Food cravings play an important role in the neurobiology of appetitive behavior, being positively associated with negative feelings, eating disorders, and obesity. This study aimed to assess the psychometric properties of the Brazilian Food Cravings Questionnaire-Trait-reduced (FCQ-T-r), a short version of the most widely used measure of this behavior.
Undergraduate students (n=505) completed the full version of the FCQ-T and the Three-Factor Eating Questionnaire. Respondents' height and weight were also measured. Exploratory factor analyses were performed.
The FCQ-T-r exhibited a single-factor structure and satisfactory internal consistency (α > 0.80). A positive correlation was observed between FCQ-T-r scores and those of the original version. Furthermore, FCQ-T-r scores correlated positively with uncontrolled eating and emotional eating behaviors. No correlation was found between body mass index and FCQ-T-r scores. Considering our sample characteristics, we suggested specific FCQ-T-r cutoff points for males and females in the Brazilian population.
Our results support the structure of the Brazilian adaptation of the FCQ-T-r, which seems to be a viable instrument to investigate food cravings, particularly in time-constrained settings. Further studies are needed to verify these findings in other age ranges and clinical samples.
食物渴望在食欲行为的神经生物学中起着重要作用，与负面情绪、饮食失调和肥胖呈正相关。本研究旨在评估巴西食物渴望问卷特质简化版（FCQ-T-r）的心理测量特性，这是该行为最广泛使用的测量方法的简短版本。
本科生（n=505）完成了 FCQ-T 完整版和三因素饮食问卷。还测量了受访者的身高和体重。进行了探索性因素分析。
FCQ-T-r 呈现出单一因素结构和令人满意的内部一致性（α>0.80）。FCQ-T-r 得分与原始版本的得分呈正相关。此外，FCQ-T-r 得分与失控饮食和情绪性饮食行为呈正相关。体重指数与 FCQ-T-r 得分之间无相关性。考虑到我们的样本特征，我们建议在巴西人群中为男性和女性设定特定的 FCQ-T-r 截断值。
我们的结果支持巴西版 FCQ-T-r 的结构，它似乎是一种可行的工具，可以研究食物渴望，特别是在时间受限的情况下。需要进一步的研究来验证这些发现是否适用于其他年龄范围和临床样本。
