SHORT INDEPENDENTLY FUNCTIONING SCALES

MEASURING WHAT MATTERS TO PATIENTS

DESIGNED FOR ANY NAIL CONDITION

STRONG PSYCHOMETRIC PERFORMANCE

CONCEPT-DRIVEN APPROACH

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.

MODULAR DESIGN

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

Research

Can be used in research studies and clinical trials to study different approaches to treatments.

Industry

Carefully designed to meet the requirements of regulatory bodies.

Benchmarking

Can be used to benchmark outcomes in quality improvement initiatives.

Patient Care

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

Scale Structure

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.

NAIL APPEARANCE

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.

TREATMENT

This domain includes a scale to measure satisfaction with the outcome of nail treatment.
