Tracking Our Lives Study
Impact of Using Self-monitoring Smartphone Applications on College Students' Well-being
College women are at risk for eating disorders, which have profound health impacts. Cross-sectional studies have shown that the use of dietary self-monitoring is associated with eating disorder risk among college students. However, causality cannot be established with cross-sectional studies.
This study utilizes a randomized controlled trial design to examine how the use of a popular dietary self-monitoring smartphone application impacts college females' well-being, including eating disorder risk. We hypothesize those who are randomized to dietary self-monitoring will have a greater increase in eating disorder risk compared to the control group.
