Cross-cultural adaptation of an implementation science glossary into simplified Chinese: study protocol

Introduction: Implementation science (IS) relies on standardized terminology, yet existing glossaries are largely English and Western-centric, creating risks of misinterpretation in other contexts. In China, with over one billion Chinese speakers and a rapidly expanding IS community, the absence of a unified glossary hinders training and knowledge exchange. We report a prospective, multi-stage cultural and linguistic adaptation study of the Implementation Science Research Glossary produced by the Centre for Implementation Science at King's College London, UK, from its original English version into Simplified Chinese. Methods: as ≥80% agreement on each term and definition (5) evaluation of the refined glossary through two complementary quantitative validation procedures: (a) content validation by 6-10 eligible faculty members using the Content Validity Index (CVI), and (b) response process validation by 10-30 Chinese-speaking postgraduate students using the Face Validity Index (FVI); items will be considered acceptable if I-CVI ≥0.83 and glossary-level S-CVI/Ave ≥0.90 for content validity, and I-FVI ≥0.80 with glossary-level S-FVI/Ave ≥0.90 for face validity; and (6) final expert panel review to reach consensus on the adapted glossary. Ethical approval will be obtained prior to data collection. Discussion: The study will produce the first, to our knowledge, culturally and linguistically adapted IS glossary for Chinese-speaking contexts. This resource is expected to enhance clarity and accessibility of implementation concepts, supporting research and practice in local settings. The documented adaptation process will provide a methodological reference for future translation of IS resources in other languages.
