TRANSLATION, CROSS-CULTURAL ADAPTATION AND VALIDATION OF TWO QUESTIONNAIRES ABOUT SHARED DECISION MAKING (SDM)

Introduction and Objectives Shared decision making (SDM) is a process where health professionals and patients work together to make health decisions. There is a growing interest in the development of SDM measurement tools. The Health Foundation (HF - UK) developed an instrument to evaluate SDM from two perspectives (user and health provider). Elwyn et al also created a questionnaire named ”CollaboRATE” The objectives of this study are to translate to argentinian spanish, to cross-cultural adapt and to validate these tools. Methods Study conducted at Hospital Italiano of Buenos Aires, Argentina. Patients were interviewed after an outpatient medical appointment, with a primary care provider or other physician. Translation and cross-cultural adaptation: Forward and back translations were performed by bilingual researchers. Following revision and conciliation of the versions, cognitive interviews were conducted. Later, the interviews were reviewed and the final version obtained. Validation:The sample was adequate with the Kaiser Meyer Olkin (KMO) index. Content validity was performed by experts. Factor Analysis was used to analyse construct validity. Internal consistency was evaluated through the Cronbach’s alpha coefficient. The instruments were validated using the hypothesis confirmation method. Results After the translation process, 56 interviews were conducted (more than 10 interviews per item). The KMO index values were 0,72 and 0,62 for the HF questionnaires, and 0,74 for the CollaboRATE. The Bartlett test was < 0.0001 for the three instruments. Cronbach’s alpha coefficient was 0.77-0.69 for the HF questionnaires Conclusion These are the first brief questionnaires available in argentinian spanish that allow measurement of SDM.
