One hundred (39 women and 61 men) hospitalized substance abusers were
administered the MMPI and MMPI-2. The correspondence of T-Scores, Code
types, and MAC/MAC-R scores were analyzed. Results showed that the MMP
I-2 produced profiles that were consistent with previous research on t
he MMPI with substance abusers. However, the relationship between MMPI
and MMPI-2 T-scores appeared complex and varied across individual sca
les for both men and women. Codetype congruence was 38% for one, two,
and three-point codetypes. Well-defined codetypes accounted for 30% of
the profiles. MAC/MAC-R raw scores were different for men but not for
women. Codetypes established for the MMPI may not be fully transferab
le to the MMPI-2 in a substance abusing population. (C) 1996 John Wile
