Translation, transcultural adaptation, and validation of two questionnaires on shared decision making

OBJECTIVE: To translate, transcultural adapt, and validate the “CollaboRATE” measure and the “Ask 3 Questions” intervention in Argentina, allowing us to quantify the degree of use and implementation of shared decision making (SDM). DESIGN: Cross‐sectional study. SETTING AND PARTICIPANTS: Data were collected in an academic hospital in Buenos Aires. Physician–patient pairs were invited to participate following their scheduled outpatient visits. MEASUREMENTS: Two processes were carried out as follows: (a) The translation and transcultural adaptation process, in which translations were produced and then adapted to Spanish. (b) The validation process, in which questionnaires were completed by patient–physician pairs, the results of which were subsequently analysed. Reliability (Cronbach's alpha) and construct validity (principal component analysis) were assessed. RESULTS: The final Spanish versions of “CollaboRATE” and “Ask 3 Questions” were tested in a primary care sample of 56 participants. Both instruments presented adequate reliability and validity. Internal consistency yielded a Cronbach's alpha of 98.3 for the “CollaboRATE” measure and 0.77 and 0.69 for the patients and physicians versions of the “Ask 3 Questions” intervention. Principal components analysis showed eigenvalues of first component >1. DISCUSSION AND CONCLUSIONS: We obtained valid and reliable Spanish versions of the “CollaboRATE” measure and the “Ask 3 Questions” intervention. These versions can be used for the assessment of SDM in clinical visits, and to obtain new information which could help the monitoring of its implementation.
