HZA has worked extensively in substance abuse prevention and program development both as an evaluator and as a provider of technical assistance. Intersecting with its Public Health mission, HZA has also provided data support for many years to the State Epidemiological Outcomes Workgroup in Maine, where one of the major foci is substance abuse indicators. Evaluations have encompassed community based programs as well as specialized drug courts. Process evaluation, outcome evaluation, consumer satisfaction, fidelity assessments and cost benefit analyses have been included. To obtain consumer feedback HZA staff have interviewed many high risk populations such as opiate users, methadone patients, drug court participants and youth with a history of substance abuse. HZA follows Institutional Review Board protocols as warranted.
