Figure 3 shows peak patient engagement during the preparation and early execution phases of projects, with surveys being the most common form of involvement and deliberation/organizational participation being the least common. Patient involvement tends to drop during data management portions of studies and increases for the final implementation of the study.
Deliberation/Organizational participation is likely the least used method of engagement due to the complex logistics and lengthiness of mass group organization and discussion. Furthermore, for some studies, a gross deliberation may often be deemed unnecessary as a result of little opportunity for variation in opinion about the research topic.
On the other hand, surveys are the most common form of engagement since they are easily distributed and can be compared quantitatively and unbiased. Focus groups are also more common, as they are easier to organize than massive deliberations since all contacts can likely come from the same “pool”, and usually require only few perspectives on the research topic (eg. If only a small population of homogeneously affected individuals are influenced by the outcomes of the study).
