Objectives: To evaluate client and agency satisfaction with a specific assertive community treatment subprogram, known as inner-city support, developed in Edmonton to target the inner-city population, and to determine the demographics and potential needs of this population. Method: Clients were administered questionnaires based on the Client Satisfaction Questionnaire and the Satisfaction With Life Scale. We also conducted a face-to-face interview. We contacted and similarly surveyed 18 community agencies. Results: The program was well received, although areas for improvements included dissemination of information and hours of operation. Clients also requested more input regarding the development of activities. Clients were predominantly male with a diagnosis of schizophrenia comorbid with substance abuse and antisocial personality disorders, a history of forensic contact, homeless, and dependent on social assistance. Conclusion: Among the population with serious and persistent mental illness, inner-city clients represent a particularly disadvantaged subpopulation that may benefit from specialized community programs.
