Aggressive response sets and subtle-obvious MMPI scale distinctions in male offenders

The effects of aggressive and nonaggressive response sets on the MMPI subtle and obvious clinical subscales were investigated. Fifty-eight male prison inmates answered the MMPI as if they were either highly aggressive or highly nonaggressive. The clinical scales with sufficient items in each category were scored for subtle, neutral, and obvious subscales. Inmates successfully feigned aggressiveness on several of the obvious subscales (p = .0056) and one neutral scale; the subtle subscales were not significantly different across groups, consistent with previous research on this population in terms of the resistance of subtle items to these response sets.
