COPD Exacerbation Recognition Tool: Translation, Linguistic, and Cross-Cultural Validation

Area of Science:

• Pulmonary Medicine
• Linguistic Validation
• Cross-Cultural Health Research

Background:

• The Chronic Obstructive Pulmonary Disease (COPD) Exacerbation Recognition Tool (CERT) was created to enhance patient ability in recognizing COPD exacerbations.
• A validation study focused on the cross-cultural and linguistic accuracy of 46 CERT translations spanning 25 countries and 6 continents.

Purpose of the Study:

• To conduct a cross-cultural and linguistic validation of 46 translated versions of the CERT.
• To ensure the tool's understandability and cultural relevance for diverse patient populations globally.

Main Methods:

• Utilized a certified ISO-17100 methodology involving dual forward translations, reconciliation, and independent back-translations.
• Conducted cognitive debriefing interviews with at least five native COPD patients per language.
• Assessed the cultural representativeness of region-specific images through patient review and iterative amendments.

Main Results:

• Translations demonstrated conceptual equivalence to the original CERT and achieved harmonization across languages.
• COPD patients found the CERT easy to understand and use.
• Images were confirmed as representative across diverse cultures, countries, and religions.

Conclusions:

• The patient-centric approach to CERT translation ensures ease of understanding and validity across diverse linguistic and cultural groups.
• The validated CERT translations are suitable for global use in improving COPD exacerbation recognition.
