A note on the reliability and validity of the Minnesota Scale for Paternal Occupations as an estimate of family economic status

Abstract

On the basis of data from approximately a 20% sample of NMS finalists for whom the MSPO and family income data were available indicated that "As a set of classes, the Minnesota Scale for Paternal Occupations appears useful as a crude index of fathers' net income for group purposes. The classification process itself has relatively high interobserver reliability for a sample of two judges." (PsycInfo Database Record (c) 2025 APA, all rights reserved)
