The Leeds Food Preference Questionnaire (LFPQ) is a computer-based task for measuring reward responses (liking/wanting) and preferences for images of food. There are no cultural adaptation studies for the Spanish population to date in order to address its validity and repeatability in a test-retest design. The present study aim to develop a Spanish version of the LFPQ (ES-LFPQ), examine its outcomes under fasted and fed states; and test its reproducibility after one week.~An online survey containing foods that were either low-fat sweet, high-fat sweet, low-fat savoury or high-fat savoury was first conducted among a sample of 96 Spanish adults (60.4 % women) to develop and validate a culturally appropriate food image database. 50 participants (25 men and 25 women) will participate in two identical trials where they will completed the ES-LFPQ under fasted and fed states (immediately after a standardised meal), at least one week apart.
