McAlister's Field Experiment Was Successful in Helping Seventh-Graders Resist Peer

McAlister's field experiment was successful in helping seventh-graders resist peer pressure to smoke cigarettes. His strategy involved teaching students:

A) how to be assertive and just say "no."
B) a series of counterarguments they could use against peer pressure, such as, "I'd be a real chicken if I smoked just to impress you."
C) how to educate their peers about the tremendous health risks involved in smoking.
D) how to maintain high self-esteem, so they would be more resistant to peer pressure.
