[Analysis of personality traits on felons]

To study the personality traits of felons and their relevant factors, and to recommend for criminal psychological correction and crime prevention.

Using Minnesota Multiphasic Personality Inventory (MMPI) to test felons in initial and middle stage of sentence serving.

The differences of MMPI factors between felon group and normal group were statistically significant (P < 0.001). The felon group's raw scores in F, Pd, Pa, Pt and Sc factors were significantly higher than those of the normal group. The felons whose T score of Pd was higher than that of the normal group by one standard deviation had the largest proportion. In subscales of F, Hs, D, Hy, Pd, Pa, Pt, Sc and Ma, the proportion of people whose T score higher than the normal was relatively large. The supernormal proportion in the two-point code type was large.

Felon group is a special group with high-risk personality disorder. It is important to take more correctional research on them.
