Three years ago, the term positive psychology was reported at a symposium during the meeting of the Japanese Society of Psychiatry and Neurology. Until now, many studies have been reported at this symposium. For example, the introduction of Seligman's positive psychology, the application of positive psychology to cognitive behavior therapy, it association with brain science, the possibility for community medicine, and the well-being practical approach. I previously introduced the well-being practical approach, and reported its effects on education and clinical medicine. Many depressed patients were able to recover and return to work, suggesting that positive psychological tools are effective for psychiatric clinical medicine. Positive psychology originated in the United States and has developed independently. In 2015, Jeste & Palmer published a book on positive psychiatry, which suggests that positive psychology has been incorporated into psychiatry. In Japan, the Japanese Positive Health Psychology Society was founded in 2012. I therefore examined positive psychiatry that originated in the United States, and reported the differences from traditional psychiatry, its necessity, applications to treatment and prevention, and its future usage. Regarding positivity, numerous measurable objective data have been reported for positive psychosocial factors (PPSFs), such as resilience, optimism, and engagement, in the field of psychiatry. However, these research results have little influence on daily mental health care. Positive psychiatry should be evaluated in the future in Japan.
