Affective Risk Associated With Menstrual Cycle Symptom Change.

For sample 1, the overall model was marginally significant ( F (2, 210) = 2.59; p = 0.08), with a negative but non-significant linear effect ( t = −1.46; ns ), and a significant accelerating quadratic effect, ( t = 2.28; p < 0.05); and for sample 2, the overall model was significant ( F (2, 160) = 5.34; p = 0.006), with a negative but non-significant linear effect ( t = −1.32; ns ), and a significant accelerating quadratic effect, ( t = 3.03; p = 0.003).
