Used a cross-validational approach to compare MMPI scale elevations and profile patterns produced by 22 female murderers and 40 female nonviolent offenders in 2 geographic regions. Ss did not differ between groups in race distribution, age, education, age at or months served on current offense, total time incarcerated, or intellectual level. Ss also completed the Shipley-Institute of Living Scale for Measuring Intellectual Impairment and the Raven Progressive Matrices. Murderers from both prison sources produced subdued group mean profiles, whereas nonviolent offenders were characterized by elevations on Scale 4. Discriminant function classification was highly dependent on scores on Scales 4, 5, K, and A and correctly identified 82% of violent and 78% of nonviolent offenders. A principal-components analysis yielded 5 components of profile types, but only the component defined by high positive loadings for Scale 4 differentiated between the groups.
