The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Validity scales (L, F, and K) were used to identify subgroups of inpatients seeking treatment for alcoholism and to determine the extent that assessed test-taking attitude could be generalized to other alcohol assessment instruments. Cluster analysis of the inpatients receiving treatment for alcoholism identified 3 distinct response style subgroups: defensive, straightforward, and exaggerated. These patterns were confirmed in a 2nd sample. Calibration equations were generated and used to classify a subsequent sample into subgroups, and expected differences were found across the subgroups on the Alcohol Use Inventory (J. L. Horn, K. W. Wanberg, & F. M. Foster, 1987) and the Inventory of Drinking Situations (H. M. Annis, 1982). These preliminary results suggest that MMPI-2 response style is associated with response to other alcohol abuse assessment instruments. Future research examining the relationship between test-taking attitude and treatment involvement and outcome is discussed. Meehl and Hathaway (1946) were among the first researchers to suggest that personality inventories were susceptible to both conscious "faking" and unconscious self-deception. In their landmark Minnesota Multiphasic Personality Inventory (MMPI; Meehl & Hathaway, 1946) work, they devised the Lie (L) and Correction (K) scales (Meiydith & Wallbrown, 1991) to assess response bias. The L scale assesses overall frankness in the individual's approach to the instrument. High L scores are indicative of an unsophisticated attempt to present oneself in a favorable light. The K scale assesses a more subtle attempt to respond defensively and is indicative of an attempt to deny problems and demonstrate no need for psychologi-
