Cross-cultural adaptation of the State and Trait Food Cravings Questionnaires ( FCQ-S and FCQ-T) into Portuguese

Abstract

This study aimed to present the cross-cultural adaptation of the State and Trait Food Cravings Questionnaires (FCQ-S and FCQ-T) into Portuguese. Tools were translated and back-translated, field experts evaluated the conceptual, operational and item-based equivalence and a sample of students assessed tools, evaluating the level of understanding and analyzing internal consistency through Cronbach's coefficient. In addition, the semantic equivalence was assessed though the intraclass correlation coefficient between the bilingual scores in each question of both versions (English and Portuguese). Tools were considered easy to understand (experts scored 95.4% and 97% for the FCQ-T and FCQ-S, respectively, and 81.8% of students considered them easy to understand), and showed satisfactory internal consistency values (FCQ-T ranged from 0.6 to 0.8 and FCQ-S ranged from 0.5 to 0.8). From the cross-cultural adaptation process, the satisfactory results enable the recommendation of the Brazilian version of FCQs.
