Mixed Rasch Modeling of the Self-Rating Depression Scale: Incorporating Latent Class and Rasch Rating Scale Models

In this study, mixed Rasch modeling was used on the Self-Rating Depression Scale (SDS), a widely used measure of depression, among a non-Western sample of 618 Korean college students. The results revealed three latent classes and confirmed the unidimensionality of the SDS. In addition, there was a significant effect for gender in terms of class membership. The implications for diagnosis and treatment for normal populations are discussed as well as the differences in depression profiles of those in Western and non-Western samples.
