An interventional study of Wearable device-based intervention (with motivational support via social media) and Wearable device-based intervention (without support) in Sleep and Physical Activity, sponsored by National Chung Hsing University. Completed at 1 site in Taiwan. Open to participants aged 18 Years to 64 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-04-29.

The goal of this randomized controlled trial is to examine whether the use of a wearable device and social media based intention increases physical activity and enhance sleep quality among adults.
The present study aims to study sedentary breaks and sleep quality in Taiwanese adults.
This is a three-arm randomized controlled trial, exploring the effects of a one-month wearable device-based intervention (Garmin tracker) in increasing physical activity and improving sleep quality in adults (Target n = 75 ). The one-month follow-up assessment will be conducted to examine the remaining effects of the intervention.
The main questions it aims to answer are:
Does using a wearable device improve physical activity and improve sleep quality among adults?
Does the inclusion of motivational support provided via social media promote even greater effects in increasing physical activity and improvements in sleep quality?
Researchers will compare groups wearing a device and receiving motivational support via social media (intervention group 1) or wearing a device but without support (intervention 2) to a control condition (participants who do not wear a device and do not receive support) to see whether a wearable device could increase physical activity and improve sleep.
2,426 studies on the registry are indexed under Motor Activity; 1,162 are open to participants now.
This study's enrollment of 75 is above the median of 60 across 2,111 interventional studies indexed under Motor Activity.

Exclusion Criteria:
-
The control group will not wear the device at times other than completing assessments at baseline, post-intervention, and follow-up.
Participants in the Device and motivational support group will wear the device (Garmin tracker) for a month. In addition, they will receive motivational support via social media.
Behavioral: Wearable device-based intervention (with motivational support via social media)
Participants in the Device group will wear the device (Garmin tracker) for a month.
Behavioral: Wearable device-based intervention (without support)
The wearable device-based intervention aims to reduce sedentary behavior as the Move alert function may facilitate the management of one's physical activity. Motivational support will be provided via an online community created using LINE platform. The platform serve for the following purposes: a) providing psychoeduation prior to the intervention; b) providing a place for participants to motivate and encourage each other; c) provide health knowledge to participants weekly, to motivate behavioral change; d) encouraging participants to upload their daily step count to the community page to motivate each other's progress; e) based on participant's performance, research assistants will provide tailored support using Line stickers designed for the present intervention; f) research assistants will monitor participants' step counts and provide prizes (vouchers) for those who had the most step counts and made the most improvements.

Changes in Physical Activity
Change in physical activity will be assessed by self-report measure on sedentary breaks and behaviour (the measure was developed by the investigator in a previous study). In addition, it will also be assessed by a measurable device (physical activity-related parameters assessed by Garmin monitor).
Time frame: Baseline, and post-assessment (immediately after the intervention), one month follow-up
Changes in Sedentary Behavior
All participants randomized to each group with available sedentary behavior questionnaire data were included in this analysis.
Time frame: Baseline, and post-assessment (immediately after the intervention), one month follow-up
Participants were recruited using a convenience sampling approach from students and staff aged 18 years or older at National Chung Hsing University through campus announcements and study advertisements.

The analysis population includes all 75 participants who were randomized into the three study arms (Arm 1, Arm 2, and Arm 3) at baseline. An Intention-to-Treat (ITT) approach was employed, ensuring that all randomized individuals were accounted for in the primary and secondary outcome evaluations to minimize bias.
