Abstract

A history of sexual trauma places women at a high risk for sexual dysfunction and other health sequelae, yet the influence of ovarian hormones in this population is poorly understood. This dissertation tested the theory that the effects of ovarian hormones are mediated by cognitive approach-avoidance systems to shape sexual well-being, and that this process is moderated by sexual trauma history. This was investigated across three studies examining the menstrual cycle, hormonal contraceptive use, and menopause. Across each chapter, I present complementary evidence demonstrating that hormones interact with the interpretation of ambiguous internal and external cues with respect to sexual approach and avoidance outcomes, and a putative role of physical health factors. This research advances an integrated biopsychosocial model, pointing to the need for trauma-informed clinical care that targets cognitive appraisal and the drivers of sexual avoidance to improve women's sexual well-being across the lifespan.
