					Assessing the quality of evidence in
evidence-based policy: why, how and when?
Author(s):

Pawson, Ray

Abstract:

Interest in the issue of research quality is at an all time high, driven in part by the
evidence based policy agenda. The systematic review is the chosen instrument for
distinguishing between high and low quality evidence, and a key step in the method
is the establishment of inclusion criteria for identifying those studies on which most
reliance should be placed. Examines recent yardsticks developed for this purpose,
concluding that the drive to develop formal checklists of quality indicators is
premature, and that appraising quality is not, and cannot be, a technical preliminary
to research synthesis. Open and critical debate on the interpretation of research
findings remains the surest way to establish and maintain investigatory standards.
