BPD = borderline personality disorder; DSS-4 = Dissociation Tension Scale 4; (25) PTSD = posttraumatic stress disorder; SD = standard deviation.
↵* Determined by use of 2-tailed t tests for dependent variables.
↵† Vividness, tension and pain were rated on Likert scales ranging from 0 (low) to 9 (high)
