What types of evidence will you consider sufficient to determine whether an intervention outside the U.S. is effective?

For an intervention or approach to be considered effective, there should be findings from previous research that was able to attribute health or gender equity outcomes to the intervention. These studies may have been qualitative, quantitative, or mixed-methods and should have included valid and reliable measures, high quality data, and appropriate analyses. We also highly value findings from natural experiments that have taken advantage of changes in large-scale programs, policies, and practices to establish causal evidence of effects.
