Description of intervention(s) / exposure
Multiple sclerosis (MS) is a condition of the central nervous system, where there is interference in the nerve impulses within the brain, spinal cord and optic nerves. Scars occur within the central nervous system and depending on where they develop, manifest into various symptoms. Some symptoms include problems with motor control (muscle spasms, weakness, lack of coordination/balance and functioning of arms and legs) neuropsychological issues (memory loss and cognitive issues), bladder and bowel incontinence, and other neurological symptoms such as vertigo, pins and needles, neuralgia and visual disturbances. Fatigue is among the most commonly reported, most disabling but least understood symptom experienced by patients with MS. Patients differ substantially in the symptoms they experience depending on where lesions have developed on the brain and spinal cord. Factors such as physical activity, sleep, stress and mood may trigger, worsen or co-occur with symptoms.

In this study, participants will complete questionnaire items about fatigue and potential triggers (e.g. physical activity, sleep, stress, mood) on a daily basis for period of 6-18 weeks via an electronic diary with an inbuilt accelerometer. Questionnaire items related to personally-relevant symptoms (e.g. body pain) and potential triggers of fatigue (e.g. sleep) will be selected by participants at the start of the study and incorporated into to the design of the daily questionnaires. Brief questionnaires will be completed by participants three times per day (morning, afternoon and evening) and will take approximately 1-2 minutes to complete.

Outcomes
Primary outcome [1] 324527 0
The severity of fatigue measured on a visual analogue scale ranging from 0 to 100. The measure is designed specifically for this study. The data is analysed at the individual (N-of-1) level.
Timepoint [1] 324527 0
Three times per day (morning, afternoon and evening) for 6-18 weeks (duration of data collection period based on the preference of the participant).
Secondary outcome [1] 384885 0
The severity of a personally-relevant symptom (e.g. body pain) selected by the participant at the start of the study measured on a visual analogue scale ranging from 0 to 100. The measure is designed specifically for this study. The data is analysed at the individual (N-of-1) level. If more than one symptom is selected by the participant, it will be analysed as another secondary outcome (i.e. not a composite measure).
Timepoint [1] 384885 0
Three times per day (morning, afternoon and evening) for 6-18 weeks (duration of data collection period based on the preference of the participant).
Secondary outcome [2] 385798 0
Acceptability of the study procedures
Timepoint [2] 385798 0
Semi-structured interviews will be conducted at the end of the study to explore participant views about the study procedures
Secondary outcome [3] 385799 0
Feasibility of study procedures
Timepoint [3] 385799 0
Feasibility will be assessed by calculating the recruitment/retention rate and completion rate of daily questionnaires during the study for each participant after the data collection period is completed.

Statistical methods / analysis
Statistical power in N-of-1 studies is determined by the number of repeated measurements from the same individual. Therefore, there are no sample size requirements related to the number of participants recruited.

Individual level and aggregated analyses will be performed. Individual level analyses will be conducted using Bayesian time series analysis. Aggregated analyses will be conducted using Bayesian hierarchical models.

Summary
Brief summary
This research study aims to explore intra-individual variability in symptoms over time and intra-individual predictors of symptom severity. A series of N-of-1 observational studies with individuals with Multiple Sclerosis (MS) will be conducted. The study also aims to assess the acceptability and feasibility of participating in N-of-1 observational studies from the perspective of individuals with MS. This will be achieved by conducting semi-structured interviews with participants at the end of the study and by examining recruitment and retention rate and questionnaire completion rates.
