Diagnostic accuracy and factor structure of the AAS and APS scales of the MMPI-2.
Receiver operating characteristics analysis and sensitivity analysis were used to compare the diagnostic accuracy of the Addiction Acknowledgement Scale (AAS; Weed, Butcher, McKenna, & Ben-Porath, 1992) and Addiction Potential Scale (APS; Weed et al., 1992) of the Minnesota Multiphasic Personality Inventory-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) to that of the MacAndrew Alcoholism Scale-Revised (Butcher et al, 1989), the CAGE (Mayfield, McLeod, & Hall, 1974), and Svanum's scale (Svanum & McGrew, 1995) in a sample of 338 university students. The AAS was the most accurate of these 5 scales at identifying current alcohol dependence (as measured by a structured diagnostic interview) and appears to offer considerable promise as an alcohol screening instrument. In contrast, the APS performed the most poorly of the 5 scales being evaluated, yielding results that would be of minimal clinical utility. Factor analysis yielded a 2-factor solution for the AAS (Acknowledgement of Alcohol/Drug Problems; Positive Alcohol Expectancies) and a 4-factor solution for the APS (Satisfaction with Self; Cynicism/Pessimism; Impulsivity; Risk-Taking).
