Considering DSM-5: personality diagnostics in patients with schizophrenia spectrum disorders.

The aims of this study were to examine the prevalence of personality disorders (PD) in patients with schizophrenia spectrum disorders (SSD), to examine the interaction of axis-I and axis-II symptoms to provide an estimate on the confounding potential of SSD psychopathology in the establishment of DSM-IV PD diagnoses, and to discuss implications concerning the proposed changes in DSM-5. Patients with SSD, aged 18 to 65 years, and being at least partially remitted (PANSS total score < 75) were included. PD was examined categorically and dimensionally using the SCID-II screening questionnaire and interview, and SSD psychopathology was rated using the Positive and Negative Syndrome Scale for Schizophrenia (PANSS).
