In a random sample of 500 British women Coppen and Kessel (1963) found that certain menstrual symptoms—those of the premenstrual syndrome—i.e. depression, irritability, swelling, as well as menstrual irregularity, were positively correlated with Neuroticism on the Maudsley Personality Inventory. In a further study on the prevalence of menstrual symptoms in psychiatric patients (Coppen, 1965), a high incidence of menstrual symptoms was found in all groups, particularly neurotic women. Both these surveys were conducted by means of a menstrual questionnaire completed by each woman. This approach allows different groups to be investigated and compared, using a standardized measuring instrument. The purpose of this investigation was to see if cultural factors have any influence on the prevalence or severity of menstrual symptoms by administering a translation of the menstrual questionnaire to a sample of Spanish college students.
