Methods of evaluation: issues and implications for Physical Activity Referral Schemes

In the pursuit of evidence-based practice, the common focus on controlled research within physical activity and health promotion has created a restricted view of the acceptable type of evidence on which practice should be based.

In the context of physical activity referral schemes, this article considers the implications of adhering to this narrow definition of “acceptable” evidence and the importance of recognizing alternative evaluative approaches.
