TAP reading note: Inter- and Intrapersonal Associations Between Physiology and Mental Health: A Longitudinal Study Using Wearables and Mental Health Surveys
This commercial-wearable cohort separates between-person, within-person and cross-lagged associations. Some physiological and mental-health measures were associated concurrently, but physiological predictors of subsequent mental health were not significant in the cross-lagged analyses. Some earlier stress measures predicted later physiology. Concurrent association is not a validated prediction tool.

What the study found
This commercial-wearable cohort separates between-person, within-person and cross-lagged associations. Some physiological and mental-health measures were associated concurrently, but physiological predictors of subsequent mental health were not significant in the cross-lagged analyses. Some earlier stress measures predicted later physiology. Concurrent association is not a validated prediction tool.
Scope & limitations
181,574 WHOOP users and approximately 7.94 million wear-days; questionnaire samples varied, and heart-rate-zone activity analyses involved only about 3,196 users.
Device purchase and continued use, recall-based questionnaires and unmeasured environmental or menstrual factors affect interpretation. Person-mean centring does not remove all time-varying confounding. External prospective prediction and calibration remain necessary.
Population & sample
181,574 WHOOP users and approximately 7.94 million wear-days; questionnaire samples varied, and heart-rate-zone activity analyses involved only about 3,196 users.
Exposure or intervention
Physiology/behaviour aggregated over 14 or 28 days before surveys, requiring at least seven valid days; between-person, within-person and cross-lagged models.
Outcomes
Mental-health surveys in relation to HRV, resting heart rate, sleep and activity, separating concurrent and subsequent outcomes.
Time frame
13 months of data, with separately defined survey-history windows and cross-lagged intervals.
Research funding
WHOOP provided salary or income support to all authors; use of the data requires company permission.
Research conflicts of interest
Several authors were WHOOP employees, consultants or contractors. They report no additional company role in design, analysis or publication decisions.
Reading scope
Full-text filtering/aggregation, sample flow, cross-lagged models, results and limitations. External validation and all interval sensitivity analyses have not been rechecked.
