The Internal and External Optimality of Decisions Based on Tests.

Mellenbergh, Gideon J.; van der Linden, Wim J.

Applied Psychological Measurement, v3 n2 p257-73 Spr 1979

For six tests, coefficient delta as an index for internal optimality is computed. Internal optimality is defined as the magnitude of risk of the decision procedure with respect to the true score. Results are compared with an alternative index (coefficient kappa) for assessing the consistency of decisions. (Author/JKS)
