An experimental study is the standard method for evaluating clinical effectiveness. In such a study, a group of people exposed to an intervention is compared with another group that has not been exposed. There are a range of study designs with various advantages and disadvantages. This chapter discusses these different designs and how the most appropriate design must be chosen. It considers some of the strengths and weaknesses of randomized controlled trials and describes some other forms of experimental design used in health promotion.
