A local community hires a team of researchers to implement and evaluate a drug prevention program. After determining the needs of the community, the researchers suggest four successful drug prevention programs. The community selects one to implement.

The researchers further demonstrate that rates of drug use will only be affected if the community makes a more concerted effort in preventing use. The researchers' final conclusion is that the community's efforts to reduce drug use were not successful. These researchers conducted an evaluation of:
