Validation of the French version of the ICHOM adult oral health standard set

Abstract

Introduction: The ICHOM Adult Oral Health Standard Set (AOHSS) recently developed by the ICHOM Oral Adult Health Working Group is a standard set of outcomes designed for its collection in clinical practice in dental health. The outcome standard set is made up of clinical-reported outcome measures (CROMs) and patient-reported outcome measures (PROMs). The purpose of this study was to translate and cross-culturally adapt the PROM section of the Standard Set in French for France to enable comprehensive evaluation of the patients' oral health quality of life in a French population. Methods: The questionnaire was translated following the guidelines of the International Society for Pharmacoeconomics and Outcome Research (ISPOR). We included patients consulting in a dentistry clinic (n = 127) and seeking dental care. The PROM and CROM data were collected from all patients. Both reliability and the internal consistency were evaluated. Results: The ICHOM AOHSS was successfully translated into French. We sampled and surveyed 126 patients in a dentistry clinic in France using the French translation of the ICHOM AOHSS. Cronbach's α was calculated to measure the internal consistency. The resulting Cronbach's α was 0.8, indicating acceptable homogeneity. Conclusions: The French version of the ICHOM AOHSS shows acceptable psychometric properties in terms of reliability and internal consistency. This translation is suitable for its implementation in a French-speaking patient population.
