在本研究中，多维特质和状态食物渴望量表（FCQ-T和FCQ-S），由Cepeda-Benito，Gleaves，威廉姆斯和Erath开发，[2000.国家和特徴食物渴望量表的开发和验证。Behavior Therapy，31，151-173]进行了修改，以构建一个指数的一般食物渴望，而不是具体的食物渴望。在三项独立的研究中，对修改后的问卷（更名为特质和状态一般食物渴望量表（G-FCQ-T和G-FCQ-S））的因素结构、效度和信度进行了研究。首先，进行探索性因子分析，得到具有四因子结构的G-FCQ-T，其与原始（九因子）FCQ-T相比显著缩短，以及因子结构与原始FCQ-S高度可比的G-FCQ-S。其次，为了复制研究1中发现的G-FCQ-T和G-FCQ-S的因子结构，进行了验证性因子分析。结果表明，这两个问卷都有足够的拟合。此外，两个版本的重测信度是令人满意的，结构效度的分析一般揭示了预期的结果。在研究3中，国家版本的G-FCQ的有效性进行了进一步研究，通过相关的分数在这个问卷上的指数的食物剥夺和饱。结果表明，G-FCQ-S确实测量食物渴望作为一个可变的状态，这是由情境和时间变量的影响。总的来说，可以得出结论，G-FCQ-T和G-FCQ-S都是可靠和有效的措施，一般特质和状态依赖的食物渴望。(c)2006爱思唯尔有限公司保留所有权利。
In the present study, the multidimensional Trait and State Food Cravings Questionnaires (FCQ-T and FCQ-S), as developed by Cepeda-Benito, Gleaves, Williams, and Erath, [2000. The development and validation of the State and Trait Food Cravings Questionnaires. Behavior Therapy, 31, 151-173], were modified in order to construct an index of general food craving instead of specific food craving. The factor structure, validity and reliability of the modified questionnaires, renamed as the Trait and State General Food Cravings Questionnaires (G-FCQ-T and G-FCQ-S), were investigated in three separate studies. Firstly, exploratory factor analyses were conducted, which yielded a G-FCQ-T with a four-factor structure, that was considerably shorter as compared to the original (nine-factor) FCQ-T, and a G-FCQ-S of which the factor structure was highly comparable to the original FCQ-S. Secondly, in an attempt to replicate the factor structures of the G-FCQ-T and the G-FCQ-S as found in Study 1, confirmative factor analyses were performed. Results indicated adequate fits for both questionnaires. In addition, the test-retest reliability of both versions was satisfactory and an analysis of the construct validity generally revealed the expected results. In Study 3, the validity of the state version of the G-FCQ was further investigated by relating scores on this questionnaire to indices of food deprivation and satiation. Results indicated that the G-FCQ-S indeed measures food craving as a variable state, which is influenced by situational and temporal variables. Altogether, it can be concluded that the G-FCQ-T and G-FCQ-S are both reliable and valid measures of general trait-like and state-dependent food craving. (c) 2006 Elsevier Ltd. All rights reserved.
