Answer:
pretest-posttest nonequivalent groups design
Explanation:
Pretest-posttest nonequivalent groups design is a form of non equivalent group design, in which there is a separate treatment group that is given a pretest, receives a treatment, and then is given a posttest. While at the same time there is another nonequivalent control group that is given a pretest, but does not receive the treatment, and then is given a posttest.
The purpose of this non equivalent groups design, is find the level of improvement between the group that receive the treatment (whether they improve more) and the group that do not eceive the treatment.
Hence, considering the situation described in the question, where a comparison is made between one group that is given anti drug program and with the other group that is not given the anti drug program, then the right answer is PRETEST-POSTTEST NONEQUIVALENT GROUPS DESIGN.
