EgoNet™: Egocentric Network Assessment
In conjunction with Chris McCarty at the
University of Florida Survey Research Center,
MDLogix is developing the EgoNET system for assessing egocentric networks.
Create Egocentric Network Surveys
The EgoNET system includes an application based
specially modified to create surveys that collect
information about ego, alters, ego-alter
relationships, and alter-alter relationships.
Conduct Egocentric Network Interviews
Researchers use the EgoNET client to conduct
interviews and collect data. EgoNET displays
surveys created in EgoNET QBuilder in self-report
format, and also allows field staff to enter free
data gathered during interviews.
Visualize Egocentric Networks
The EgoNET client contains an embedded version of
application for network analysis and
visualization. After a subject completes a
network survey via self-report, the VisuaLyzer
displays the subject's network as a color-coded
interactive graph, showing the alter
characteristics and relationships associated with
answers to each question. The EgoNET VisuaLyzer
also calculates network measures such as node
centrality, centralization, and other sub-group
analyses. Field staff can use this information as
a basis for further exploration of the subject's network via interview.
Data can be collected by multiple researchers and
later synchronized to a central database. The
EgoNET client can also output and batch-process
summary ego-network data in SPSS format.
The EgoNET system is built on the Assessment
Architect platform, which can maintain text in
multiple languages for any instrument and all
interface elements. Spanish translations of the
EgoNET QBuilder and client applications are in progress.
The University of Florida Survey Research Center
is currently using the EgoNET system to study
network influences on the smoking behavior of immigrants in Spain.
