This paper is made of a study of 150 patients of depression treated in the Department of Neuropsychiatry, Soo Do Medical College Hospital during the period from April, 1962 through March, 1966.
Cases covered in this paper of 56 males and 94 females. They were comprised from the following diagnostic categories; involutional depression, manic-depressive reaction, psychotic depression and neurotic depression.
In order to distinguish neurotic depression from psychotic depression, the author applied a clinical scale of items to individual case to get either a bimodal distribution which would be taken as evidence for the two type concept, or a normal distribution which would be taken as evidence that two types do not exist.
The results obtained were as follows:
1. In the pretesting study, the interrater relability on the 20 cases scored by two raters was 0.74 (Spearman β) which is significant at the 0.001 level confidence.
2. This study showed a positively skewed distribution but not a sharp division between two types in the distribution of category scale scores.
3. Eleven items out of 16 used in this study showed excellent and good predictors are course independent, though disorder, depressive mood, somatization, guilt, "quality" different, retardation, previous attack of mania and previous attack of depression, and the good predictors are precipitating factor and late insomnia.
4. The correlation between severity and category scale score is much significant (p<0.001).
5. The correlation between the category scale score and age is much significant (p<0.001), and the author found that clinically severe depression are common before the age of 40.
