This case illustrates how a mixed-methods approach facilitates the study of social interactions at the individual level.

This case shows how to collect these data in an approach with pragmatic strategies that use primary and secondary research jointly. Specifically, it illustrates the collection of the data of various ascribed social relationships using interviews and pre-existing documents and the data of adoption behavior using questionnaire and historical records
