Translation of the working alliance inventory short revised into Italian using a Delphi procedure and a forward-backward translation.

Introduction: Enhancing treatment adherence, especially for chronic diseases, can be achieved through therapeutic alliance, potentially elevating the quality of care. An instrument to evaluate the therapeutic alliance could be beneficial in routine clinical settings, educational environments, and extensive research efforts at national and European levels. In this study, we translated therapist and patient versions of the Working Alliance Inventory Short Revised (WAI-SR) into Italian.
