Category:Symptom scales

Self-report symptom scales and questionnaires used to measure the levels of illness and disability in ME/CFS patients, Fibromyalgia or other chronic illnesses.

Symptom scales are usually subjective (based on the person's opinion) and so can be at risk of response bias. Symptom scales are a common form of Patient Rated Outcome Measure (PROM) used in clinical trials.

Symptom scales or other forms of self-assessment should be used together with objective measures, e.g., school/work attendance record, distance walked in 6 mins, cardiopulmonary exercise test (CPET), pain medication consumption, or VO2 max.
