Abstract:

Generalizability theory is a statistical theory about the dependability of behavioral measurements. Dependability refers to the accuracy of generalizing from a person's observed score on a measure (e.g., behavioral observation, opinion survey, rating scale) to an estimate of her ideal score that would have been received over a defined universe. Generalizability theory liberalizes classical theory by employing analysis-of-variance methods that allow a researcher to untangle multiple sources of error variance, rather than keeping error variance undifferentiated as in classical theory. Although the theory is now over 30 years old, with roots in psychological and educational research, it is only in the last several years that generalizability theory has sprouted in the health sciences. This roundtable will provide an introduction to generalizability theory, discuss its concepts and usefulness, and highlight its practical application in health measurement scales.
