Premenstrual symptoms screening tool (PSST)
PMS
PMS
This 19‐question tool with two domains retrospectively examines the severity of PMS symptoms. The first domain includes 14 items related to psychological, physical, and behavioral symptoms, and the second domain (five items) measures the effect of these symptoms on the individual's life. Each question is rated on a 4‐point scale, i.e., not at all, mild, moderate, and severe, ranging from 0 to 3. To determine the mild to severe PMS, the researchers must simultaneously meet the following three conditions: there should be at least one item with moderate to severe from items 1 to 4, at least four items with moderate to severe from items 1 to 14, and one item in the second domain must be mild or severe. In addition, this instrument is used to screen the PMDD. It requires the following three conditions to be simultaneously detected: at least one severe item from items 1 to 4, at least four moderate or severe items from items 1 to 14, and at least one severe item in the last five items.
