This paper compares two classifiers: Pseudo Bayesian and Neural Networ
k for assisting in making diagnoses of psychiatric patients based on a
simple yes/no questionnaire which is provided at the outpatient's fir
st visit to the hospital. The classifiers categorize patients into thr
ee most commonly seen ICD classes, i.e. schizophrenic, emotional and n
eurotic disorders. One hundred completed questionnaires were utilized
for constructing and evaluating the classifiers. Average correct decis
ion rates were 73.3% for the Pseudo Bayesian Classifier and 77.3% for
the Neural Network classifier. These rates were higher than the rate w
hich an experienced psychiatrist achieved based on the same restricted
data as the classifiers utilized. These classifiers may be effectivel
y utilized for assisting psychiatrists in making their final diagnoses
.
