This article suggests that social network concepts and methods can provide a unifying framework for social research on schizophrenia. A selective review of the literature indicates that a social network perspective is not only consistent with a range of other research approaches and findings, but may help resolve some basic and persistent methodological and conceptual problems. A theoretical model is briefly described which attributes a critical role in the onset and recurrence of schizophrenia to social network processes. Some examples are given of the potential contribution of social network variables to research and therapy in schizophrenia.

A selective review of the literature reveals some methods and instruments that show promise for the investigation of social support as a factor in the course and treatment of schizophrenia. Approaches are divided into social-psychological questionnaires, anthropological network studies, ethnographies, and clinical epidemiological investigations. Social support measures designed for the general population probably have little relevance in schizophrenia. It appears that the most useful information comes from immersion in the experience of the patients, families, and caretakers rather than from an effort to develop a measure of social support in general that would be applicable to them.
