Statistics: MDE with irritability was present in 59.7% (208/348) of BP-II and in 37.4% (95/254) of MDD (p=0.0000). In BP-II, MDE with, versus MDE without, irritability had significantly younger index age, higher rates of axis I comorbidity, atypical depressive features, and DMX. Upon logistic regression, we found a significant independent association between BP-II MDE with irritability and DMX. In UP, MDE with, versus without, irritability had significantly younger age and age at onset, higher rates of atypical depression, DMX, and bipolar family history. Logistic regression revealed a significant independent association between MDE with irritability and DMX. Given that we had excluded patients with borderline personality, the high prevalence of irritable-hostile depressives in this outpatient population means that hostility cannot be considered the signature of that personality.
