Premenstrual changes: are they familial?

To investigate the potential familial component in premenstrual changes, 80 pairs of sisters were assessed with the Premenstrual Assessment Form, a retrospective measure, and the Daily Ratings Form, a prospective measure, for physical, behavioral and mood changes during the premenstrual phase of the menstrual cycle. Sisters were not found to be concordant for premenstrual changes on measures derived from either procedure, a finding contradictory to previous reports in the literature as well as to our own prior research.
