State Treatment Needs Assessment Project (STNAP) Round I Studies

The Maine Office of Substance Abuse (OSA), part of the Maine Department of Health and Human Services, in partnership with Research Triangle Institute (RTI), conducted a series of studies designed to estimate the number of persons with substance use disorders in Maine. This project was funded through the Center for Substance Abuse Treatment (CSAT), a division of the federal Substance Abuse and Mental Health Services Administration (SAMHSA) and allowed the State of Maine, for the first time ever, to develop comprehensive, population-based estimates of need for alcohol and drug treatment services.

The first six studies, ("Round I") were Alcohol and Other Drug Household Telephone Study, Arrestee Study, School-Aged Population Study, Social Indicators Study, Assessment of the Current Treatment System Study, and Integrative Study.

Alcohol and Other Drug Household Telephone Study

More than 4,000 telephone interviews were conducted for the Household Survey in 1997. This provided data on the prevalence of substance use and need for treatment among Maine adults.

Arrestee Study

Data collection for the Arrestee Study took place in 1997 and involved over 400 interviews of new arrestees from the Cumberland and Penobscot County Jails. The prevalence of substance use and other high-risk behaviors among adult arrestees was estimated. Perceived need for and barriers to treatment were also examined.

School-aged Population

Secondary data analyses were conducted using existing surveys for the School-aged Population Study. The study used synthetic estimation to simulate the number of Maine adolescents, aged 12-17, in each county who were at risk for or in need of substance abuse treatment or intervention.

Social Indicator Study

The Social Indicator Study used archival social indicators to estimate treatment needs. This study generated estimates of treatment need for each county in the State.

Assessment of the Current Treatment System

This study was intended to determine the capacity of the formal treatment system in Miane and its ability to meet current demand for services.

Integrative Study

The purpose of this study was to integrate the information obtained from the studies in Round I into a useful framework for assessing treatment needs both now and in the future.
