Motor Vehicle Injury – Alcohol-Impaired Driving: School-Based Programs – Peer Organizations


What the CPSTF Found

About The Systematic Review

The CPSTF finding is based on evidence from a systematic review of two studies (search period through December 2002).

The review was conducted on behalf of the CPSTF by scientists from CDC’s Division of Unintentional Injury Prevention with input from a team of specialists in systematic review methods and experts in research, practice and policy related to motor vehicle injury prevention.

Summary of Results

More details about study results are available in the published evidence review pdf icon [PDF - 258 KB].

The systematic review included two studies.

  • Neither study found a significant intervention effect on drunk driving or riding with drunk drivers.
  • One study reported other beneficial outcomes for the school community including stronger attitudes against drunk driving or riding with drunk drivers, increased knowledge of alternative ways to get somewhere, and increased access to alcohol-free events.

Summary of Economic Evidence

An economic review of this intervention was not conducted because CPSTF did not have enough information to determine if the intervention works.


Applicability of this intervention across different settings and populations was not assessed because CPSTF did not have enough information to determine if the intervention works.

Evidence Gaps

CPSTF identified several areas that have limited information. Additional research and evaluation could help answer the following questions and fill remaining gaps in the evidence base. (What are evidence gaps?)

  • To what extent are the outcomes of school-based education programs dependent on the following?
    • Content, delivery method, and the perceived status of the person delivering the intervention
    • Characteristics of the students
  • What effect do interventions have on alcohol-related traffic violations and crashes?
  • How can studies reduce attrition to increase power and validity?

Study Characteristics

  • The first study used a quasi-experimental time series (i.e., pre/post1/post2) design, with a concurrent comparison group, but there were implementation problems.
  • The second study used a post-only design and compare six schools with exemplary SADD programs to nearby schools of similar size and demographic that did not have SADD programs. Because schools were selected based on the strength of their already implemented SADD programs, baseline data could not be collected.
