Title: Promoting the Use of Evidencebased Prevention


1
Promoting the Use of Evidence-based Prevention
  • Application in the Real World

Brian Bumbarger Prosper Statewide Meeting May 2009
2
Objectives
  • Understand the definition of evidence-based
  • Become a more informed consumer of information
  • Become an ambassador for EBP
  • Establish specific criteria for making (and
    defending) prevention programming choices in
    local communities

3
Many Sources for EBP
  • Blueprints for Violence Prevention
  • www.colorado.edu/cspv/blueprints
  • OJJDP Model Programs Guide
  • www.dsgonline.com/mpg2.5/mpg_index.htm
  • Helping Americas Youth Program Tool
  • www.helpingamericasyouth.gov/programtool.cfm
  • Guide to Community Preventive Services
  • www.thecommunityguide.org
  • Promising Practices Network
  • www.promisingpractices.net
  • Social Programs that Work
  • www.evidencebasedprograms.org
  • A Google search on Evidence Based Programs
    returned over 57 million hits

Why Evidence-based programs?
  • Funding may require EPB
  • More effective use of scarce resources
    (efficiency)
  • More confidence that what we do will make a
    difference (accountability)
  • Take advantage of existing expertise (prevention
    science)
  • Why reinvent the wheel?
  • Programs without evidence may actually be harmful

5
The Changing Lingo
  • Best Practices
  • Promising Approaches
  • Research-based
  • Science-based
  • Evidence-based
  • Model Programs
  • Blueprints

6
Whats the Difference?
  • Best Practices
  • Weve done it and we like it
  • Promising Approaches
  • We really think this will workbut we need time
    to prove it
  • Research-based
  • This intervention is based on a sound
    theoretical foundation
  • Evidence-based
  • This intervention has been tested and shown to
    work

7
Evidence-based Programs
  • Theoretically sound interventions that have been
    evaluated using a well-designed study (randomized
    controlled trial or strong quasi-experimental
    design) and have demonstrated significant
    improvements in the targeted outcome(s).
  • Evidence is strengthened by independent
    replication and sustained benefits.

8
Simple pre-post comparison
Prevention Program
We can compare the difference between pre-test
and post-test But
  • What if something else caused the change?
  • If the post-test isnt better, does that mean
    the program didnt work?
  • What would have happened in the absence of the
    program?
  • Are these kids representative of all kids?

All Model Programs are not Equal
  • Relevance of the conceptual model (theory of
    change)
  • Quantity and quality of evidence
  • Generalizability of evidence
  • Economic feasibility
  • Local fit
  • Breadth of impact
  • TA and training infrastructure
  • Peer network
  • Sustainability

11
Questions to Ask
  • How strong is the evidence?
  • Do we need it?
  • What are the other options?
  • Does the evidence apply to our population?
  • Is it worth the investment, and can we afford it?
  • Can we assemble the necessary resources and
    stakeholders?
  • Will our community find it acceptable?
  • How broad might the impact be?
  • Can the developer support our site?
  • Do we know others who have used it?
  • What will it take to sustain it?
