| Abstract: | We empirically evaluated indexes derived from the Rorschach Comprehensive System (CS) and the Rorschach Performance Assessment System (R–PAS) that are used for the assessment of psychotic functioning in schizophrenia. We compared the Perceptual Thinking Index (PTI) and the Ego Impairment Index (EII–2) with their revised versions: Thought and Perception Composite (TP–Comp) and EII–3. We evaluated their predictive validity for differentiating schizophrenic from nonschizophrenic patients in a Serbian sample. The sample consisted of 211 (109 men and 102 women, 18–50 years old) inpatients in Serbia who were divided into 2 groups: schizophrenic (100) and nonschizophrenic (111). Test administration, coding, and form quality classification followed CS guidelines. Logistic regression analysis indicated that the new indexes TP–Comp and EII–3 have slightly better predictive power than their counterparts, PTI and EII–2, in identification of schizophrenia, and that TP–Comp performed better than other indexes, although all 4 indexes were successful in differentiating these groups. The results supported the use of TP–Comp in diagnosis of schizophrenia and generally provided evidence for the utility of the Rorschach in evaluating psychosis and for its use in a cross-national context. |
