Distinction Between Well-Standardized Norms and the Psychometric Properties of a Measure

Abstract

Funderburk and Eyberg (1989) described the psychometric properties of the Sutter-Eyberg Student Behavior Inventory (SESBI), a teacher rating scale of disruptive behaviors, for a sample of 55 preschool children. Additional data on the SESBI are presented for a sample of 60 preschool children. While both studies produced almost identical reliability and validity analyses, the scale score means are statistically and clinically different (i.e., a child in the clinical range in one study would be in the middle of the normal range in the other). These findings are used to emphasize the distinction between well-standardized norms and the psychometric properties of a measure. Suggestion are also made as to how behavioral assessment can more thoroughly attend to both of these properties of a measure.
