The aim of the current study was to design and evaluate a therapist version of the Alliance Negotiation Scale. The ANS was created in order to operationalize the construct of dyadic negotiation in psychotherapy and to augment existing conceptualizations of the working alliance.The ANS has existed only as a client self-report form since its inception and has demonstrated promise as a psychotherapy process measure. This research intended to develop a complementary therapist self-report version of the measure. The scale creation process is discussed in detail, and the results of a preliminary psychometric investigation are reported. The ANS-Therapist version (ANS-T) was developed using a sample of therapists (n = 114) through a principal components analysis procedure. The ANS-T contains nine unidimensional items andwas moderately correlated with therapist-reported working alliance (r = .468). The results of the study support the composition of the ANS-T and provide initial support for the reliability and validity of the measure.
