Measures of beliefs and attitudes toward food have generally been limited to the measurement of more pathological eating attitudes (e.g., disordered eating). The Food Life Questionnaire (FLQ) and its short form (FLQ-SF) were developed to examine attitudes toward a broader range of foods: however, the factor structure of the FLQ-SF was not confirmed in any study with young women. In the present study, we performed a psychometric evaluation of the Brazilian Portuguese translation of the FLQ-SF in a sample of 604 women. We evaluated the factor structure using a two-step, split-sample exploratory and confirmatory factor analytic approach. Results supported a four-factor structure (i.e., weight concern, diet&ndash:health orientation, belief in a diet&ndash:health linkage, and food and pleasure) with 18 items (&chi:2/df = 2.09: CFI = 0.95: TLI = 0.94: RMSEA = 0.05 (90% CI = 0.04: 0.06: p >: 0.05): and SRMR = 0.08). Additionally, we found good internal consistency for all FLQ-SF subscales (McDonald&rsquo:s &omega: = 0.79&ndash:0.89) and convergent validity with measures of feelings, beliefs, and behaviors involved in food attitudes. Collectively, these results support the use of the FLQ-SF in Brazilian women and provide a foundation to expand the literature on beliefs and attitudes toward food in this population.
