Early use of alcohol, tobacco, and other drugs threatens the physical and mental well-being of students and continued use negatively affects many areas of development. An internet-based, tailored intervention based on the Transtheoretical Model of Behavior Change was delivered to middle school students to reduce alcohol, tobacco, and other drug use. This internet-based approach requires very little faculty and staff time, which is efficient given curricular demands.
Twenty-two middle schools in the United States were matched and randomly assigned to either the intervention or control conditions (N = 1,590) students who had ever used substances. Participants received one pre-test assessment, three thirty-minute intervention sessions over three months, and two post-test assessments (3 and 14 months after pre-test, respectively).
Random effects logistic models showed significant treatment effects for the intervention group when compared to the control group at the 3-month post-test.
This program has the potential to be applied as stand-alone practice or as part of more intensive interventions to promote substance use cessation.
