The evaluation of program effects typically involves tracking program activities, effects on intermediary or environmental variables, and project outcomes. Program activities may be tracked though the use of a management information system. Effects on intermediary or environmental variables may be tracked through the use of apparent minor, intoxicated patron, and telephone or in-school surveys. Outcomes may be tracked through the use of archival data collected by police and sheriff departments, hospitals, trauma centers, discharge indexes, and county and state reporting agencies.
