In the PMS group 30% (n = 17) had no depression; 38% (n = 21) had mild depression; 23% (n = 13) had moderate depression; and 7% (n = 4) had severe depression. In the group with no PMS 60% (n = 27) had no depression; 20% (n = 9) had mild depression; 17% (n = 8) had moderate depression; 2% (n = 1) had severe depression. The rate of depression was significantly higher in PMS group (p = 0.04).
