What Do We Mean When We Say a Program is “Evidence-based”?

Researchers examine research studies to determine whether a program:

  • Demonstrated effectiveness in rigorous scientific evaluations including randomized control trials.
  • Was assessed in large studies with diverse populations or through multiple replications by independent researchers (not the developer of the model).
  • Resulted in significant and sustained effects for a minimum of 6 months, post program.

Programs that meet all three of these criteria tend to fall in the evidence-based end of the continuum.
