Dynamic simulation of social media challenge participation to examine intervention strategies
Khasawneh, A., Madathil, K. C., Taaffe, K. M., Zinzow, H., Ponathil, A., Madathil, S. C., … Rosopa, P. J. (2022, September 16). JOURNAL OF COMPUTATIONAL SOCIAL SCIENCE, Vol. 9.
author keywords: Agent-based model; Web-based challenges; Self-injurious behavior; Behavior; Integrated behavioral model; Social media
TL;DR:
This paper shows how agent-based modeling (ABM) can be used to investigate the effect of educational intervention programs to reduce participation in social media challenges at multiple levels—family, school, and community, and suggests that educational interventions at combined family and school levels are the most efficient type of long-term intervention.

EVALUATING DIABETIC RETINOPATHY SCREENING INTERVENTIONS IN A MICROSIMULATION MODEL
2020 WINTER SIMULATION CONFERENCE (WSC), pp. 944–955.
TL;DR:
A microsimulation integrating the natural history model of DR with a patient’s interaction with the care system increased adherence of patients with vision-threatening DR to follow-up eye care, decreased the number of ‘unnecessary’ visits in specialty eye care from patients without VTDR, and decreased the total years spent blind.
