Sources of income among homeless adults with major mental disorders or substance use disorders

Objective: The study documented sources and amounts of income among homeless adults with major mental or substance use disorders. It examined whether income varied by diagnostic group and whether those who received case management would be more likely to have income. Methods: A total of 564 homeless adults from a countywide probability sample completed structured interviews. Based on DSM-III-R criteria, respondents were divided into four groups-those with current major mental disorders, substance use disorders, dual disorders, and no disorders. Income from entitlement benefits, formal- sector employment, informal-sector employment, and other sources was documented by group. Logistic regression analysis was used to examine relationships between income sources, case management, and diagnostic groups. Results: Although informal-sector income was the most common income source, it provided the fewest median dollars per month ($42). Entitlement benefits provided the most monthly income ($340) and was the second most common source. Respondents with major mental disorders, substance use disorders, or dual disorders were no less likely than those with no disorders to report income from entitlement benefits or formal-sector employment. Among those with major mental disorders, substance use disorders, or dual disorders, respondents who had recent case management were four to nine times more likely to report entitlement income. Conclusions: The results support other research and anecdotal findings on the importance of case management in obtaining entitlement income among homeless adults with major mental or substance use disorders.
