Personality traits in LLPDD and normal controls during follicular and luteal menstrual-cycle phases.

In 15 women with Late Luteal Phase Dysphoric Disorder (LLPDD) and in 15 normal control subjects, personality traits were assessed using the Millon Clinical Multiaxial Inventory (MCMI) during follicular and luteal menstrual-cycle phases. Compared with controls, LLPDD subjects had less compulsive but more passive/aggressive and borderline/cycloid traits, and more depression and hypomania. Menstrual-cycle phase did not significantly affect personality variables in either group. In particular, depression and hypomania in LLPDD subjects suggests a relationship with affective disorders.
