Abstract
Statement of the Problem: WHO has declared obesity and overweight an epidemic and emphasizes its significant relation with other chronic conditions, including cardiovascular disease, hypertension, cancer, type-2 diabetes, osteoarthritis, gout and hypoxemia. Smart phone applications have drawn attention as a potential intervention to promote physical fitness and provide preventive care for obesity and overweight but they face a great challenge due to low sustained usage. In this study, we examine whether participation in user contests is associated with sustained use of a fitness app even after the contest ends.
Methodology & Theoretical Orientation: Drawing upon the social comparison theory and the self-efficacy theory, we hypothesize that contestant participation increases the probability of sustained usage of the fitness app. We used data from 8,204 users of a fitness app that counts the daily walking steps. We identified user compliance levels with two unsupervised clustering methods: dynamic time warping (DTW) and k-means clustering.
Findings: Our results show that contestants have significant effects on post-contest compliance. However, the effect is significant only when users are highly compliant during the contest, highlighting that it is important to design contests to encourage users to be more compliant during the contests.
Conclusion & Significance: Our research provides several important implications for further studies as well as for the obesity and overweight management. One of the key implications of this study is that contests can have significant effects on post-contest usage only when users actively participate in the contest, indicating that participation itself is not enough to improve post-contest usage. Rather, it is more important to design contests to encourage users to be more active during the contests.
