Interventions/Control_1

Use of the smartphone app "ASHARE"
The principal investigator will provide participants assigned to the intervention group with access to a smartphone app "ASHARE" for three months. The ASHARE is a native app compatible with iOS (version 12.0 or later) and Android (version 5.0 or later). It is available for free download from the App Store and Google Play, respectively. This application is designed to promote physical activity by incorporating basic behavior change techniques such as self-monitoring, feedback, and data sharing among users. Physical activity data are recorded through integration with Apple Health (for iOS users) and Google Fit (for Android users). In addition, the application utilizes a deep learning model (long short-term memory, LSTM) to predict the user's daily levels of depression and anxiety based on data from the previous day.
It is not mandatory for participants to use the app and they may access it at their own discretion. Ideally, participants are expected to use the application for about five minutes per day to review their physical activity patterns and the predicted mental health scores, while aiming to increase their physical activity levels.
To enhance program adherence, the research team will send reminder emails every two weeks to encourage app usage. The application will also send daily notifications at 6:00 AM to inform participants of their latest predicted depression and anxiety scores via the smartphone's notification system. The research team will monitor app usage, including login frequency and physical activity time, through the management dashboard.

Interventions/Control_2

Active control
Workers engaged in worksites in this group will be asked to download and read a booklet that provides basic information about stress for 6 months. No assistance other than the booklet will be provided.
