Exploring aspects of DSM-IV interpersonal sensitivity in bipolar II.
BACKGROUND
The aim of the study was to find the prevalence of interpersonal rejection sensitivity (IRS) (a personality trait in DSM-IV) in bipolar II and unipolar depression.


METHODS
557 consecutive unipolar and bipolar II outpatients, presenting for depression treatment, were interviewed with the DSM-IV Structured Clinical Interview and the Global Assessment of Functioning Scale. DSM-IV atypical features criteria (which include IRS) were followed.


RESULTS
IRS was significantly more common in bipolar II than in unipolar patients (37.8% vs. 20.5%, odds ratio 2.3, P=0.0000). Sensitivity and specificity for bipolar II diagnosis were 37.8% and 79.4%.


CONCLUSIONS
IRS personality trait seems to be more common in bipolar II than in unipolar depression.


CONCLUSIONS
reliability of bipolar II diagnosis, non-blind, cross-sectional assessment, single interviewer.
