Perhaps more than with other aspects of health care or human service, crisis programs are shaped by their environments. The types of services a particular crisis program provides and the way in which it provides them are strongly influenced by the needs and goals of its funding sources and the organization it is a part of, as well as the characteristics of the community in which it is located. Consequently, the landscape of crisis programs is a confusing one. Domestic violence programs, emergency room psychiatric services, volunteer hotlines, mobile intervention teams, and many other types of programs count themselves among the providers of crisis services.
