Propriedades psicométricas da versão brasileira do Questionário de Ambivalência em Psicoterapia (QAP)

Abstract

The study of factors that impede behavioral change has been receiving increasing attention from researchers, since their understanding provides important indicators for increasing the effectiveness of psychotherapy. Several studies have shown that levels of resistance and ambivalence are associated with poorer therapeutic outcomes and early cessation of therapy. The purpose of this study is to perform the cross-cultural adaptation to Brazil and to evaluate the psychometric properties of the Ambulance Questionnaire in Psychotherapy (QAP) for individuals undergoing psychotherapeutic treatment. We interviewed 181 individuals in a therapeutic process in Clinics School of Psychology courses and private practices of Juiz de Fora and region using a criterion of convenience. The QAP showed a low correlation with URICA and its subscales. The structure of the QAP items consists of two factors that explain 61.19% of the total variance. In the internal consistency analysis, the Cronbach's alpha value of the instrument was 0.86. The QAP and OQ-45 had a moderate positive correlation. The Brazilian version of the QAP proved to be an adequate instrument, quick and easy to apply, with good psychrometric properties
