  • * Test of gender*calendar period*depression (at first interview) interaction in the 1952 sample: χ2 = 2.75, df = 2, p = 0.3; 1970 sample: χ2 = 1.91, df = 1, p = 0.2; and 1992 sample: χ2 = 0.03, df = 1, p = 0.9.

  • Test of gender*calendar period*depression (at recent interview) in the 1952 sample: χ2 = 3.16, df = 2, p = 0.2); 1970 sample: χ2 = 3.68, df = 1, p = 0.05); and 1992 sample: χ2 = 0.03, df = 1, p = 0.9.
