An MMPI measure of aggression formed by summing scales F (Frequency), 4 (Psychopathic Deviate), and 9 (Hypomania) discriminated 3 groups of neuropsychiatric outpatients (N = 138) defined by qualitative and quantitative differences in violent behavior. Results indicate that the group differences cannot be attributed to differences in more general factors such as age, sex, education, IQ, or degree of overall psychopathology, reflecting favorably on the measure's discriminant validity. However, there was sufficient overlap among the distributions of groups to call its clinical utility into question. Further research appears to be needed in order to better define what this scale measures as well as its range of applicability. (5 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
