In intervention studies, researchers often make a distinction between explanatory designs and pragmatic designs. Pragmatic designs have often decreased internal validity, but offer increased possibilities of implementation into clinical practice. Most nursing studies are pragmatic, and by analysing a study in which the purpose was to evaluate the effect of a nursing intervention, the different pragmatic and explanatory elements are discussed. It is concluded that the pragmatic elements need careful attention to enhance transferability.
