In this study the authors tested the acquired preparedness model of problem drinking, which holds that trait disinhibition, defined as neurotic extraversion by C. M. Patterson and J. P. Newman (1993), leads to the biased formation of positive over negative alcohol expectancies. Positive expectancies thus mediate disinhibition's influence on drinking. The authors also hypothesized that disinhibition moderates the expectancy-drinking relationship such that disinhibited individuals are more likely to act on their positive expectancies. In Study 1, positive expectancies both mediated and moderated the disinhibition-drinking relationship. In Study 2, learning task results indicated that disinhibited individuals sought reward, even when passive avoidance of punishment was indicated. Study 2 also replicated Study I hypotheses for men but generally not for women.

The factor-based meaning of these measures appears to be consistent across race. The measures correlate similarly across race, suggesting that the risk process may be similar for both races, but African American women endorsed significantly fewer risk factors and fewer symptoms.
