Detecting Differential Rater Functioning over Time (DRIFT) Using a Rasch Multi-faceted Rating Scale Model.
Peer reviewed Peer reviewed
Wolfe, Edward W.; Moulder, Bradley C.; Myford, Carol M. – Journal of Applied Measurement, 2001
Describes a class of rater effects, differential rater functioning over time (DRIFT), that depicts rater-by-time interactions. Also describes Rasch measurement procedures designed to identify these types of DRIFT in rating data. Applied these procedures to simulated data to show their usefulness in classifying raters as aberrant or non-aberrant…
