Abstract We saw that there are many approaches to estimating reliability, each of which generates a different coefficient. One can examine scores from the same observer on two viewings of the same stimulus (intra-observer), different observers of the same stimulus (inter-observer), different occasions separated by a short time ...

Abstract This chapter is a detailed review of generalizability theory (G theory), an extension of classical reliability theory originally devised by Cronbach. The basic concept is that any measurement contains multiple sources of error, and through the use of G theory these various sources can be calculated in a single study.

Generalizability theory: 1973–1980
British Journal of Mathematical and Statistical Psychology, 1981This paper reviews the developments in generalizability theory from 1973 to 1980. The first section presents a sketch of generalizability theory. The second section reviews theoretical contributions about (1) problems associated with estimating variance components, including sampling variability and negative estimates, (2) fixed facets, (3) criterion ...

Generalizability theory consists of a conceptual framework and a methodology that enable an investigator to disentangle multiple sources of error in a measurement procedure. The roots of generalizability theory can be found in classical test theory and analysis of variance (ANOVA), but generalizability theory is not simply the conjunction of classical ...
