Rumination and mindfulness are known risk and protective factors for mental health, but their role in Premenstrual Dysphoric Disorder (PMDD) is unclear. In 60 women with PMDD and 60 healthy controls, brief ambulatory inductions of ruminative and mindful self-focus were administered during the follicular and late luteal phases. Women with PMDD showed stronger increases in positive affect in response to mindful self-focus during the late luteal phase, but not during the follicular phase. Across all participants, induced rumination immediately increased negative affect and rumination while decreasing present-moment awareness, whereas mindful self-focus increased self-acceptance. These results suggest that cycle-phase-specific mindfulness interventions may benefit PMDD, and that both rumination and mindfulness are targets for brief interventions regardless of cycle phase or clinical status.
