We examined 60 substance abusers (SA) on the Millon Clinical Multiaxial Inventory-III (MCMI-III; Millon, 1994) and on eight Rorschach variables from the Comprehensive System (CS; Exner, 2003). On the MCMI-III, SA scored above the cutoff for clinical significance (M ≥ BR 70) on Drug Dependence (94.77), Antisocial (82.95), Depressive (74.33), Self-Defeating (71.48), and Alcohol Dependence (70.70). On seven of the CS variables (M+,o,u, XA%, X-%, WSum6Lv2%, M-%, SumT%, and Pure H%) the scores of the SAs suggested significant more psychopathology compared to the scores of 60 university students, whereas the SA's scores on six of these variables (M+,o,u, XA%, X-%, WSum6Lv2%, SumT%, and Pure H%) suggested significantly less psychopathology compared to the scores of 36 schizophrenics. The effect sizes for the significant differences were in the small, medium and large range (d= 0.31 to d= 1.87).
