Prevention of Alcohol Use in Older Teens: A Randomized Trial of an Online Family Prevention Program

March 2019

A recently released publication in the journal Psychology of Addictive Behaviors, “Prevention of Alcohol Use in Older Teens: A Randomized Trial of an Online Family Prevention Program” reveals successful results for an on-line, family-based prevention program, Smart Choices 4 Teens, which is designed to reduce alcohol use among 16 and 17-year old teens.

To test whether Smart Choices 4 Teens works, 411 families were randomly assigned to either the program or to a control condition. Based on data collected 6 months after the intervention, Smart Choices 4 Teens decreased alcohol use and alcohol-related problems for teens. Using a Dosage model analyses that reflects whether the amount of the program completed is related to outcomes, the following outcomes were significant at the 6-month follow-up:

  • Teens drank fewer days and less alcohol over the last six months.
  • Teens drank fewer days and less alcohol over the last 30 days.
  • Teens reported less drunkenness and less binge-drinking during the past 30 days.
  • Teens reported less parent and teen communication that it is “ok” to drink.
  • Higher program dosage was related to more parent and teen-reported communication about social host laws.

After 12 months, the following outcomes were related to the amount of program completed:

  • Teens drank fewer days and consumed less alcohol over the past 30 days.
  • Teens consumed less alcohol over the past 6 months,
  • Teens reported less drunkenness over the past 6 months.

Using another statistical model referred to as Intention-to-Treat (comparing all families in the experimental group to all families in the control group, regardless of whether the families in the experimental group initiated the program), statistically significant outcomes were found for the Smart Choices 4 Teens at the 6-month follow-up:

  • Teens in the experimental group reported fewer friends who had been drunk.
  • Parents in the experimental group reported more communication about social host laws.

These results indicate that this web-based delivery of a parent-teen prevention program,  Smart Choices 4 Teens, reduces teen alcohol use and risk factors for teen alcohol use. Engaging families in program completion is particularly important in a family-based prevention strategy, and this program supported both parents and teens engaging in the materials with off-line guided family discussions.  Given the limited alcohol prevention programs available for older teens, Smart Choices 4 Teens fills an important gap in the health promotion efforts directed toward teenage alcohol use.  

Says lead author, Dr. Hilary Byrnes of the Prevention Research Center: “Findings indicate that Smart Choices 4 Teens works and show that a family-based web approach to alcohol prevention is relevant for older teens. Future research should focus on strategies to encourage families to engage in and complete prevention programming.”
