BACKGROUND: The presence of psychotic symptoms in bipolar disorder (BD) is considered a feature of higher severity of illness and, in particular, of manic episodes in bipolar I disorder (BD I). However, the possibility to apply the "with psychotic features" specifier to major depressive episodes in either bipolar II disorder (BD II) or BD I highlights the need for additional research in this area. METHODS: The present study assessed the lifetime presence of psychotic symptoms and related socio-demographic and clinical features in a large sample of BD patients (N=360), with (BDPs, N=207) and without a lifetime history of psychosis (BDNPs, N=153). RESULTS: An overall less favorable socio-demographic profile was observed in BDPs vs BDNPs. In terms of clinical variables, BDPs vs BDNPs had: earlier age at onset (27.7±10.5 vs 30.1±12.3years; p=0.02), higher rates of BD I diagnosis (95.7% vs 45.8%; p<0.001), more elevated (manic/hypomanic/mixed) polarity of first (55.2% vs 24.4%; p<0.001) and most recent episode (69.8% vs 35.6%; p<0.001), more comorbid alcohol/substance use disorder (38.1% vs 21.9%; p=0.002), more lifetime hospitalizations (3.8±6.1 vs 2±3; p=0.002) and involuntary commitments (1±1.9 vs 0.1±0.4; p<0.001), more history of psychosocial rehabilitation (17.9% vs 5.7%; p=0.001), more current antipsychotic use (90.1% vs 70.9%; p<0.001), and lower GAF (62.3±14.2 vs 69.3±12.5; p<0.001), but shorter duration of most recent episode (34.1±45.4 vs 50.3±65.7days; p=0.04), lower rates of comorbid anxiety disorders (23.9% vs 38.2%; p=0.005), and antidepressant use (19.4% vs 56.6%; p<0.001). CONCLUSIONS: The present findings indicate an overall worse profile of socio-demographic and certain clinical characteristics associated with the lifetime presence of psychotic symptoms in bipolar patients.
