The survey is being conducted for the Rhode Island Department of Mental Health, Retardation, and Hospitals on health practices, including the use of tobacco, alcohol, and other drugs. The Department needs the results to better plan its services. The telephone numbers are scientifically randomly selected, and a person within the household is also randomly selected by a computer based on population demographics within Rhode Island. All information is kept strictly confidential and is protected by a Confedentiality Certificate issued for this purpose by the federal government. The selected respondents' participation is important for the study's validity.
Participation is completely voluntary.
