Employee well-being in the digital age: Assessing the impacts of a smartphone application in the workplace

Abstract

Recently, providing smartphone-based health-improving applications to employees has emerged as a promising strategy for sustaining their well-being. This study estimates the impact of the routine use of an application, introduced in 2020 by a Japanese manufacturing company, on various health-related behaviours and outcomes among employees by exploiting a distinctive large-scale longitudinal dataset and personnel records. The analysis addresses potential selection biases arising from the non-random nature of application usage by employing the instrumental variable approach. Regular application use generates significant positive impacts on health-related habits, including moderate alcohol consumption, regular breakfast intake and refraining from eating two hours before bedtime. Furthermore, regarding physical and psychological stress, noteworthy reductions in physical burden and less frequent experiences of annoyance are observed. Employees also report a lower frequency of dizziness, headaches and palpitations, albeit an increase in the frequency of strained eyes is noted. Additionally, application use is associated with lower systolic and diastolic blood pressure, as well as decreased levels of triglycerides and gamma-GTP.
