INTRODUCTION: In Brazil, psychotherapy research is in its early development; there are no systematic studies of the therapeutic process, and there are few available measurement instruments for researchers interested in this field. OBJECTIVE: To develop a Portuguese version of the Psychotherapy Process Q-Set. METHOD: The development of a Portuguese version of the Psychotherapy Process Q-Set involved four stages: translation, back translation, evaluation of semantic equivalence and discussion of the results by the authors. Five raters were trained to apply the instrument. During the training, a field diary was used to record difficulties identified in task execution and to subsidize complementary data. Thereafter, the Psychotherapy Process Q-Set was applied to seven sessions of a short-term psychodynamic psychotherapy to examine agreement between referees. RESULTS: The Portuguese version of the Psychotherapy Process Q-Set presented good semantic equivalence with the original. The assessment of interrater reliability had a satisfactory result. It is worth stressing that applying the Psychotherapy Process Q-Set requires study, time and reflection. The discussion with raters pointed to the need of reviewing the application manual concerning the clinical examples. This will be performed in the near future to minimize the discrepancies observed in the understanding of some concepts and to better adjust them to the Brazilian reality. CONCLUSION: This study provides a Portuguese version of the Psychotherapy Process Q-Set, a versatile instrument that can be used in different contexts to quantitatively describe the therapeutic process of different psychotherapies in clinically significant terms.
