The MMPI-2 was administered to 56 adult male offenders in a maximum-security prison serving a life sentence for first degree murder. This study evaluated the predictive ability of the MMPI-2 scales 4, 6 and 9 to distinguish among groups of inmates with high and low infraction rates. Results indicated that as the weighted infraction rate (WRI) increased above 9, the T score on scale 4 sharply decreased at the same rate of the increase for 0-9 WRI. Results also supported a relationship where as the T score on scale 9 increased the WIR also increased. Inmates who refused to comply with psychological testing have a lower WIR as compared to the other two sample groups. MMPI-2 scales 4 and 9 have predictive abilities with offenders in regards to the level of infractions.
