The fakability of subtle and obvious measures of aggression by male prisoners.

Fifty-eight adult male felons were given the Minnesota Multiphasic Personality Inventory (MMPI), the Buss - Durkee Hostility Inventory ( BDHI ), and the Draw-a-Person Test (DAP) to test the relative sensitivity of subtlety or obviousness of items to response sets. The inmates were randomly assigned to three response set groups: a fake-aggressive group, a fake-nonaggressive group, and a standard-instruction control group. The MMPIs were scored for five obvious and five subtle aggression or hostility research scales. The BDHI is a totally obvious test, whereas the DAP is a very subtle measure. A paradoxical relationship between response set and subtlety of the scales was hypothesized, such that the obvious scales could be successfully faked , but the subtle scales would show scores in the opposite from the intended direction. It was found that the inmates did correctly manipulate the obvious scales, but the subtle scales did not consistently show the hypothesized trend. Possible reasons for this are discussed, including the nature of the scales used and characteristics of the population.
