Translation of the Working Alliance Inventory Short Revised (WAI-SR) from English into Spanish, using a forward backward translation and a Delphi consensus method

Abstract : Background : The improvement of Therapeutic Alliance (TA) in medicine is an important lever to promote adherence to treatment and the quality of care. A research group at the Faculty of Medicine of Brest has been working on a TA assessment tool that can be used in everyday General Practice and for the training of medical students. A systematic literature review and a RAND/UCLA Appropriateness Method identified the Working Alliance Inventory Short Revised (WAI SR) as the most appropriate scale, according to its reliability and reproducibility, to evaluate TA. The purpose of this study was to translate into Spanish the WAI SR. Method: A forward and backward translation with a Delphi consensus method was used to ensure the transferability of the scale’s properties. A research team of 5 Spanish experts produced a forward translation of the WAI SR into Spanish. For this translation they took into account the cultural context and the possible future uses of the scale. Only one Delphi round was necessary to achieve a first translation. The experts of the Delphi round were Spanish general practitioners who had a good level in English. After achieving a consensus, a professional translator finalized a backward-translation, to assess the linguistic equivalence. Results: An adapted forward translation was achieved. 24 experts took part in the Delphi round. A final consensus was reached with one Delphi round. The backward translation was carried out by a professional translator who has lived in Spain for 7 years. Conclusion: A Spanish translation of the WAI SR is now available for medical research, daily practice of general practitioners and for medical students training. This translation is consistent with the original scale. A validation of its applied psychometric properties in General Practice field in Spain could strengthen the validation process in future research.
