Brief Summary
This Personalized Trial will test the feasibility and effectiveness of employing technology to facilitate remote N-of-1 interventions to research participants with self-identified fatigue. Participant's initial levels of fatigue and other outcomes will be assessed in a baseline period 2 weeks in length. Participants will spend 12 weeks alternating between bright light therapy, dim light therapy, and usual care methods to treat their fatigue, while answering daily questions and wearing an activity tracker. After 14 weeks, participants will have the ability to share their opinions about the Personalized Trials platform. The investigators believe a Personalized Trials platform will be satisfactory to participants and feasible to scale to large randomized controlled trials, and eventually to clinical practice.

Outcome Measures
Primary Outcomes (1)
Mean System Usability Score (SUS).
The SUS is a validated 10-item questionnaire that asks users to score each item on a Likert scale from Strongly Disagree (rating of 1) to Strongly Agree (rating of 5). The SUS will be presented to the participant as addressing the ease of use, complexity, consistency of the Personalized Trials system as a whole, from recruitment to receipt of the report. Individual results are calculated to arrive at a composite measure out of 100. Participant SUS scores will be averaged together and an overall mean will be reported with standard deviation. Higher scored values correlate to a more usable system, and therefore a better outcome.
Assessed once after the results report has been sent to the participant, within 4 months of intervention completion.
Secondary Outcomes (16)
Within-Subject Difference in Self-reported Daily Fatigue Assessed Using the PROMIS Item Bank v1.0 Fatigue 7b Daily
Daily fatigue will be assessed daily via survey during the baseline assessment period (2 weeks) and during each of the 6 treatment periods (2 weeks each).
Within-Subject Difference in Self-reported Weekly Fatigue Assessed Using the PROMIS Item Bank v1.0 Fatigue 8a.
Weekly fatigue will be assessed weekly via survey during the baseline assessment period (2 weeks) and during each of the 6 treatment periods (2 weeks each).
Within-Subject Difference in Ecological Momentary Assessment (EMA) of Fatigue.
EMA fatigue will be assessed 3 times daily via text message during the baseline assessment period (2 weeks) and during each of the 6 treatment periods (2 weeks each, 12 weeks total).
Participant Satisfaction With Personalized Trial Components.
Assessed once after the results report has been sent to the participant, within 12 weeks of the study period.
Within-Subject Difference in Ecological Momentary Assessment (EMA) of Pain.
EMA pain will be assessed 3 times daily via text message during the baseline assessment period (2 weeks) and during each of the 6 treatment periods (2 weeks each, 12 weeks total).
- +11 more secondary outcomes
Other Outcomes (1)
Within-Subject Difference in Self-Reported Side Effects.
Self-reported side effects will be assessed via weekly survey during the baseline assessment period (2 weeks) and during each of the 6 treatment periods (2 weeks each, 12 weeks total).
Study Arms (3)
Bright Light Therapy
EXPERIMENTALIndividuals will receive bright blue light therapy using glasses developed by AYO. During treatment blocks for bright blue light therapy, participants will receive a text message within an hour of their self-reported wake time instructing them to use their designated light therapy device for 30 minutes. Bright blue light therapy will be administered in 2 treatment periods each 2 weeks in length (4 weeks total). Bright blue light treatment has been previously identified as an efficacious treatment for fatigue. It has also been shown in a number of studies that the blue wavelength of light is a key component to the shift of fatigue measures in patient reported outcomes.
Dim Light Therapy
ACTIVE COMPARATORIndividuals will receive dim blue light therapy using glasses developed by AYO. During treatment blocks for bright blue light therapy, participants will receive a text message within an hour of their self-reported wake time instructing them to use their designated light therapy device for 30 minutes. Dim blue light therapy will be administered in 2 treatment periods each 2 weeks in length (4 weeks total).
Usual Care
NO INTERVENTIONDuring usual care periods, participants will be instructed to abstain from use of AYO light therapy devices, and instructed to treat their fatigue as they normally would. Usual care will be presented in 2 periods each 2 weeks in length (4 weeks total).
Interventions
AYO light therapy glasses are a commercially available device which have 4 Light-emitting diodes (LEDs) with a dominant wavelength of approximately 470nm ± 2nm and typical irradiance (100% intensity) of approximately 250 µW/cm². AYO bright light glasses are classified as "exempt" for photo-biological risk based on the international standard and conformity assessment for photo-biological safety of lamps (IEC 62471).
AYO light therapy glasses were made available to the research team by the vendor. The device has 4 Light-emitting diodes (LEDs) with a dominant wavelength of approximately 470nm ± 2nm and reduced irradiance (1% intensity) of approximately 250 µW/cm². AYO dim light glasses are classified as "exempt" for photo-biological risk based on the international standard and conformity assessment for photo-biological safety of lamps (IEC 62471).

- Time Frame
- The study protocol, including the statistical analysis plan, will be made available in addition to the informed consent form before the first participants randomized into the study. De-identified, pooled individual participant data will be made available within a year of final participant data collection. We anticipate this data to be available on the Open Science Framework platform indefinitely.
- Access Criteria
- All data and supporting information will be stored on the Open Science Framework, a free web application with no access restrictions.
All collected individual participant data (IPD) will be de-identified and pooled before sharing on the Open Science Framework, along with a data dictionary. Pooling N-of-1 trials together is a more efficient approach to deriving population-level estimates than conventional randomized controlled trials.
