The Premenstrual Assessment Form (PAF) provides frequencies of diagnoses for subjects meeting the criteria for typological classifications which are similar in New York and Edmonton, suggesting that the instrument is stable in assessing premenstrual complaint. However, the frequency with which an unselected population meet the criteria suggests that more strict criteria and/or a “severity index” would be appropriate. It seems likely that a modified form of the PAF could fulfil some of the intentions of its originators.
