The Interventions We’ve Identified Are Linked Below

Those found through an expert review process to meet the Congressional “Top Tier” evidence standard are denoted “Top Tier”; those found to require only one more step to meet this standard – e.g., replication of their sizeable, sustained effects in an additional well-conducted randomized controlled trial – are denoted “Near Top Tier”. The other listed interventions have been found promising by Coalition staff but have not yet been identified by the expert panel as Top Tier or Near Top Tier – in some cases, because of study limitations (such as only short-term follow-up) that indicate the need for additional testing.1

Top Tier LifeSkills Training (Middle school substance abuse prevention curriculum): Randomized controlled trials show sizable decrease in students’ substance abuse over five to six years.

Top Tier Staying Free (A low-cost smoking cessation program for hospitalized smokers who are willing to make a quit attempt) Randomized controlled trials show sizable increase in confirmed abstinence from smoking one year after patient discharge from the hospital.

Near Top Tier First Grade Classroom Prevention Program (Program that combines a classroom management strategy – the Good Behavior Game – with an enhanced academic curriculum): Randomized controlled trial shows a sizable reduction in substance use, and sizable increases in high school graduation and college enrollment rates.

Near Top Tier PROSPER (Partnership between universities and community teams to implement evidence-based programs for youth substance abuse prevention): Randomized controlled trial shows community-wide reductions in substance use over 6.5 years.

Big Brothers Big Sisters (Volunteer mentoring program for disadvantaged youth, ages 6-18): Randomized controlled trial shows sizable decrease in youths’ drug and alcohol use and violent behavior.

Pregnant Woman’s Self-Help Guide to Quit Smoking (A low-cost smoking cessation program for pregnant smokers): Randomized controlled trials show a sizable increase in the quit rate during the last four to five months of pregnancy.

Recovery Coaches (Program for substance-abusing parents who have temporarily lost custody of their children): Randomized controlled trial shows an increase in family reunifications, reduction in active foster care cases, and net savings to the state.

1 While we strive to ensure that our staff-level summaries are accurate and balanced, readers should note that they have received less scrutiny than those reviewed by the expert panel for Top Tier or Near Top Tier consideration.
