The interquartile range was used to extract the cut-off point, where a score of <= 22 indicated mild symptoms, 23-36 indicated moderate symptoms, and >= 37 indicated severe symptoms. Although premenstrual symptoms per se are experienced by about 90% of women, only around 20% experience symptoms severe enough to cause substantial impairment of daily life activities.[5],[6] No consensus exists on how symptom severity should be assessed.
