title: Screening of patients for clinical trials of premenstrual syndrome/premenstrual dysphoric disorder: methodological issues.
abstract: For many clinical trials patients are first screened by telephone for inclusion and exclusion criteria. Initial screening procedures for women with premenstrual syndrome or premenstrual dysphoric disorder substantially affect the yield of subjects. It is also questionable whether the eventually selected women actually represent the general population of women with these disorders.
