Diagnostik prämenstrueller Störungen

BACKGROUND AND OBJECTIVE: There is no valid method in the German literature for assessing premenstrual disorders. This study was undertaken to translate into German, validate and test the reliability of the "Premenstrual Syndrome Tension Observer/Self-Rating Scale" and the "Visual Analogue Scale for Premenstrual Disorders". PATIENTS AND METHODS: 55 patients diagnosed with premenstrual dysphoric disorder took part in the study. After fullfilling the inclusion criteria, sociodemographic and medical data were studied. The self-assessment by PMTS-SR and VAS-PmD was done two days premenstrual and nine days postmenstrual by all 55 patients. The objective assessment (done by a clinical interview and the PMTS-O as the reference standard) was obtained afterwards without knowing the self-assessment. RESULTS: The average age of the tested women was 35 years. The average increase of 85 % in premenstrual symptoms (PMTS-O and PMTS-SR scale) indicates a group with severe premenstrual disorders. The correlation coefficient between PMTS-O and PMTS-SR scale, pre- and postmenstrually, was 0.83 and 0.84, respectively (p < 0.0001 for both). The correlation coefficient between PMTS-O and VAS-PmD, pre- and postmenstrually, was 0.5 and 0.69, respectively (p < 0.0001 for both). This was calculated at 0.64 and 0.67, respectively (p < 0.0001 for both) between PMTS-SR and VAS-PmD. Reliability analysis for PMTS-O was, pre- and postmenstrually, 0.71 and 0.29, respectively, for PMTS-SR 0.77 and 0.78, respectively, and for VAS-PmD it was 0.79 and 0.87, respectively. CONCLUSIONS: The German version of the PMTS-O and the PMTS-SR scale are "application friendly" as well as proven to be a valid and reliable method for supporting the diagnosis, course of disease and research aspects concerning premenstrual disorders. Initially VAS-PmD should be used in combination with PMTS-O and PMTS-SR scale.
