Study 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.
Primary Outcome
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
