title: A comparison of new and revised Rorschach measures of schizophrenic functioning in a Serbian clinical sample.
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.
