Results of empirical validation studies of six statistical models available for indirectly estimating the need for alcohol, drug abuse, and mental health services across a large geographic area are presented. Models were evaluated using Colorado Social Health Survey data for 4,745 adults from 48 subareas of Colorado. (SLD)

A cost analysis is presented for developing a training and employment (TEP) program at four methadone treatment centers in a quasi-experimental pilot study. Average annual costs for TEP per client were derived. The methodology can be used in other projects to compare standard and TEP-enhanced substance-abuse treatment. (SLD)

Six existing statistical procedures (models) for indirectly assessing the prevalence of need for alcohol, drug abuse, and mental health services across subareas of a state are described and critiqued in terms of epidemiological and statistical characteristics. Specific advantages and disadvantages are listed for each model. (SLD)
