Outcome Measures

Primary Outcomes (2)

  • Comparison of total number of recurrent mood episodes between the active and sham groups

    We aim to evaluate the efficacy of reducing recurrence rate of mood episodes through the CRM mobile application.

    12 months

  • Comparison of duration of mood episodes between the active and sham groups

    We aim to evaluate the efficacy of reducing duration of mood episodes through the CRM mobile application.

    12 months

Study Arms (2)

Active CRM

ACTIVE COMPARATOR
Other: Circadian Rhythms for Mood (CRM) application - Active

Sham CRM

SHAM COMPARATOR
Other: Circadian Rhythms for Mood (CRM) application - Sham

Interventions

The study subjects participating in this clinical trial wear wearable activity tracker 24 hours a day for a continuous period of time and run the CRM app once a day to check their conditions (feelings, vitality, sleep, etc.) in the Daily Symptom Assessment (eMoodChart). The active intervention group are provided with mood prediction results and instructions as feedback through the 'life report' and push notification in the application.

Active CRM

The study subjects assigned to the sham intervention group are provided with feedbacks operated by dummy algorithm. The application is visually indistinguishable from active CRM, and it is designed to minimize behavioral change.

Sham CRM
