Brief 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.

Conditions

Fasting; Fed

Outcome Measures

Primary Outcomes (6)

• 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

• 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

• 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

• 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

• 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

• 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

Study Arms (1)

Group 1

OTHER

Each participant will attend the laboratory twice to perform two identical trials in order to asses validity (first trial) and reproducibility (second trial)

Other: Standardized meal

Interventions

Standardized meal OTHER

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.

Group 1
