Styles of Regulation in the Bipolar Spectrum

Abstract

Styles of regulation were assessed with the Serial Color-Word Test in a group of 35 compensated DSM-III—R bipolar patients (Bipolar) and in 3 control groups: Major Depression ( n = 35), Schizophrenia ( n = 50), and self-rated Personality Disorder ( n = 40). On several measures of nonlinear change (V), patients in the Bipolar group had mean scores between those of the Personality Disorder and the Schizophrenic groups, and overlapped with those of the Major Depression group. Patients in the Bipolar group with clearcut temperaments (hyperthymic or depressive) were significantly more dissociative and less stabilized than other patients in the same group. A further group of nonclinical subjects with hyperthymic temperament ( n = 20) was significantly more dissociative than the Personality Disorder group.
