OBJECTIVE: The study sought to estimate the number of programs in the
U.S. for severely mentally ill adults that used the assertive community
treatment model and to describe variations in characteristics of the
intervention across programs. METHODS: Assertive community treatment
programs identified by state mental health authorities completed a 12- item
survey. The survey included questions on caseload, composition of the
treatment team, nature of services, and structure of service provision.
RESULTS: A total of 303 of 340 programs (89 percent) identified by states
responded to the survey. More than 75 percent provided most of their
services in the field, delivered medications, included medical staff on the
assertive community treatment team, and had caseload ratios of less than 20
consumers for each provider. CONCLUSIONS: Assertive community treatment
programs have disseminated quite unevenly across 33 states, with the
highest concentrations of programs in midwestern and eastern states.
