Purpose: To present a brief report of the first steps that involved the process of the cultural translation and adaptation of the Expressive One-Word Picture Vocabulary Test, fourth edition to Brazilian Portuguese (BP). Methods: The process of translation and adaptation of this instrument was performed in the following steps: (1) translation of the original text (English) to Brazilian Portuguese (target culture) by two different sworn translators oriented towards our research goal; (2) parity analysis between both translations and design, by a group of experts, of a synthesis version; (3) back translation of the synthesis version by two other sworn translators who did not participate in step 1; and (4) Comparison between back-translation and the original version made by a group of specialists, thus shaping the pre-final adapted version of the EOWPVT-4. Results: In the Brazilian version, the number of items from the original version was maintained and the cultural adaptation of the EOWPVT-4 to BP followed the steps recommended in the literature besides considering the differences in the socio-cultural context, showing no significant discrepancies regarding semantic equivalence. Relevant adaptations (e.g., items not representative within the Brazilian culture) were required during this process so that the instrument could be used with the same methodological rigor as the original instrument. Conclusion: The process of cultural adaptation of this instrument indicated that there was theoretical, semantic, idiomatic and cultural equivalence with the original version in English.
