There is a lack of Brazilian questionnaires to assess physical activity in children. The Physical Activity Checklist Interview (PACI) was originally developed for North American children and allows assessing physical activity during the previous day. The objectives of this study were: i) to describe procedures for choosing the PACI for cross-cultural adaptation and ii) to assess conceptual, item, and semantic equivalence of the Brazilian version to be used with 7-to-10-year-old children. PACI was identified from a systematic review of 18 questionnaires. The process of choosing the instrument involved discussions with researchers. The PACI allows assessing the construct and its dimensions. Some kinds of physical activity that are uncommon in the Brazilian population had to be eliminated. The following steps were taken to evaluate semantic equivalence: translation, retranslation, connotative and referential meaning assessment, and a pretest with 24 children aged 7 to 10 years. We present the PACI in its Brazilian adapted version, called Lista de Atividades Físicas (LAF).
