Objective: While premenstrual dysphoric disorder (PMDD) as defined in DSM has become an established diagnosis, and a formal indication for drug treatment, the relative impact of the disparate symptoms named in the criteria, and to what extent they indeed constitute parts of one syndrome, remains insufficiently clarified. We have therefore explored the frequency, impact, and inter-relationship of different PMDD symptoms. Method: Using a web survey, 10,457 Swedish women of fertile age were asked to retrospectively assess if they experience reduced functioning due to symptoms clearly associated with the premenstrual phase. Those responding affirmatively reported presence, severity, and impact of each symptom named in the PMDD criteria. Result: Nine percent reported impairing premenstrual symptoms. Whereas irritability was reported to cause impairment in 77% of those passing the gate questions, somatic symptoms were common but seldom causing impairment. A vast majority reported presence of at least 5 different symptoms, as required to meet the PMDD criteria, but few reported each of 5 different symptoms to be severe or impairing. An analysis of the association between symptoms revealed clear-cut clustering of somatic and mood symptoms, respectively. Conclusion: While retrospective account suggested irritability to be the clinically most important premenstrual symptom, some of the complaints named in the PMDD criteria were not or only weakly associated with mood symptoms and also reported to be of limited clinical significance. It is concluded that regarding all symptoms listed in the DSM criteria as clinically relevant manifestations of one and the same syndrome may be questioned.
