Objective[edit | edit source]

The FIQ is an assessment and evaluation instrument developed to measure fibromyalgia (FM) patient status, progress and outcomes. [1]

Intended Population[edit | edit source]

It has been designed to measure the components of health status that are believed to be most affected by FM.

Method of Use[edit | edit source]

The FIQ is a self administered instrument that takes approximately 5 minutes to complete. The directions are simple and the scoring is self-explanatory.

The FIQ is composed of 10 items. The first item contains 11 questions related to physical functioning – each question is rated on a 4 point Likert type scale. Items 2 and 3 ask the patient to mark the number of days they felt well and the number of days they were unable to work (including housework) because of fibromyalgia symptoms. Items 4 through 10 are horizontal linear scales marked in 10 increments on which the patient rates work difficulty, pain, fatigue, morning tiredness, stiffness, anxiety and depression.

Evidence[edit | edit source]

This initial assessment indicates that the FIQ has sufficient evidence of reliability and validity to warrant further testing in both research and clinical situations.
