Development and validation of a questionnaire for diagnosing atopic dermatitis

Area of Science:

• Dermatology
• Epidemiology
• Public Health

Background:

• Atopic dermatitis (eczema) prevalence necessitates reliable population survey tools.
• Existing questionnaires require adaptation and validation for specific populations.
• Accurate diagnostic instruments are crucial for epidemiological research.

Purpose of the Study:

• To develop and validate a Danish questionnaire for atopic dermatitis suitable for population surveys.
• To assess the sensitivity and specificity of the developed questionnaire against a clinical validator.
• To incorporate a severity score for comprehensive atopic dermatitis assessment.

Main Methods:

• Adaptation of the UK Working Party's questionnaire for Danish children (ages 3-14).
• Recruitment of 61 children from clinical and community settings.
• Validation by a clinical expert assessing current or previous atopic dermatitis.

Main Results:

• The developed Danish questionnaire showed high sensitivity (90%) and specificity (97%) in diagnosing current atopic dermatitis.
• The questionnaire includes a valuable severity score.
• The natural course of atopic dermatitis presents challenges in validating instruments.

Conclusions:

• The Danish atopic dermatitis questionnaire is a validated and sensitive tool for population surveys.
• The inclusion of a severity score enhances its utility.
• Future studies should integrate history, current symptoms, findings, and severity scores for robust atopic dermatitis research.
