Validation of the FAcial and CEphalic PAin INventory (FACE PAIN)

The following specific aims will be addressed:

• to create a user-friendly, self-explanatory instrument (FACE PAIN questionnaire) with pain severity visual analog scales associated with the common locations of facial pain in chronic sinusitis.
• to evaluate the clinimetric reliability and validity of the FACE PAIN questionnaire
• to evaluate the ability of th FACE PAIN questionnaire to detect change in symptoms following medical or surgical treatment
• to quantify a minimally important difference in the FACE PAIN instrument by correlating disease-specific quality of life change (Transition Scale) with FACE PAIN rating changes following treatment.
• to evaluate the correlation between facial pain symptoms described on the FACE PAIN questionnaire with CT scan and endoscopic findings.

The measurements used for the study are: demographics (age, gender and race), contact information (to facilitate mailing of future instruments), Sinonasal Outcome Test-20 (SNOT-20 - a well validated, 20-item measure of rhinosinusitis specific QOL), FAcial and CEphalic PAin INventory (instrument under study) and Translational Quality of Life Form (this transition scale provides a subjective quantification of the degree of change in quality of life from sinusitis); CT scans and nasal endoscopy findings.

Control subjects will complete the SNOT-20 (validated QOL form) and the FACE PAIN a single time.

Case subjects will complete the SNOT-20 and the FACE PAIN questionnaire at the visit during which they review their CT results with the MD. Thereafter, they will complete the FACE PAIN questionaire twice more; at weeks 12 and 14 post that visit. They will also complete the Transition Scale at week 12. These forms will be mailed to the subjects and returned by mail.
