Sharing Digital Self-Monitoring Data With Others to Enhance Long-Term Weight Loss (FitLink)

September 24, 2025 updated by: Drexel University

Sharing Digital Self-Monitoring Data With Others to Enhance Long-Term Weight Loss: A Randomized Trial Using a Factorial Design

Adults attempting weight loss through lifestyle modification (LM) typically find maintenance of behavior change difficult. Outcomes might be improved if participants are provided with sustained sources of accountability and support and ongoing opportunities to reflect with others on goal progress. This study proposes that sharing digital data with other parties has the potential to improve long-term weight loss. The proposed study will enroll adults ("index participants") (N = 320) with overweight/obesity in a 24-month LM program and instruct them to use digital tools for self-monitoring of weight, physical activity, and eating on a daily basis.

Detailed Description

Adults attempting weight loss through lifestyle modification (LM) typically find maintenance of behavior change difficult. Outcomes might be improved if participants are provided with sustained sources of accountability and support and ongoing opportunities to reflect with others on goal progress. This study proposes that sharing digital data with other parties has the potential to improve long-term weight loss. The proposed study will enroll adults ("index participants") (N = 320) with overweight/obesity in a 24-month LM program and instruct them to use digital tools for self-monitoring of weight, physical activity, and eating on a daily basis. Groups will meet remotely each week in months 1-3 to initiate weight loss. In months 4-24, intervention contact will be remote and will include the following: quarterly group meetings held via videoconference; brief phone calls with the coach held twice per quarter; and monthly text messages with the coach, with a small group of fellow group participants, and with a friend or family member outside of the program. Text message content will vary according to treatment condition, i.e. three types of data sharing partnerships: Coach Share, Group Share, and Friend/Family Share. Outcomes will be measured at months 0, 3, 6, 12, and 24. Primary aims include determining if Coach Share, Group Share, and Friend/ Family Share each improve long-term weight loss, PA, and calorie intake, and examining if effects are additive when participants are assigned to engage in more than one type of data sharing partnership. The secondary aim is to explore mediators and moderators of intervention effects. The tertiary aim is to determine how the quality of relationship with coach, group members, and friends/family member over time may differentially moderate treatment effects and predict data sharing efficacy. As digital technology makes data sharing increasingly feasible, it is critical to determine how to optimize these partnerships to improve long-term outcomes in LM.

Experimental: Coach Share On + Group Share On + Friend/Family Share On
Behavioral: Coach Share On
If an index participant is randomized to have Coach Share ON, the coach will have continuous access to objective, real-time, detailed device data, and address data directly in all individual interactions with index participants (groups, individual weigh-ins, phone calls, texts), conveying that they are closely monitoring progress.
Behavioral: Group Share On
If Group Share is ON, participants in a given LM group will view and respond to aspects of each other's self-monitoring device data in their small-group text messages. Each small group participant's data will be highlighted one day of the month, and content from the Group Share Off message library also will be sent.
Behavioral: Friend/Family Share On
Index participants who are randomized to have Friend/Family Share ON will give their friend or family member access to their self-monitoring data. Text messages sent by the program bot, which includes the index participant and friend/family member, will use a similar format as described in Group Share ON. The friend or family member will be trained to respond to data in ways that enhance the participant's motivation and self-regulation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Weight
Time Frame: 0 month, 3 month, 6 month, 12 month, 24 month
Weight will be measured using a wireless scale. In order to maximize accuracy, we will (1) provide instructions (e.g., place scale on flat, hard surface; weigh upon waking, without clothes, after using the bathroom), (2) require participants to confirm that they are following instructions at each assessment point, (3) remove errant weights (e.g., >1 kg change in 1 day).
0 month, 3 month, 6 month, 12 month, 24 month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Physical Activity
Time Frame: 0 month, 3 month, 6 month, 12 month, 24 month
Minutes per week of moderate-to-vigorous PA will be measured by using FitBit. Steps per day from the Fitbit also will be examined.
0 month, 3 month, 6 month, 12 month, 24 month
Calorie Intake
Time Frame: 0 month, 3 month, 6 month, 12 month, 24 month
Average calorie intake over 7 days will be derived from the Fitbit digital food log as a secondary outcome.
0 month, 3 month, 6 month, 12 month, 24 month

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

3 months, 6 month, 12 month, 24 month
Self-monitoring
Time Frame: Calculated continuously for 24 months
(Mediator, moderator) will be objectively measured as the number of days in which digital devices were used to measure weight, record eating, or PA.
