About this study
Official title: Efficacy of the Mobile Phone Application (Circadian Rhythms for Mood) for Prediction and Prevention of Mood Episode Recurrence in Mood Disorders Based on Machine Learning of Daily Digital Phenotype Variables : A Sham-controlled Randomized Clinical Trial
This study was designed to evaluate the efficacy of the mobile application named Circadian Rhythm for Mood (CRM), which was developed to prevent recurring episodes of mood disorders (major depressive disorders, bipolar disorders type 1 and 2) based on machine learning.
- Being tested
- Circadian Rhythms for Mood (CRM) application - Active, Circadian Rhythms for Mood (CRM) application - Sham
- Medical subject headings
- Depressive Disorder, Major, Bipolar Disorder
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Circadian Rhythms for Mood (CRM) application - ActiveOther
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.
Circadian Rhythms for Mood (CRM) application - ShamOther
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.
| Study group | Role | What they receive |
|---|---|---|
| Active CRM | Active comparator | Not described Receives: Other: Circadian Rhythms for Mood (CRM) application - Active |
| Sham CRM | Sham comparator | Not described Receives: Other: Circadian Rhythms for Mood (CRM) application - Sham |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: 12 months
