Clinical Trial Summary

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.


Description:

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.

Assessment of the validity of the ES-LFPQ: Each participant will complete the ES-LFPQ in before (fasted state) and after a standardized meal (fed state). Evaluation of the reproducibility of the ES-LFPQ: With at least one week of difference between tests, each participant will repeat the same protocol performed in the previous visit and under the same conditions.

Outcome

Type Measure Description Time frame Safety issue
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
