Testing the Effectiveness of an Intervention That Aligns Circadian Rhythm With Daily Activities on Student Flourishing
(Not Required)
What this study is about
Previous studies have examined whether circadian rhythm tracking improves well-being, with some evidence suggesting that aligning daily activities with one's natural chronotype (a person's natural preference for being alert and sleep), enhances well-being and productivity. However, the current research lacks intervention-based designs like real-time tracking or behavioral alignment tools.
View original scientific description
Previous studies have examined whether circadian rhythm tracking improves well-being, with some evidence suggesting that aligning daily activities with one's natural chronotype (a person's natural preference for being alert and sleep), enhances well-being and productivity. However, the current research lacks intervention-based designs like real-time tracking or behavioral alignment tools. Here, the investigators aim to investigate if an active intervention, involving the usage of an app tracking circadian rhythms and making recommendations based on one's circadian rhythm over seven weeks, improves students' flourishing.
Interventions
BEHAVIORAL
Use of Owaves App
Students use the Owaves app for 7 weeks and psychological measures are obatined pre and post to determine the effectiveness of the App
Primary outcome measures
Trait Happiness (Subjective Happiness Scale)
Time frame: Baseline (Weeks 1/2) and Weeks 8/9.
Subjective Happiness Scale (SHS) Trait questionnaire. The SHS is a 4-item scale of global subjective happiness. It is scored on a 7-point Likert scale where 1 = less happy to 7 = more happy. Total scores range from 4 to 28 where higher scores indicate greater subjective happiness.
Focus Trait (Barkley Adult ADHD Rating Scale (Inattention Subscale) and Academic Time Management and Procrastination Measure)
Time frame: Baseline (Weeks 1/2) and Weeks 8/9.
The Barkley Adult ADHD Rating Scale is a self-report questionnaire with 18-items which rates the frequency of ADHD symptoms and behaviors. Each item is scored on a 4-point scale ranging from 1 = never or rarely, to 4 = very often. A lower score indicates less severe ADHD symptoms and behaviors.
Energy Trait (Subjective Vitality Scale)
Time frame: Baseline (Weeks 1/2) and Weeks 8/9.
Subjective Vitality Scale (SVS) is a 6 - item self-report questionnaire to measure the subjective vitality of a participant. It is scored on a 7-point Likert scale where 1 = completely disagree to 7 = completely agree. Higher scores indicates higher level of subjective vitality.
Mindfulness Trait (Five Facet Mindfulness Questionnaire (FFMQ))
Time frame: Baseline (Weeks 1/2) and Weeks 8/9.
The Five Facet Mindfulness Questionnaire (FFMQ) short form is a 24-item questionnaire that measures mindfulness in participants. Items are scored on a 5-point Likert-type scale ranging from 1 = never/very rarely true to 5 = very often/always true. Higher scores indicate greater levels of mindfulness.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
