The Bulimia Test-Revised (BULIT-R): Psychometric properties in a non-clinical sample of White and Latina college women.

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.
