Expenditures of time and money by families of people with severe mental illness and substance use disorders.

Families are typically a major source of support for people with mental illness, but substance abuse places an additional burden on family relations and could reduce the amount of direct support they give. Data from families of 169 people with co-occurring mental illness and substance abuse indicate that they give a substantial amount of time and money to their relatives with dual disorders. More severe current substance abuse appeared to reduce family spending but not direct caregiving. Clients with more severe alcohol problems were more likely to live with parents than with other family members.
