Ego control and criminal behavior.

Abstract

The personality assessment literature using deviant and antisocial subject populations contains an interesting anomaly—that persons representing major criminal offense categories can be only weakly distinguished from one another by using standard scales of the best conventional inventories (e.g., the Minnesota Multiphasic Personality Inventory and the California Psychological Inventory). This may reflect the fact that existing inventories are designed principally to predict maladjustment or social competence, and most criminal groups tested are found to be equally maladjusted and socially immature. The construct of ego control is not strongly related to adjustment or competence, but rather appears to underlie preference for different life-styles and occupations. This article demonstrates the ability of ego control to distinguish between the offense categories of murder and drug related crimes. A sample of 59 murderers was found to score significantly higher than a group of 56 drug offenders on a rudimentary measure of ego control.
