Abstract
High levels of ambivalence are associated with poor outcomes and therapeutic abandonment. The objective of this study was to conduct a cross-cultural adaptation and assessment of the psychometric properties of the Ambivalence in Psychotherapy Questionnaire (APQ). After cultural adaptation of the instrument, we assessed 181 individuals undergoing psychotherapy of different approaches in school clinics and private practices. The APQ was validated regarding internal structure and relationship with external variables. In the confirmatory factor analysis, the model with the best fit was composed of three dimensions: two first-order - Demoralization and Wavering - and one second-order - Ambivalence. The internal consistency was 0.86. In relation to external variables, the APQ correlated moderately with measures of psychological distress (OQ-45- Outcome Questionnaire) (r = 0.65) and motivation to change (URICA- University of Rhode Island Change Assessment): contemplation (r = 0.36) and maintenance (r = 0.37). The results indicated that the Brazilian version of the APQ is a suitable instrument, of quick and easy application.
