High-achieving academic and entrepreneurial populations face elevated risks of chronic stress, anxiety, and burnout. These populations often underutilize mental health services due to stigma, time constraints, or accessibility issues. Digital interventions provide an opportunity to deliver evidence-based stress and resilience support at scale.

The WONE (Walking on Earth, Ltd.) platform integrates personalized stress-resilience assessments, behavioral science micro-interventions, and optional wearable data feedback. This project aims to evaluate the feasibility, engagement, and preliminary efficacy of the WONE digital intervention in multiple Stanford-affiliated cohorts.

Primary Objective To evaluate whether engagement with the WONE app improves resilience, emotional well-being, and stress management outcomes among Stanford-affiliated adults.

Secondary Objective To evaluate the feasibility of wearable-device integration.

Rationale for Two-Phase Structure This protocol includes two sequential studies.

1. Phase 1 (Pilot): A single-arm feasibility pilot designed to assess acceptability of the WONE digital intervention, verify that onboarding, survey workflows, and data capture function smoothly, and identify any usability issues before running a randomized trial.
2. Phase 2 (Randomized Crossover RCT): A fully powered evaluation of the efficacy of WONE, using a 12-week crossover design to compare intervention vs. control periods, followed by a 6-month follow-up to evaluate maintenance of effects.

Phase 1 Objectives (Pilot)

1. Assess feasibility and acceptability of the WONE digital intervention over 8 weeks.
2. Evaluate preliminary changes in resilience, emotional well-being, and stress management from baseline to Week 8. Secondary analysis will also explore changes in symptoms related to anxiety and depression.
3. Describe engagement patterns and examine whether engagement relates to changes in outcomes.
4. Assess feasibility of wearable integration, including connection rates and data completeness.

Phase 2 Objectives (Randomized Crossover RCT)

1. Test the efficacy of the WONE intervention compared to a control period using a 12-week crossover design.
2. Examine changes in resilience, emotional well-being, and stress management across intervention vs. control phases. Secondary analysis will also explore changes in symptoms related to anxiety and depression.
3. Investigate engagement as a predictor of improvement.
4. Evaluate maintenance of effects at the 6-month follow-up.

Inclusion Criteria:

1. Aged between 18 and 65 years with Stanford affiliation
2. English proficiency with the ability to read, write, and complete surveys in English
3. Smartphone with internet access
4. Willingness to complete surveys and app activities
5. Resides in the US
6. Stanford affiliation
7. Wearable device for Phase 1 Pilot Study

Exclusion Criteria:

1. Severe psychiatric instability, defined as any of the following self-reported on the pre-enrollment screener:

   1. Psychiatric hospitalization for a mental health crisis in the past 12 months.
   2. Current mental health symptoms that significantly impair ability to function in daily life (e.g., unable to work, attend school, or care for basic needs).

2. No smartphone or unwilling to consent.

This is a pilot study and early phase study. The plan for sharing individual participant data has not yet been determined. Study team will update after study has completed its enrollment.
