The Bulimia Test-Revised (BULIT-R) is a measure of bulimia nervosa and binge eating disorder symptoms. While this measure can serve as a useful screening tool, the validity of the BULIT-R in White and Latina samples is uncertain. Previous research has proposed several different BULIT-R factor structures, but has yet to find consistent support for a measurement model or to test measurement invariance. To address this gap, the current study attempted to examine the factor structure and measurement invariance of the BULIT-R among 699 non-clinical White (40.9%) and Latina (59.1%) undergraduate women. Analyses indicated that none of the previously published factor structures in adult samples of the BULIT-R were an acceptable fit in either Latina or White undergraduates. These findings further underscore difficulties in replicating the BULIT-R factor structure, even when using similar sample characteristics to those in the literature. Given the lack of an adequate fitting measurement model, tests of measurement invariance were not conducted. In the absence of measurement invariance of the BULIT-R, there is uncertainty regarding group comparisons, such as whether group differences reflect true differences or are artifacts of measurement error. This study highlights the need for additional psychometric investigation of the BULIT-R. The focus should be on diverse groups as well as non-clinical samples, with the latter being less likely to endorse extreme eating behaviors. Special consideration should be given to the number of items included in the measurement model and the number of indicators per latent factor. Caution should be exercised when interpreting scores on this instrument.

修订的贪食症测试（BULIT-R）是神经性贪食症和暴饮暴食症症状的量度。尽管此措施可以用作有用的筛选工具，但BULIT-R在白人和拉丁裔样本中的有效性尚不确定。先前的研究提出了几种不同的BULIT-R因子结构，但尚未找到对测量模型的一致支持或测试测量不变性。为了弥补这一差距，当前的研究试图检查699名非临床白人（40.9％）和拉丁裔（59.1％）本科生女性中BULIT-R的因素结构和测量不变性。分析表明，在BULIT-R的成人样品中，先前发表的因子结构均不符合任何一种标准拉丁裔或白人大学生。这些发现进一步强调了复制BULIT-R因子结构的困难，即使使用与文献中相似的样品特征也是如此。由于缺乏适当的拟合测量模型，因此未进行测量不变性的测试。在没有BULIT-R的测量不变性的情况下，有关组比较的不确定性，例如组差异是否反映了真实差异或是测量误差的假象。这项研究强调了对BULIT-R进行其他心理测量研究的必要性。重点应该放在不同的人群以及非临床样本上，非临床样本不太可能认可极端饮食行为。应特别考虑测量模型中包含的项目数和每个潜在因子的指标数。解释本乐器上的乐谱时应格外小心。
