Characteristics of dual diagnosis patients admitted to an urban, public psychiatric hospital: an examination of individual, social, and community domains.

The study provides descriptive data on a large, diverse sample of dually diagnosed patients from an urban psychiatric inpatient setting, utilizing a comprehensive array of clinical, social and community functioning measures. The intent is to provide more useful and reliable information, particularly concerning African-Americans with a dual diagnosis in the public sector. Over a one year period, all persons admitted to a public psychiatric hospital with a DSM-III-R psychiatric diagnosis and a positive screen for substance abuse problems using clinical and structured measures (n = 486) were interviewed on the Addiction Severity Index (ASI) and other measures to assess community and social functioning, alcohol and drug use, psychiatric problems, and service histories.
