The aim of this chapter is to provide guidelines for designing a study and to stress that design issues are closely related to the aim of the study and the available options for doing the study. Observational epidemiology rely on information in populations, generated by causal relations and conditions related to data collection and sampling. A trial provides the opportunity to shape this experience in a way that will reduce sources of bias seen in observational research. Classification of designs and the most frequent method problems are presented and discussed. Ten key lectures are listed as well as a set of key references.

Keywords:   study, design, observational research, causal mechanisms, bias
