The Self-descriptive List, a measure of adult stereotypic sex-role concepts of masculinity, and the Rating Scale for Adults, a measure of sex-role adoption, were developed and standardized. The former has 12 items which were determined by a Q-sort procedure to be neutral on social desirability and either high or low on masculinity. The latter has 20 sex-typed, behavioral statements. Both instruments were administered twice to college students and their spouses. Subjects were Caucasian, second generation U. S. citizens of the middle socioeconomic class who were 18 yr. of age or older. Both instruments reliably differentiated between the sexes; furthermore, scores on scales were positively correlated.
