Summary
The Japanese version of the Recap of atopic eczema (RECAP) has been linguistically validated for atopic dermatitis trials. This core outcome measure is now available for use in Japan.
Area of Science:
- Dermatology
- Psychometrics
- Health Outcomes Research
Context:
- Atopic dermatitis is a common skin condition requiring reliable outcome measures.
- The Recap of atopic eczema (RECAP) is a crucial core outcome measure for clinical trials.
- Cross-cultural adaptation of outcome measures is essential for global research.
Purpose:
- To translate and linguistically validate the Recap of atopic eczema (RECAP) into Japanese.
- To ensure the Japanese version of RECAP is understandable, relevant, and comprehensive for patients and clinicians in Japan.
- To facilitate the use of a standardized outcome measure in Japanese atopic dermatitis trials.
Summary:
- The RECAP was translated into Japanese following ISPOR and scale translation guidelines.
- Linguistic validation involved forward and back translations, expert review, and cognitive debriefing with 27 specialists, 10 adult patients, and 10 parents.
- The Japanese RECAP was deemed linguistically equivalent, understandable, comprehensive, and relevant, with minor modifications approved by original authors.
Impact:
- Provides a validated Japanese version of the RECAP for atopic dermatitis research.
- Enables consistent and comparable data collection in Japanese clinical trials.
- Supports the accurate assessment of treatment efficacy and patient experience in Japan.
