Augmented Reality Location-Based Games on Physical Activity

Condition(s) studied

Investigational drug(s) / intervention(s)

AR location-based game: This study aims to utilize the AR location-based game Pikmin Bloom to gradually encourage middle-aged and older adults in the community to develop a habit of walking outdoors. A step goal will be set every two weeks to progressively increase daily walking activity. By integrating the AR game with a LINE chatbot for feedback and engagement, this approach aims to motivate older adults, enhance their willingness to go outside, and increase their daily step count.

Study summary

This study aims to examine the effects of an augmented reality location-based game intervention on behavioral and psychological factors related to physical activity among middle-aged and older adults. The study adopts a quasi-experimental design, targeting community-dwelling individuals aged 40-59 or 60 and above, who engage in sedentary work patterns exceeding 6 hours daily. Recruitment is scheduled to commence in February 2025 at the Xinyi Health Service Center in Taipei City. Participants will be assigned to either the experimental group or the control group based on enrollment timing. A minimum of 41 participants will be recruited, divided into two experimental groups and two control groups. The experimental group will participate in an augmented reality location-based game featuring different step count goals every two weeks, daily step count reporting, and goal achievement encouragement. The control group will maintain their usual routines without any intervention. The intervention will last for 8 weeks. Research instruments will include a basic demographic questionnaire, the short-form Taiwan Physical Activity Questionnaire, the Exercise Self-Efficacy Scale, the Exercise Motivation and Barriers Scale, blood pressure measurements, and the Quality of Life Scale.

Eligibility

Primary outcome measure(s)

• International Physical Activity Questionnaire short-form — Baseline, through study completion, an average of 12 weeks
  It consists of 7 items that ask about physical activity over the last 7 days. These items cover vigorous activities, moderate activities, walking, and sitting (MET-minute/week)
• Exercise Self-Efficacy Scale — Baseline, through study completion, an average of 12 weeks
  Participants achieved a response if they scored an exercise self-efficacy score between 1 and 10.
• The Exercise Motivation and Barriers Scale — Baseline, through study completion, an average of 12 weeks
  It typically includes a series of statements related to exercise benefits and barriers. Participants rate their agreement with each statement on a Likert scale (5 strongly agree to 1 strongly disagree)
• WHO Quality of Life Scale. — Baseline, through study completion, an average of 12 weeks
  A shorter version with 26 questions. The scale evaluates various aspects of life, including physical health, psychological state, social relationships, and environmental factors, scored between 1 and 5.
