The primary aims of this paper were to reexamine the factor structure of the 21-item Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS), a measure of Food and Alcohol Disturbance (FAD), and investigate an alternative scoring structure. FAD is the use of disordered eating behaviors within an alcohol use episode to compensate for alcohol-related calories and/or increase effects of alcohol. The new scoring approach captures FAD behaviors based on whether they occurred before, during, or after alcohol use.
Participants were 586 young adults (18-30 years; 77.6% female; 55.8% non-Hispanic White) who completed online questionnaires on alcohol use, disordered eating behaviors, and FAD.
Confirmatory factor analyses did not provide unequivocal evidence for any previously proposed factor structures of the CEBRACS. Exploratory factor analysis suggested items capturing FAD "Before" drinking had a two-factor structure (i.e., Alcohol Effects and Compensatory Behaviors), items capturing FAD "During" drinking had a three-factor structure (i.e., Alcohol Effects, Diet & Exercise, and Extreme Weight Control Behaviors [EWCB]), and items capturing FAD "After" drinking had a two-factor structure (i.e., Diet & Exercise & EWCB).
The CEBRACS factor structure is not consistent across samples; however, despite suboptimal fit, the original structure remains the best approach to capture FAD behaviors. The alternative scoring reflects FAD behaviors based on when they occur relative to alcohol use. The two scoring approaches provide researchers and clinicians flexibility to describe FAD behaviors in multiple ways using the CEBRACS.
本文的主要目的是重新检验 21 项补偿性饮酒和酒精消费反应行为量表(CEBRACS)的因子结构,该量表是衡量食物和酒精紊乱(FAD)的一种方法,并研究一种替代评分结构。FAD 是指在饮酒过程中使用不规律的饮食行为来补偿酒精相关的卡路里和/或增加酒精的效果。新的评分方法基于行为是发生在饮酒之前、期间还是之后,来捕捉 FAD 行为。
参与者为 586 名年轻成年人(18-30 岁;77.6%为女性;55.8%为非西班牙裔白人),他们在线完成了关于饮酒、饮食失调行为和 FAD 的问卷。
验证性因子分析并没有为 CEBRACS 的任何先前提出的因子结构提供明确的证据。探索性因子分析表明,捕捉饮酒前 FAD 的项目具有两因子结构(即酒精效应和补偿行为),捕捉饮酒中 FAD 的项目具有三因子结构(即酒精效应、饮食和运动以及极端体重控制行为 [EWCB]),捕捉饮酒后 FAD 的项目具有两因子结构(即饮食和运动以及 EWCB)。
CEBRACS 的因子结构在不同样本中不一致;然而,尽管拟合度不理想,但原始结构仍然是捕捉 FAD 行为的最佳方法。替代评分反映了基于行为相对于饮酒发生的时间的 FAD 行为。这两种评分方法为研究人员和临床医生提供了灵活性,使用 CEBRACS 以多种方式描述 FAD 行为。
