Premenstrual affective syndrome and affective disorder.

Sixty-four per cent of 874 freshmen and sophomore women sent questionnaires about premenstrual and menstrual symptoms returned them. They differed from those not returning the questionnaires only in year of school. As predicted, women reporting premenstrual affective symptoms were more likely than those who did not report them to seek psychiatric care at the Student Health Service and to be diagnosed as affective disorder at the service.
