Abstract

OBJECTIVES: This study was designed to explore the characteristics of schizophrenic patient's PAI profiles and extract the representative profile types and test the diagnostic function of PAR and SCZ for the schizophrenia.
METHODS
252 schizophrenic patients and 168 normal adults completed PAI. The mean profiles of scizophrenia subtypes were compared and the typical profile type were extracted by Ward's hierarchical cluster analysis. The diagnostic function of PAR and SCZ were also tested by discriminant analysis.
RESULTS
The scale and subscale's elevation were different in cach subtype of schizophrenic patients and 5 cluster profiles were extracted. The classification percentage of PAR and SCZ to discriminate normal adult and schizophrenic patients in the discriminant function sample were 83.3%, 79.8%, respectively. It was 86.9%, 72.6% in the holdout sample, respectively, and the overall percentage of cases correctly classified in two samples was 80.7%.
CONCLUSION
These results suggest that PAI scales reflect the chief complaints and related features of schizophrenic patients and the diagnostic function of PAR and SCZ scales are high, Further, these results indicate that PAI can be useful in many clinical field.
