Diabetes self-management in the age of social media: Large-scale analysis of peer interactions using semi-automated methods
ABSTRACT
Background:
Online communities have been gaining popularity as support venues for chronic disease management. User engagement, information exposure, and social influence mechanisms can play a significant role in the utility of these platforms.
Objective:
In this paper, we characterize peer interactions in an online community for chronic disease management. Our objective is to 1) identify key communication themes and 2) study their prevalence in online social interactions.
Methods:
The American Diabetes Association Online community is an online social network for diabetes self-management. We analyzed 80,481 randomly selected de-identified peer-to-peer messages from 1,212 members, posted between June 1, 2012 and May 30, 2019. Our mixed-methods approach comprised qualitative coding and automated text analysis to identify, visualize, and analyze content-specific communication patterns underlying diabetes self-management.
Results:
Qualitative analysis revealed that “Social support” was the most prevalent theme (84.9%), followed by “readiness to change” (18.8%), “teachable moments” (14.7%), “pharmacotherapy” (13.7%), and “progress” (13.3%). The support vector machine classifier resulted in reasonable accuracy with recall=0.76 and precision= 0.78, and allowed us to extend our thematic codes to the entire dataset.
Conclusions:
Modeling health-related communication through high throughput methods can enable the identification of specific content related to sustainable chronic disease management, which facilitates targeted health promotion.
