ABSTRACT
Evidence-based health promotion and particularly evidence-based sexual health promotion, have become goals to which researchers, commissioners and service providers alike aspire. Over the last few years much has been written and said about the need and value of such work, but little of this seems to have been put into practice (Hart 1996, Flowers 1997). However, several key questions have emerged which foster a healthy sense of reflexive inquiry for all those involved in both researching and delivering sexual health promoting services. What kind of evaluation should be adopted? What constitutes evidence of effectiveness? Which methodologies and designs are best suited to providing such evidence?
