Factors to Affect the Provision of Health Data of Users Through PHR App

Researchers send a weekly message to participants asking them to share their step data on their personal health records(PHR) applications. (4months in total)

(Baseline, 1month) For the first month, researchers send the same data request message to both counties.

1. term, 1 month) The researchers added a message saying, 'Incentives are provided for data sharing' only to the experimental group.
2. term, 1 month) Excludes incentive message for both groups

3. term, 1 month) The researchers added a message saying, 'Incentives are provided for data sharing' only to the control group.

   • For equity in both groups, an incentive message was provided to the control group in the last month under the same conditions as the experimental group.
   • Only the first 3 months of data were used for the study.

Hypothesis

• In 1-term, the number of data sharing in the experimental group is higher than that in the control group.
• In 1-term, the number of data sharing in the experimental group is more active than baseline period.
• In 2-term, the number of data sharing in the experimental group is still higher than in the baseline period.
• Over the next 1 month, the number of sharing in the experimental group was maintained, which was still higher than that of the control group.
