Structural Validity, Internal Consistency, and Rater Reliability of the Modified Barium Swallow Impairment Profile: Breaking Ground on a 52,726-Patient, Clinical Data Set.

This study leverages a large-scale, clinical data set to provide strong, generalizable evidence that the MBSImP assessment method has excellent structural validity and internal consistency. In addition, the results show that MBSImP-trained speech-language pathologists can demonstrate good interrater and intrarater reliability.
