A crucial problem in studies involving food cravings is the lack of a psychometrically sound measure for use among overweight and obese populations. The degree to which the Food Cravings Questionnaires-Trait (FCQ-T) and State (FCQ-S) evidenced acceptable psychometric properties among overweight and obese participants was assessed. In study 1, 109 participants completed the FCQ-T and FCQ-S. Item-total correlations, test-retest reliability, internal consistency, and factor structures were examined. Results indicate good internal consistency and partially support the factor structures. In study 2, the construct and predictive validity of the FCQ-S were examined. Twenty-eight women completed the FCQ-S 15 min after finishing a standardized breakfast and then twice more, 90 min apart. Subsequent ad libitum food intake was recorded. Results suggest that the FCQ-S is sensitive to state changes in food cravings, but that the magnitude of the changes was moderate. The FCQ-S was not a good predictor of subsequent food intake. The FCQ-T and FCQ-S may be useful in studies that examine triggers of and interventions for excessive food intake.
在涉及食物渴望的研究中,一个关键问题是缺乏一种在超重和肥胖人群中使用的心理测量学上可靠的测量方法。评估了食物渴望问卷-特质版(FCQ-T)和状态版(FCQ-S)在超重和肥胖参与者中表现出可接受心理测量学特性的程度。在研究1中,109名参与者完成了FCQ-T和FCQ-S。检验了项目-总分相关性、重测信度、内部一致性和因子结构。结果表明内部一致性良好,并部分支持因子结构。在研究2中,检验了FCQ-S的结构效度和预测效度。28名女性在吃完标准早餐15分钟后完成FCQ-S,然后在90分钟的间隔内再完成两次。记录随后的随意食物摄入量。结果表明,FCQ-S对食物渴望的状态变化敏感,但变化幅度适中。FCQ-S不是随后食物摄入量的良好预测指标。FCQ-T和FCQ-S可能在研究过度食物摄入的触发因素和干预措施中有用。
