CLEAR ANSWERS TO COMMON QUESTIONS

Frequently Asked Questions

Any questions left?

What does this questionnaire measure?

It screens for symptoms and patterns commonly linked to increased central nervous system sensitivity. It estimates how strongly this mechanism may be contributing to current symptoms.

Who is this questionnaire intended for?

It is used for people with persistent pain or heightened sensitivity, including conditions such as fibromyalgia, migraine, or widespread pain. It may also be used when symptoms seem out of proportion to typical findings.

How long does it take and how many items are included?

It includes 25 items and usually takes about 5 minutes to complete.

How should items be answered?

Select the response that best reflects how often each symptom has been present recently. Answer all items based on typical experiences rather than rare events.

How are results used?

Scores provide a summary of symptom burden related to central sensitization and support clinical interpretation. Results do not diagnose a condition and should be reviewed with other clinical information.

WHAT THE TEST MEASURES

About This Assessment

Central Sensitization Inventory (CSI-R) Test

somatics

This self-report measure is used to screen for symptoms commonly associated with central sensitization and related patterns of heightened central nervous system responsivity. The Central Sensitization Inventory (CSI-R) was developed to support efficient clinical characterization of symptom burden in patients presenting with chronic or complex pain complaints.

The instrument contains 25 items and typically takes about 5 minutes to complete. Items assess the frequency or severity of somatic and sensory symptoms that may be consistent with central sensitization; results are intended to inform clinical formulation and guide follow-up assessment rather than serve as a standalone diagnosis. The Central Sensitization Inventory (CSI-R) is commonly referenced in the pain and behavioral health literature (Sullivan & Turk) and can be integrated with history, examination findings, and other validated measures.
