Effectiveness of gamified team competition as mHealth intervention for medical interns: a cluster micro-randomized trial

Abstract

Gamification, the application of gaming elements to increase enjoyment and engagement, has the potential to improve the effectiveness of digital health interventions, while the effectiveness of competition gamification components remains poorly understood on residency. To address this gap, we evaluate the effect of smartphone-based gamified team competition intervention on daily step count and sleep duration via a micro-randomized trial on medical interns. Our aim is to assess potential improvements in the factors (namely step count and sleep) that may help interns cope with stress and improve well-being. In 1779 interns, team competition intervention significantly increases the mean daily step count by 105.8 steps (SE 35.8, p = 0.03) relative to the no competition arm, while does not significantly affect the mean daily sleep minutes (p = 0.76). Moderator analyses indicate that the causal effects of competition on daily step count and sleep minutes decreased by 14.5 steps (SE 10.2, p = 0.16) and 1.9 minutes (SE 0.6, p = 0.003) for each additional week-in-study, respectively. Intra-institutional competition negatively moderates the causal effect of competition upon daily step count by −90.3 steps (SE 86.5, p = 0.30). Our results show that gamified team competition delivered via mobile app significantly increases daily physical activity which suggests that team competition can function as a mobile health intervention tool to increase short-term physical activity levels for medical interns. Future improvements in strategies of forming competition opponents and introducing occasional competition breaks may improve the overall effectiveness.

Personalized digital behaviour interventions increase short-term physical activity: a randomized control crossover trial substudy of the MyHeart Counts Cardiovascular Health Study

“… 32 However, in a trial of young medical interns, gamified intervention via mobile phone app was significantly associated with increased short-term physical activity, however, with waning casual effects over time. 33 These results suggest that while there is a significant increase in physical activity with app-based digital interventions, 29 the effect wanes over time with decreased app engagement 33 and may not be present in populations with significant medical comorbidities. 30–32 Further work is needed in high-risk groups that would benefit from exercise (e.g.…”

Influence of Gamification on the Commitment of the Students of a Programming Course: A Case Study

“…The integration of gamification in educational settings, particularly in programming courses, has been a topic of growing interest in recent years [14]. The potential benefits of gamification, such as increased student engagement, motivation, and improved learning outcomes, have been highlighted in various studies [15][16][17][18][19]. However, the specific influence of gamification on student commitment in programming courses remains an area that warrants further exploration.…”
