Women With Generalized Anxiety Disorder Show Increased Repetitive Negative Thinking During the Luteal Phase of the Menstrual Cycle

Abstract

Repetitive negative thinking (RNT) is a transdiagnostic feature of psychiatric disorders. Women report greater RNT than do men, yet the association between uniquely female characteristics, such as fluctuating sex hormones during the menstrual cycle, and RNT has not been established. Here we examined changes in RNT and anxiety symptoms across the menstrual cycle in women with (n = 40) and without (n = 41) generalized anxiety disorder (GAD). Women with GAD reported an increase in RNT and negative affect from the follicular phase to the luteal phase; unexpectedly, this was not associated with changes in anxiety symptoms, estradiol, or progesterone. Nonanxious women reported no changes in RNT or anxiety symptoms over the menstrual cycle, but higher within-participants progesterone was associated with reduced RNT and negative affect. These results indicate that uniquely female biological processes may influence core cognitive processes that underlie anxiety disorders, but further investigations to determine the implications for symptom severity are required.
