The development of sex role ideology is an important part of the maturation process. Numerous means have been used to measure sex role ideology. The purpose of this study was to investigate the dimensionality of the construct of sex role ideology. Participants, 180 undergraduate volunteers, completed four multiitem measures of sex role ideology, a social desirability scale, and three single-item questions previously used to assess sex role ideology. Scale internal consistency estimates, correlation coefficients, and a factor analysis were computed. Results of the study suggested that the construct of sex role ideology is unidimensional. © 1988 Plenum Publishing Corporation.
