Translation, cultural adaptation, and validation of the Hebrew version of the Leeds Food Preference Questionnaire

This is the authors' abstract. We don't add key points for this paper.

The Leeds Food Preference Questionnaire (LFPQ) is a computerized task assessing liking, wanting, and preferences for foods categorized by fat content and taste into four groups; high-fat savory (HFSA), low-fat savory (LFSA), high-fat sweet (HFSW), and low-fat sweet (LFSW). This study aimed to translate, culturally adapt, and validate a Hebrew LFPQ (LFPQ-He) version. The study included two phases. Phase one involved translating the task into Hebrew, selecting and photographing food images, and validating them among 153 participants from the general population (50 % women, mean age and BMI of 43.0 ± 14.3 years and 26.2 ± 4.8 kg/m 2 ). Phase two evaluated the psychometric properties of the LFPQ-He with 20 metabolic bariatric surgery candidates (70 % women, mean age and BMI of 43.8 ± 13.9 years and 44.5 ± 6.2 kg/m 2 ) and 39 healthy medical center employees (79.5 % women, mean age and BMI of 40.5 ± 10.0 years and 21.7 ± 1.9 kg/m 2 ). Data collection included demographics, anthropometrics, the Power of Food Scale (PFS), and the LFPQ-He task, which was re-completed by the medical center employees after a week. Convergent validity showed low to moderate positive correlations between the PFS total and its subscale score and HFSA-related variables, and low negative correlations with LFSW-related and LFSA-related variables. Known-group validity results were non-significant, but trends aligned with expected preferences. Test-retest reliability demonstrated intraclass correlation coefficients ranging from 0.451 (95 %CI: 0.153, 0.674) to 0.901 (95 %CI: 0.817, 0.948), reflecting moderate to good reliability. The LFPQ-He showed acceptable psychometric properties, supporting its use for assessing food preferences and hedonic food-reward in future studies. • LFPQ assesses liking, wanting, and food preferences by fat content and taste. • The Hebrew LFPQ was translated, adapted, and validated with new food images. • Hebrew LFPQ variables correlated with PFS scores, supporting convergent validity. • Test-retest reliability for the Hebrew LFPQ ranged from moderate to good. • Acceptable psychometric properties of the Hebrew LFPQ supporting its future use.
