A Method for Designing a Patient Burden Questionnaire in Dermatology

Area of Science:

• Dermatology
• Psychometrics
• Health Outcomes Research

Background:

• Disease burden is increasingly central to patient care evaluation, especially in dermatology.
• Patient-reported outcomes (PROs), including symptoms and disease burden, are valuable for assessing care.
• Standardized tools are needed to effectively measure disease burden in skin diseases.

Purpose of the Study:

• To present a validated methodology for developing and validating disease burden questionnaires specifically for patients with skin diseases.
• To provide a framework for consistent and reliable measurement of disease burden in dermatological conditions.

Main Methods:

• A standardized methodology was developed based on a review of 16 existing burden questionnaires published in the last decade.
• The methodology includes guidance on questionnaire conception, development, and validation processes.
• Key validation aspects covered are reliability, internal consistency, external validity, cognitive debriefing, test-retesting, and cross-cultural adaptation.

Main Results:

• A standardized methodology for the design and validation of disease burden questionnaires for chronic skin diseases is proposed.
• Detailed guidance is provided for all stages of questionnaire development and validation, including statistical analysis.
• The methodology aims to simplify and enhance the creation of reliable and valid burden assessment tools.

Conclusions:

• The proposed methodology improves the design and validation of disease burden questionnaires in dermatology.
• These validated questionnaires can be effectively utilized in both clinical research and routine clinical practice.
• Implementing this methodology can lead to more accurate assessments of patient well-being and treatment efficacy in skin diseases.
