"From the 'about this manual' section at the beginning of the book: 'This revised first edition was produced for the purposes of improving mental health knowledge and skills of the U.S. public in responding to early-stage mental illnesses and mental health crises. The course information is most relevant in situations where it becomes apparent to others that persons in their social network are developing serious mental health problems. However, the course may also provide useful information on how to assist a person who has a history of a mental disorder or longer-term mental health problems.' "--Amazon.
