In order to examine the relationship of attitudes about menstruation to self-reports of menstrual-related symptomatology as well as to other aspects of behavior, an instrument to measure attitudes concerning menstruation was developed. After constructing the Menstrual Attitude Questionnaire (MAQ), the factor analytic structure of the original MAQ sample was replicated on a second sample. Summary statistics are presented for college women, college men, and adolescent girls, and the relationship between menstrual-related attitudes, expectations, and experience is examined.
