Area of Science:

  • Digital Health
  • Behavioral Science
  • Mobile Health Interventions

Background:

  • Personalized digital health tools are increasingly important for promoting physical activity.
  • Understanding user preferences is key to effective app design and engagement.
  • University students represent a demographic that can benefit from accessible health interventions.

Purpose of the Study:

  • To assess the feasibility and acceptability of the be.well app among university students.
  • To evaluate the personalization approach of the be.well app.
  • To investigate the impact of the app on physical activity levels.

Main Methods:

  • A mixed-methods, pre-post experiment was conducted over 2 months with 23 university students.
  • Usability was measured using a validated questionnaire, and engagement was tracked.
  • Physical activity changes were assessed via daily step count, and qualitative data were gathered through interviews.

Main Results:

  • The be.well app demonstrated good usability (mean score 5.6/7) and acceptable engagement (18/23 participants used it in the final month).
  • Participants favored the personalized activity suggestions for their actionability and promotion of autonomy.
  • A significant increase in daily step count was observed (median difference 1953 steps/day, p <.001).

Conclusions:

  • The be.well app's personalization strategy is feasible and acceptable for university students.
  • Preliminary findings suggest a positive impact on daily physical activity.
  • Further randomized controlled trials with longer follow-up are recommended to confirm effectiveness.
