Abstract
The Sex-Role Egalitarianism (SRE) Scale, recently developed to measure attitudes toward the equality of males and females, consists of two 95-item forms assessing attitudes across five domains of adult life. In this study, a three-facet (items, forms, and testing occasions) random effects generalizability analysis was used to evaluate the precision of each of the domain measures. Ninety-seven male and female psychology students, business students, and senior citizens completed both SRE forms on two separate occasions. Estimates of variance components, generalizability coefficients, and error were computed and examined for indications of measurement precision when generalizing over items, forms, and occasions. Two additional data collection designs are proposed and discussed, with estimates of precision and error presented for varying numbers of levels of the facets of interest.
