The scientifi c method is indispensable for the consolidation of evidence-based Psychology. However, Psychology is a discipline permeated by doubts about its scientifi c nature, and there are resistances to the scientifi c method by its students and professionals. The aim of this study was to verify relations between Attitude towards Science in Psychology's scores (ATSP) and sociodemographic characteristics. Participants were 611 people, students or professionals of Psychology, from all regions of Brazil, with 18 to 75 years, 64.2% women. Participants answered a sociodemographic questionnaire and the Attitude towards Science in Psychology Scale. Men presented ATSP more favorable than women, as did students from private universities compared to public universities and people who work in relation to those who do not work. Rio de Janeiro presented lower rates of ATSP compared to other states in the South and Southeast. The results promote preliminary fi ndings of variables involved in the diffi culty of constructing a scientifi c psychology in Brazil.
