Examines J. Kagan's (1964) and L. A. Kohlberg's (1966) theories of sex role identity. Both premise relationships among an individual's sex role identity, perception of sex role stereotypes, and own masculine and feminine sex role attributes, but the theories specify different patterns of correlations among these variables. Kagan's theory views sex role identity as the product of the mutual influence of stereotypes and attributes, whereas Kohlberg's posits sex role attributes as the product of the stereotypes and identity. 104 male and 110 female college students were administered measures of each variable including the Personal Attributes Questionnaire (PAQ), modified versions of PAQ to measure stereotypes of men and women, and a measure of sex role identity developed by the present author. Results indicate an overall relationship between sex role identity and the other 2 variables. Results generally support Kohlberg's theory over Kagan's. Significant correlations were found where Kohlberg's theory would predict a relationship--between sex role stereotypes and sex role attributes. Nonsignificant correlations were found where Kagan's theory would predict a relationship--between sex role stereotypes and sex role identity. Results are compared to findings by J. T. Spence et al (1975), and questions are raised about the psychological constructs underlying measures of sex role attributes.
