• Rorschach

The Rorschach-based Perceptual Thinking Index (PTI) is used to identify and rate features of psychotic disorders, but effects of antipsychotic treatment on such ratings is not clear. Accordingly, we examined potential effects of antipsychotic drugs on PTI measures in 114 patients with a psychotic or bipolar-I disorder. Use and doses of antipsychotic drugs (as chlorpromazine-equivalent [CPZ-eq] mg/day) were unrelated to PTI total or subscale scores in any diagnostic group. PTI scores were independently and significantly associated with psychotic symptomatic severity (PANSS score) and less with female sex. These findings support the validity and value of the PTI in identifying features of psychosis even in the presence of antipsychotic treatment.
