Can be used in research studies and clinical trials to study different approaches to treatments.
The NAIL-Q was developed from information provided by 23 people with 10 different nail conditions who took part in concept elicitation interviews. We also received input from 11 dermatologists. The NAIL-Q was then field-tested in an online international sample of 555 people with fingernail and toenail conditions.
The NAIL-Q includes 7 independently functioning scales measuring 3 domains. The variety of scales provides flexibility to choose the subset of scales best suited to measure the outcomes of interest in any given study or clinical situation.
Advancing Knowledge &
Improving Health Outcomes
Carefully designed to meet the requirements of regulatory bodies.
Can be used to benchmark outcomes in quality improvement initiatives.
Designed using a modern psychometric approach to facilitate use in patient care.
The NAIL-Q is a rigorously developed patient-reported outcome measure that can be used with all types of toenail and fingernail conditions. The NAIL-Q measures 3 overarching domains. Each domain includes 1 or more independently functioning scales. Clinicians and researchers are able to administer the subset of scales relevant to their situation.
This domain includes a scale to measure satisfaction with nail appearance and is relevant to anyone with any type of toenail or fingernail condition.
HEALTH-RELATED QUALITY OF LIFE
Four scales measure health-related quality of life. The scales cover symptoms, nail-related distress, the impact of a toenail condition on mobility, the impact of a fingernail condition on hand function, and fingernail strength.
This domain includes a scale to measure satisfaction with the outcome of nail treatment.
