Abstract
Evidence-Based Psychology would be incomplete if the role of the therapeutic relationship was not investigated. However, the absence of adapted instruments impedes the development of empirical studies in the local context. The principal objective of this work was to adapt the patient version of the Revised Helping Alliance Questionnaire (HAq-II). As an additional objective a comparison of three theoretical models of therapeutic alliance was carried out. After translating the items and evaluating their equivalency via a panel of experts, the HAq-II was administered to a sample of 119 participants undergoing brief psychotherapy. The results of the confirmatory factorial analysis suggest an underlying model of two dimensions: positive bond with the therapist (α = .70) and goal and task agreement (α = .71). It should be noted that this model fits coherently with the theories proposed by Luborsky and Bordin.
