This study sought to demonstrate that neurotic differences could be found among prison inmates chosen according to characteristics of their criminal behavior. 3 groups of 15 white, male, prison inmates were screened from a prison's total population. An individualized group, whose crimes were violent, aggressive, and lacked a financial motive, were found to show significantly different elevations (at the .05 and .01 levels) from the other groups on several subscales of the MMPI and the CPI. These results reflect more neurotic traits in the individualized group than in the more common socialized criminal groups. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
