AB  - Introduction: The computerized Leeds Food Preference Questionnaire measures liking and wanting for food images as separable components of food reward. We aimed to validate a German version of this instrument (LFPQ-G). Methods: LFPQ-G-development included a standardized production of culturally adapted food images representing four food categories varying in fat (high vs. low) and taste (sweet vs. savory). The LFPQ-G was validated in 59 mostly female (69.5 %), on average normal weight participants with a median BMI of 23.2 kg/m2 [21.3 kg/m2; 26.3 kg/m2], aged between 21 and 65 years, who completed the LFPQ-G in a fasted state and after a test meal. Repeated measure ANOVA assessed changes in LFPQ-G outcome measures from a fasted to a fed state. The Three Factor Eating Questionnaire (TFEQ) was applied to assess associations between LFPQ-G outcome measures and individual differences in eating behavior. Results: Explicit liking and wanting for food in general decreased from pre to post meal (p < 0.001). Significant two-way-interactions revealed greater explicit liking and wanting and implicit wanting for savory over sweet foods in the fasted condition, while opposite in the fed state (p < 0.001). Implicit wanting and explicit wanting and liking were greater for low- than for high-fat foods (p < 0.001). Conclusion: Outcome measures of the new LFPQ-G are sensitive to changes in satiety and identify changes in taste preference following a test meal as described in previous studies, indicating valid assessment of different aspects of food reward.
