To determine whether women seeking treatment for symptomatic premenstrual change have ongoing psychological disturbance, we undertook a cross-sectional, comparative study across four groups of reproductive-age women. Subjects were 35 patients with symptomatic premenstrual change and no psychiatric history, 35 women without symptomatic premenstrual change, 35 patients with affective disorders, and 35 women from the community at large. All women except those in the community sample were tested in the intermenstrual phase (after menses but before the 12th cycle day). Psychological tests administered were Profile of Mood States, State-Trait Anxiety Inventory, Institute for Personality and Ability Testing (IPAT) Anxiety Scale, IPAT Depression Scale, General Health Questionnaire and the Family Inventory of Life Events (FILE). Demographic data and information concerning present and past stresses were also collected. Women with symptomatic premenstrual change were distinguishable from psychiatric patients on assessment of intermenstrual mood state. They were no different from women within the community at large or from non-symptomatic women. When symptomatic women reported on time periods, which include the premenstrual phase of the cycle, we found results at variance with those obtained in relation to current state mood. While not unlike the women from the community at large in longer term affective characteristics, they were consistently different from non-symptomatic women and sometimes indistinguishable from psychiatric patients. Women with symptomatic premenstrual change also reported higher levels of past external stresses than women taken from the community at large.
