“…The prevalence of clinically significant premenstrual symptoms that are characterized by impairment, treatment seeking, and suicide risk, but do not meet DSM-IV requirement for the presence of five different symptoms, raises the percentage of afflicted women to 13–19% (Angst, Sellaro, Merikangas, & Endicott, 2001; Bunevicius, Leserman, & Girdler, 2012; Spitzer, Williams, Kroenke, Hornyak, & McMurray, 2000). PMDD is characterized by the cyclic recurrence of affective and somatic symptoms in the luteal phase of the menstrual cycle, resulting in luteal phase impairment equivalent to that of major depression, panic disorder, and post-traumatic stress disorder (PTSD) (Kroll & Rapkin, 2006; Lystyk & Gerrish, 2006). The most frequent core symptoms of PMDD are irritability, anger conflict, and emotional lability, and as mindfulness has demonstrated effectiveness in addressing similar symptoms in previous research (Greeson, 2009), we rationalized that mindfulness may be efficacious in treating women who suffer from impairment and distress due to symptoms of PMDD.…”
