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

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.

More details about study results are available in the published evidence review.

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.

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.

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?

• 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.

Effectiveness Review

Analytic Framework see Figure 1 on page 289

When starting an effectiveness review, the systematic review team develops an analytic framework. The analytic framework illustrates how the intervention approach is thought to affect public health. It guides the search for evidence and may be used to summarize the evidence collected. The analytic framework often includes intermediate outcomes, potential effect modifiers, potential harms, and potential additional benefits.

The following outlines the search strategy used for reviews of these interventions to reduce alcohol-impaired driving: 0.08% Blood Alcohol Concentration (BAC) Laws; Lower BAC Laws for Young or Inexperienced Drivers; Maintaining Current Minimum Legal Drinking Age (MLDA) Laws; Mass Media Campaigns; Multicomponent Interventions with Community Mobilization; Ignition Interlocks; School-Based Programs; Designated Driver Promotion Programs; Sobriety Checkpoints (archived); Intervention Training Programs for Servers of Alcoholic Beverages (archived).

The reviews of interventions to reduce motor vehicle-related injury reflect systematic searches of multiple databases as well as reviews of reference lists and consultations with experts in the field. The team searched six computerized databases (MEDLINE, Embase, Psychlit, Sociological Abstracts, EI Compendex, and Transportation Research Information Services [TRIS]), which yielded 10,958 titles and abstracts for articles, book chapters, reports, and published papers from the Association for the Advancement of Automotive Medicine proceedings about safety belts, alcohol-impaired driving or child passenger safety. Studies were eligible for inclusion if:

• They were published from the originating date of the database through June 2000 (March 1998 for child safety seat interventions)
• They involved primary studies, not guidelines or reviews
• They were published in English
• They were relevant to the interventions selected for review
• The evaluation included a comparison to an unexposed or less-exposed population
• The evaluation measured outcomes defined by the analytic framework for the intervention

For alcohol-impaired driving reviews, supplementary searches were conducted to address specialized questions and to update searches for reviews published after 2001. The final search using the primary alcohol-impaired driving search strategy was conducted through December 2004. For the most recent review in this series, “Effectiveness of Multicomponent Programs with Community Mobilization for Reducing Alcohol-Impaired Driving,” this database was supplemented by a hand search of the “Alcohol and Other Drugs” and “Transportation” sections of the SafetlyLit injury literature update service for the period from January through June 2005.

CPSTF did not have enough evidence to determine whether the intervention is or is not effective. This does not mean that the intervention does not work, but rather that additional research is needed to determine whether or not the intervention is effective.
