Previous studies have demonstrated that visual analog scales (VASs) are valid and reliable instruments for measuring the severity of premenstrual symptoms. Most of these studies, though, predate the introduction of DSM-IV diagnostic criteria for premenstrual dysphoric disorder (PMDD). Our objective was to assess the reliability and validity of VASs that were revised to better reflect the DSM-IV definition of PMDD.
