Dhand et al. (2018) have developed a quantitative social network assessment tool that captures the structure and composition of a personal network including specific persons, their relationships to each other, and their health habits. An updated version of the instrument called “Personal Network Survey for Clinical Research” is available in the REDCap Shared Library. We have also uploaded a comprehensive R codebase for researchers who use the instrument to analyze and visualize their data available at: R code used specifically for this project can be made available upon request.
