Abstract
The Leeds Food Preference Questionnaire (LFPQ) is a computerised procedure that assesses liking, wanting and relative preferences for shared characteristics of food. This study adapted the LFPQ (LFPQ-A) to assess its cross-cultural validity in an Arab sample by examining its performance for food characteristics of fat (high or low) and taste (sweet or nonsweet), under fasted and fed states. Individual differences in eating behaviour were examined by testing for associations between the LFPQ-A outcomes and subscales of the Three Factor Eating Questionnaire (TFEQ). Thirty healthy males (age: 36.3±10.0 years; body mass index: 29.7±5.3 kg/m2) participated in the study. All participants attended the laboratory in the morning following an overnight fast, and performed the LFPQ-A under fasted and fed conditions (after a standardised test meal). Results showed that implicit wanting and relative preference for non-sweet foods decreased in the fed compared to the fasted state, whereas scores for sweet foods increased. Explicit liking and explicit wanting were also higher for non-sweet foods in the fasted condition, and decreased to a greater extent in the fed condition compared to a lesser decrease for sweet foods. Scores on all LFPQ-A outcomes for high-fat non-sweet foods were positively associated with TFEQ Disinhibition. Outcome scores for low-fat non-sweet foods were positively associated with TFEQ Restraint. The LFPQ-A showed outcomes that were consistent with studies performed in Western samples, therefore the current study helps to confirm the validity of the LFPQ-A as a measurement of liking and wanting and preference for food among Arabs.
