mental illnesses, and for a time “social psychiatry” was at its peak. After that, “social psychiatry” rapidly declined for various reasons, and its principle of “prevention first” was not realized. The U.S. government also deviated from its original intent and instead invested more resources in the treatment of mental illness. “Social psychiatry may have exaggerated the relationship between social and environmental factors and mental illness, but the doctrine emphasized the importance of prevention in the treatment of mental illness, and it is worthwhile for us to reflect on its use.
