Basic Scale Structure

The EAR-Q was developed for use with all types of ear conditions and treatments. The content for EAR-Q was developed from qualitative interviews with 25 patients aged 8 to 21 years with Microtia, prominent ears and other less common ear conditions. The scales were refined with patient and expert input. The EAR-Q was then translated into multiple languages in preparation for field-testing. Data collection took place as part of the FACE-Q | Craniofacial field-test study.

EAR-SPECIFIC SCALES

The EAR-Q includes 2 ear-specific scales. The 10-item Appearance scale measure how the ear(s) look from the patient perspective. Items ask about ear shape and size, as well as how the ears look in photos, from the side and when wearing a hat, etc. The 10-item Adverse Effects scale measures how a patient’s ear feels and other concerns. Items ask about itchiness, pain, bruising and discoloration, etc.

HEALTH-RELATED QUALITY OF LIFE

In addition to the ear-specific scales, scales measuring psychological, social and school function developed as part of the CLEFT-Q, and a scale measuring appearance-related distress as part of FACE-Q | Craniofacial, were shown to have content validity for use in patients aged 8 to 29 years with ear conditions. All 4 health-related quality of life scales evidenced strong psychometric properties in large international field-test samples that included patients with a range of ear conditions.
