Background. Artificial Neural Network (ANN), as a potential powerful classifier, was explored to assist psychiatric diagnosis of the Composite International Diagnostic Interview (CIDI). Method. Both Back-Propagation (BP) and Kohonen networks were developed to fit psychiatric diagnosis and programmed (using 60 cases) to classify neurosis, schizophrenia and normal people. The programmed networks were cross-tested using another 222 cases. All subjects were randomly selected from two mental hospitals in Beijing. Results. Compared to lCD-10 diagnosis by psychiatrists, the overall kappa of BP network was 0.94 and that of Kohonen was 0.88 (both P< 0.01). In classifying patients who were difficult to diagnose, the kappa of BP was 0.69 (P<0.01). ANN-assisted ClDl was compared with expert system assisted CIDI (kappa=0.72-0.76); ANN was more powerful than a traditional expert system. Conclusion. ANN might be used to improve psychiatric diagnosis. [ABSTRACT FROM AUTHOR]
