Emergency psychology: a mobile service for police crisis calls.

The Emergency Treatment Center, a new program of crisis intervention services, has been in operation since February 1975. This seven-day-week, twenty-four-hour-a-day program backs up ten Northern California police departments to provide help to people who are experiencing psychological emergencies such as violent family fights, suicide attempts, and severe emotional disturbance; in addition, the Center responds to any kind of crisis call involving adolescents. The population of the area served is approximately 750,000 of whom approximately 110,000 are adolescents between 10 and 17 years of age.
