A New Graphical Tool to Collect Ego-Centered Network Data


GENSI is available in Javascript source code and can be downloaded here.
The source code as been cleaned and commented throughout. We decided to publish the Javascript source code so that GENSI can easily be implemented as a short ego-centered network module in existing online surveys. (Also, we did not have funding to develop a graphical user interface.)
If you do not have experience with programming in Javascript, consider one of the other available software package we discuss in our publication (see below).



You can take a demo survey using GENSI here.

This movie shows a short version of the new tool to collect ego-centered network data in online surveys. Respondents first complete the network generator question by entering the names of people in their social network. Any kind of name generator can be used here. Subsequently, respondents are asked questions about each person in their social network. They can answer questions by clicking on the names of their network contacts or by dragging and dropping the names into answer categories. Also traditional survey questions can be asked about each network contact separately.
