The admission Arrow-Dot scores of 52 mental patients who were placed in a maximum security cottage of a state hospital because of their inability to control their impulses were compared with a control group of 52 patients whose behavior did not create a management problem for the institution. Statistical analysis showed that the Impulse and Ego scores of the two groups differed; the patients presenting a management problem had higher I scores and lower E scores. Females in the maximum security cottage had higher I scores and lower E scores than did the males.
