Late luteal phase dysphoric disorder in young women. The authors determined the prevalence of late luteal phase dysphoric disorder in 217 university women aged 17-29 years. Unaware of the focus on premenstrual syndrome (PMS), the participants rated DSM-III-R symptoms of late luteal phase dysphoric disorder over 90 days. Using a 30% or greater premenstrual change as an index of luteal variation, the authors found that 10 women (4.6%) met the symptom criteria during two menstrual cycles. Compared to 25 young women seeking treatment for PMS who met the same diagnostic criteria, the 10 women from the university sample reported significantly less fatigue and impaired concentration and somewhat less severe depression and overall symptoms.
