Isi artikel

The present article addresses reliability issues in light of recent studies and debates focused on psychometrics versus datametrics terminology and reliability generalization (RG) introduced by vacha - haase. The purpose here was not to moderate arguments presented in these debates but to discuss multiple perspectives on score reliability and how they may affect research practice, editorial policies, and RG across studies. Issues of classical error variance and reliability are discussed across models of classical test theory, generalizability theory, and item response theory. Potential problems with RG across studies are discussed in relation to different types of reliability, diffrerent forms, different number of items, misspecifications, and confounding independent variables in a single RG analysis.
