Characterizing Measurement Error in Scores Across Studies: Some Recommendations for Conducting “Reliability Generalization” Studies

Abstract

T. Vacha-Haase (1998) proposed her “reliability generalization” methodology to characterize (a) typical score reliability for a measure across studies, (b) the variability of score reliabilities, and (c) what measurement protocol features predict the variability in score reliabilities across administrations. The present article provides recommendations on how to conduct these studies.
