Fasting Clinical Trial
— ES-LFPQOfficial title:
Development of the Leeds Food Preference Questionnaire in Spanish: Sensitivity and Reproducibility of Liking and Wanting for Food in Fasted and Fed States
The Leeds Food Preference Questionnaire (LFPQ) is a computer-based task used to measure reward responses and preferences for images of food. The present study aims to develop a Spanish version of the LFPQ (ES-LFPQ) by examining its validity and repeatability under fasted and fed states.

Primary | Explicit liking | The sensory pleasure elicited by contact with food. Measured with 0 to 100-mm visual analogue scale in response to the question "How pleasant would it be to taste some of this food now?" where 0 means "Not at all" and 100 means "Extremely" | 60 minutes | |
Primary | Explicit wanting | The motivation to consume a specific food manifesting explicitly (conscious and subjective). Measured with 0 to 100-mm visual analogue scale in response to the question "How much do you want some of this food now?" where 0 means "Not at all" and 100 means "Extremely" | 60 minutes | |
Primary | Implicit wanting | The motivation to consume a specific food manifesting implicitly (unconscious). Measured by punctuation on questionnaire ES-LFPQ. The score assigned to a specific food category based on a forced choice between pairs of food options and taking into account reaction time, in response to the question "Which food do you desire to consume the most at present?". A positive score indicates a greater preference for a given food category relative to the alternatives in the task and a negative score indicates the opposite. A score of zero would indicate that the category is equally preferred. | 60 minutes | |
Primary | Relative preference | The preference of a food in comparison with another food. Measured by punctuation on questionnaire ES-LFPQ. The score assigned to a specific food category based on a forced choice between pairs of food options in response to the question "Which food do you desire to consume the most at present?". A positive score indicates a greater preference for a given food category relative to the alternatives in the task and a negative score indicates the opposite. A score of zero would indicate that the category is equally preferred. | 60 minutes | |
Primary | Fat appeal bias | Bias scores for food fat content (high or low) computed by subtracting the mean low-fat scores from the mean high-fat scores. Positive values indicate a preference for high-fat, negative values indicate a preference for low fat and a score of 0 indicates an equal preference between fat content. | 60 minutes | |
Primary | Taste appeal bias | Bias scores for food taste (savoury or sweet) computed by subtracting the mean savoury scores from the mean sweet scores. Positive values indicate a preference for sweet foods, negative values indicate a preference for savoury foods and a score of 0 indicates an equal preference between taste categories | 60 minutes | |
Secondary | Hunger | The subjective sensation described as the primary motivation to eat. Measured with 0 to 100-mm visual analogue scale in response to the question "How hungry do you feel now?" where 0 means "Not at all" and 100 means "Extremely" | 60 minutes | |
Secondary | Fullness | The degree of satisfaction and/or fullness following food consumption. Measured with 0 to 100-mm visual analogue scale in response to the question "How full do you feel now?" where 0 means "Not at all" and 100 means "Extremely" | 60 minutes |
