CUSTOMIZABLE FOR DIFFERENT NEEDS

CLEFT-Q is designed to provide clinicians and researchers with the ability to tailor their own version of the questionnaire to suit their needs.

The CLEFT-Q is for anyone with cleft lip and/or palate aged 8 to 29 years. The CLEFT-Q has an eating/drinking checklist and 12 scales that measure 3 overarching domains of Facial Appearance, Facial Function, and Quality of Life.

Advancing Knowledge &
Improving Health Outcomes

Research

CLEFT-Q was field-tested with 2434 patients with cleft lip and/or palate at 30 hospitals in 12 countries.

Industry

Can be used in international clinical trials of craniofacial treatments.

Benchmarking

Included in ICHOM Standard Sets for craniofacial conditions to enable hospitals around the world to compare outcomes.

Patient Care

Designed using a modern psychometric approach to facilitate use in patient care.

Basic Scale Structure

The CLEFT-Q is designed to provide clinicians and researchers with the ability to tailor their own version of the questionnaire to suit their needs. The CLEFT-Q measures 3 overarching domains: Appearance, Facial Function, and Quality of Life. The conceptual framework shown below was developed from qualitative interviews with 138 patients from 6 countries, 69 cognitive interviews, and careful examination of the research literature and engagement with 44 clinical experts. The CLEFT-Q was then field-tested in an international sample of 2434 patients in 12 countries.

APPEARANCE

The CLEFT-Q includes 7 appearance scales that measures aspects of appearance that are addressed by cleft-specific treatments including the face overall, lips, jaw, nose, nostrils, teeth and cleft lip scar.

FACIAL FUNCTION

The CLEFT-Q includes a speech scale that asks about problems with speaking such as having trouble with some words or sentences and having to speak slowly or to repeat oneself. The CLEFT-Q also includes a checklist to measure eating and drinking problems, such as having food get stuck in a hole in the mouth.

QUALITY OF LIFE

The CLEFT-Q includes 4 quality of life scales that measure psychological, social and school function. There is also a speech distress scale that measures feelings (e.g., embarrassment, frustration, being upset) associated with a speech problem.
