Note. BPD = borderline personality disorder; TM = trait-matched group; NTM = non-trait-matched group; NEO-PI-R = Revised NEO Personality Inventory; SSPRS = Subjective Stress Perception Rating Scale; DSS = Dissociation Tension Scale. Degrees of freedom with decimal places denote Brown-Forsythe Robust Test of Equality of Means (correcting for inhomogeneity of variance). Row means with different subscripts are significantly different from each other at p < .05 or less using Bonferroni-corrected (or Tamhane’s T2 in the case of inhomogeneity of variance) post-hoc tests. Degrees of freedom differ for NEO-PI-R scales because of missing data.
