The Alliance Negotiation Scale – Therapist Version: Psychometric properties in a sample of Portuguese psychologists

The transtheoretical conceptualization of the working alliance and the resultant evaluation tools often overestimate the collaboration between therapist and client, while neglecting the negotiation process. The degree to which therapists and clients can negotiate disagreements regarding goals and tasks is an important indicator in establishing and maintaining the alliance. Even though the negotiation concept is not new, there is still a lack of reliable and parsimonious self-report measures of the construct. The purpose of this study was to translate, execute the cultural adaptation and, also, to perform a preliminary psychometric analysis of the Portuguese form of the therapist version of the Alliance Negotiation Scale (ANS-T_Pt).
