Article Synopsis
  • Social participation is essential for the well-being of older adults, but often declines due to aging factors; mobile health apps might help but their impact is not thoroughly studied.
  • A trial tested a mobile app, ESP, designed to boost social participation and physical activity in older adults by offering features like self-monitoring and gamification, with 181 participants divided into intervention and control groups.
  • Results showed that the intervention group using the ESP app had a significant increase in social participation frequency compared to the control group, especially in hobbies and cultural activities.
