SCAR-Q was field-tested with 731 surgical, traumatic and burn patients in 4 countries.
The SCAR-Q was developed from scar information provided by 52 children and 192 adults who took part in concept elicitation interviews to develop BREAST-Q, FACE-Q (aesthetic, head/neck cancer, skin cancer, and craniofacial), BODY-Q and CLEFT-Q. To establish content validity, we conducted cognitive interviews with 25 adults and 20 children with scars, and obtained input from 27 clinical experts. The SCAR-Q was then field-tested in a sample of 731 patients from 4 countries.
The SCAR-Q is for children and adults aged aged 8 years and older with any type of surgical, traumatic and/or burns scar. The SCAR-Q has 3 independently functioning scales that measure scar appearance, scar symptoms and psychosocial impact. One or more scales can be used depending on the outcomes of interest in any given study or clinical situation.
In clinical trials of treatments for scars, symptoms and psychosocial distress are important outcomes. But scar appearance is also important to patients. The SCAR-Q represents a rigorously developed patient-reported outcome measure that provides a comprehensive scar appearance scale, and 2 other scales that measure outcomes important to children and adults with scars. Clinicians and researchers are able to administer the specific scales relevant to their situation.
This scale measures scar appearance in terms of a range of characteristics of a scar, including the size, color, contour, visibility and how it looks in scenarios (e.g., up close).
This scale measures how bothered someone is by symptoms such as the scar feeling itchy, painful, tight, etc.
This scale measures the psychosocial impact of having a scar, including feeling self-conscious, unhappy or embarrassed about the scar and concealment behaviors.
