Results show that homeless persons with serious mental illness can remain in stable housing for periods of up to five years, supporting the premise that long-term residential stability can be enhanced by providing access to safe and affordable supportive housing.

The results of a study comparing the structure and function of the social networks of a group of first-admission schizophrenics with those of a group of multiple-admission schizophrenics are presented. Structurally, the networks of the first-admission patients are larger and more interconnected. Functionally, their networks have a greater percentage of multiplex and nondependent links. On the basis of these data, it is concluded that the most dramatic changes in social networks develop after the patient's first hospitalization. The dissolution of the patient's network is attributed to the antagonistic attitudes and reactions of those close to the patient, as well as to the patient's impaired social competence. Schizophrenia seemingly is a network crisis not only for the individual but for the network as a whole. It is suggested that active intervention at the time of the first psychotic episode may be helpful in avoiding network collapse and the patient's resultant social isolation.

Over the past decade, researchers have documented the range of needs and devised new methods for increasing our understanding of the homeless severely mentally ill population. Clinicians have developed an appreciation of the difficulty and complexity of effectively treating this population, and policymakers have become increasingly aware of the barriers to developing services and housing. In this article, the progress-to-date in research, the evolution of new service approaches, and the development of federal, state, and local policies to meet the needs of homeless mentally ill individuals are assessed. The many challenges that remain are also considered.
