Fifty-eight subjects self-referred for premenstrual difficulty were
evaluated for late luteal phase dysphoric disorder through a spectral
analysis technique applied to prospective symptom ratings. Data from the
Schedule for Affective Disorders and Schizophrenia--Life-time Version were
used to group the subjects according to the absence or presence of past or
present psychiatric disorders. The two psychiatric groups were compared
with regard to both patterns of significant symptom change and premenstrual
symptom severity. Differences between the groups are used to discuss issues
regarding the reliable identification of late luteal phase dysphoric
disorder and the impact of other psychiatric disorders on this syndrome.
