Psychometric properties of an instrument 3: convergent, discriminant, known-groups, and criterion validity

Eun‐Hyun Lee

Open full text 14 citations

Abstract

Before evaluating convergent, discriminant, and known-groups validity, it is suggested to design an instrument that reflects hypothetical relationships or differences with other comparator instruments or groups. For criterion validity, a gold-standard instrument measuring the same construct should be carefully selected.
