Premenstrual changes: patterns and correlates of daily ratings

Area of Science:

• Psychiatry and Behavioral Science
• Women's Health Research
• Reproductive Endocrinology

Background:

• The premenstrual period is often characterized by various physical and emotional changes.
• Existing research sometimes oversimplifies these changes into a singular 'premenstrual syndrome'.
• Understanding the heterogeneity of premenstrual experiences is crucial for accurate diagnosis and treatment.

Purpose of the Study:

• To analyze patterns of covariance in mood, behavior, and physical condition during the menstrual cycle.
• To identify distinct dimensions of premenstrual change.
• To investigate the relationship between these dimensions and a history of affective disorders.

Main Methods:

• Daily ratings of 20 measures were collected from 64 women over one menstrual cycle.
• Statistical analysis, including discriminant analysis, was used to identify patterns.
• Correlation analysis was performed to examine relationships with lifetime affective disorder diagnoses.

Main Results:

• Five distinct dimensions of premenstrual change were identified.
• These dimensions showed differential relationships with a lifetime diagnosis of affective disorder.
• The findings indicate significant heterogeneity in premenstrual experiences.

Conclusions:

• Research should move beyond a singular concept of premenstrual syndrome.
• Focusing on diversified premenstrual changes offers a more nuanced understanding.
• This approach may improve the identification and management of women's mental health conditions related to the menstrual cycle.
