Brief summary
Fibromyalgia is a chronic condition that commonly causes widespread pain, fatigue, and difficulty in daily activities. These symptoms may change from day to day, even when their average severity is similar. This study aims to examine whether daily changes in pain and fatigue are related to functional impact in adults with fibromyalgia. Participants will complete clinical questionnaires at the first visit and record their pain and fatigue levels for seven days. Sleep quality and perceived control over symptoms will also be recorded. No treatment or additional medical procedure will be given as part of the study.
Detailed description
Fibromyalgia symptoms do not always remain at the same level. Pain and fatigue may increase or decrease between days and may also change between morning and evening. Clinical assessments usually focus on the average severity of these symptoms. However, patients with similar average pain or fatigue levels may have different levels of difficulty in daily life. This study will therefore examine whether symptom fluctuation provides additional information about functional impact beyond average symptom severity. Adults diagnosed with fibromyalgia according to the 2016 American College of Rheumatology criteria will be included. At the initial visit, demographic and clinical information will be recorded. Functional impact will be assessed using the Fibromyalgia Impact Questionnaire. Anxiety and depression symptoms will be assessed using the Hospital Anxiety and Depression Scale, and symptoms related to central sensitization will be assessed using the Central Sensitization Inventory. After the initial visit, participants will record pain and fatigue levels every morning and evening for seven days using 0-10 numerical rating scales. They will also record their sleep quality each morning and their perceived control over symptoms once daily. These records will be used to calculate average pain and fatigue levels, daily fluctuations in these symptoms, maximum symptom levels, and the degree to which pain and fatigue change together within each participant. The main analysis will examine the relationship between pain and fatigue fluctuations and functional impact. It will also evaluate whether symptom fluctuation is related to functional impact after considering average pain and fatigue levels, age, sex, and disease duration. Additional analyses will examine the relationships of pain-fatigue synchrony, sleep quality, maximum symptom levels, and perceived symptom control with functional impact. The study is observational and is not designed to determine cause-and-effect relationships.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Functional Impact Assessed by the Fibromyalgia Impact Questionnaire | At the initial visit | Functional impact will be assessed using the Fibromyalgia Impact Questionnaire (FIQ). The total score ranges from 0 to 100, with higher scores indicating greater impact of fibromyalgia. The main analysis will examine whether within-person variability in pain and fatigue over seven days is associated with the FIQ score independently of average pain and fatigue levels. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Within-Person Association Between Pain and Fatigue | During the 7-day monitoring period | Participants will rate pain and fatigue every morning and evening for seven days using 0-10 numerical rating scales. The within-person correlation between paired pain and fatigue ratings will be calculated for each participant. The relationship between this correlation and the FIQ total score will be examined. |
| Maximum Pain and Fatigue Levels | During the 7-day monitoring period | The highest pain rating and the highest fatigue rating reported by each participant during the seven-day monitoring period will be identified separately. Both are measured on scales from 0 to 10, with higher scores indicating greater symptom severity. Their relationships with the FIQ total score will be examined. |
| Perceived Symptom Control | During the 7-day monitoring period | Participants will rate their perceived control over their symptoms once daily for seven days using a scale from 0 to 10. The relationship between perceived symptom control and the FIQ total score will be examined. |
| Sleep Quality | During the 7-day monitoring period | Participants will rate the quality of the previous night's sleep each morning for seven days using a scale from 0 to 10. The relationships of sleep quality with pain, fatigue, and the FIQ total score will be examined. |
