Coach access to digital self‐monitoring data: an experimental test of short‐term effects in behavioral weight‐loss treatment
An erratum to this article was published (Obesity (Silver Spring), Feb 2026 ↗)
Authors' conclusion
The short-term efficacy of behavioral weight loss was greater when coaches had direct access to self-monitoring device data. Notably, there also was no evidence of iatrogenic effects of data sharing.
Study context
- Population
- Adults in 12 weeks of group-based behavioral weight-loss sessions via videoconference, instructed to self-monitor weight, physical activity (PA) and dietary intake daily
- Participants
- 322 adults
- Comparison
- Coach access to participants' digital self-monitoring data vs no access
- Coach Share ONn = 161
- Primary endpoint
- Weight loss
- Follow-up
- 12 weeks
Primary result
As reported in the abstract
P = 0.04
Further findings
Self-monitoring of PA (% of days) · more frequent with Coach Share ON
P = 0.006
Self-monitoring of eating (% of days) · more frequent with Coach Share ON
P = 0.007
- Perceived supportive accountability · significantly greater with Coach Share ON
- P < 0.001
PA, attendance, working alliance, self-monitoring of weight
- No significant difference by condition in PA
- P = 0.57
- No significant difference in attendance
- P = 0.42
- No significant difference in working alliance
- P = 0.62
- No significant difference in self-monitoring of weight
- P = 0.12
