STRONG PSYCHOMETRIC PERFORMANCE
Rigorously developed and sensitive to clinical change

CONCEPT-DRIVEN APPROACH

The ACNE-Q was developed from 21 concept elicitation interviews with adolescent and adults with acne and acne scars, and input from 16 clinical experts from 5 countries. The ACNE-Q was then field-tested in a sample of 256 participants aged 12 and older from Canada and the USA.

MODULAR DESIGN

The ACNE-Q has 7 independently functioning scales that measure appearance (of facial, back and chest acne, skin and acne scars), acne-related symptoms and appearance-related distress. 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

Field-test sample included 256 adolescents and adults with acne and acne scars.

Industry

Used in international clinical trials of treatments for acne and acne scars.

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

ACNE-Q represents the first rigorously developed acne-specific patient-reported outcome measure to provide a set of scales for patients to report how their skin, acne (facial, back, and chest) and acne scars look. These concepts are important to include in clinical trials of treatments to improve or clear acne, to prevent and improve acne scarring, or to prevent future outbreaks. The ACNE-Q conceptual framework covers 3 concepts within 2 top-level domains. These concepts are measured via 7 independently functioning scales. Clinicians and researchers are able to administer the subset of scales relevant to their situation.

APPEARANCE

Five scales measure how someone’s acne (face, chest, back), acne scars, and facial skin look. Example items ask the amount of acne, how noticeable it is, and how the acne looks in scenarios, such as in photos, from the side (profile), or under a bright light.

ACNE-SPECIFIC SYMPTOMS

The ACNE-Q includes a short scale that measures how bothered someone is by acne-specific symptoms (e.g., itchy, hurts, feels uncomfortable).

APPEARANCE-RELATED DISTRESS

In clinical trials of treatments for acne and acne scars, appearance-related distress is an important outcome. The ACNE-Q includes a scale that measures how often someone behaves (e.g., cover up or hide, avoid going out) and feels (e.g., unhappy, self-conscious) a certain way about how they look.
