CRIME AND PERSONALITY REVISITED

The present study explored the effects of MMPI response sets on relatonships between crime and personality in self-report studies. The MMPI-168 and a 21-item delinquent behavior questionnaire were administered to 1680 high school students. The Psychopathic Deviate, Schizophrenia, and Hypomania scales of the MMPI-168 were correlated with delinquent behaviors, with and without control for the L, F, and K scales of the MMPI-168, considered separately and simultaneously. Controlling for F eliminated some relationships and significantly diminished the magnitude of others, while control for L and K had no significant effect. Studies of this nature that fail to control for the F type of response set may produee largely illusory results.
