The hypothesis that suicidal individuals think more dichotomously than other emotionally disturbed people and normal subjects was tested by the use of the Semantic Differential test. The results indicate that the suicidal and the psychosomatic subjects scored higher than the normal subjects. It was concluded that Dichotomous Evaluative Thinking seems to be a common characteristic of emotionally disturbed persons and was not an exclusive factor in the thinking of suicidal individuals. (CI)
