Glossary

The quality of the study is moderate, meaning we can be somewhat confident in the study findings. However, factors other than the program examined could have influenced the study findings, and the study might not have fully accounted for those factors. We assign this rating to findings from randomized controlled trial studies that, because of flaws in the study (for example, high sample attrition), do not meet the criteria for the high rating but satisfy other design criteria. We also assign the moderate rating to study findings from well-executed quasi-experimental design studies.
