The Outcome Questionnaire (OQ-45) is an instrument designed to measure client's progress in therapy, repeatedly, during psychotherapy. It is not a theoretically oriented, and can be applied to psychotherapy of different theoretical approaches. It shows evidence of validity and internal consistency, in its original version. The aim of this work was to translate and culturally adapt the OQ-45 to the context of Brazilian culture. The process consists of five stages: translation, synthesis, back-translation, review by experts and pre-test. It was based on two versions: the original, in English and the Portuguese. The results suggest that the OQ-45 is an easy test to understand and to apply, even in people with low educational level. Validity and reliability studies will be needed for the Brazilian version, comparing clinical with non-clinical samples.
