This study was intended to investigate the alcohol outcome expectancy which is the underlying cognitive factor of drinking and analyze the relationship between alcohol expectancy and drinking behavior. Also, this study tested the efficiency of alcohol expectancy challenge intervention on alcohol dependent inpatients. In this study, the explicit and implicit alcohol outcome expectancies in the following groups, including nondrinkers, social drinkers, and alcohol dependent patients, were compared. The explicit positive alcohol expectancies of the social drinker group and the alcohol dependent group were higher than that of the nondrinker group. The explicit negative alcohol expectancy of the social drinker group was lower than that of the nondrinker group and the alcohol dependent group. The implicit positive alcohol expectancies of the social drinker group and the alcohol dependent group were higher than that of the nondrinker group. The implicit arousal alcohol expectancy of the alcohol dependent group was higher than that of the social drinker group and the nondrinker group. These results indicate that each alcohol use group expects different effects of alcohol and the motivation that determines drinking behavior is different. Furthermore, the strong implicit arousal alcohol expectancy of alcohol dependent group matches the incentive-sensitization theory. Correlation between the alcohol expectancy and drinking behavior were analyzed and the stepwise multiple regression analysis was conducted in the next section. The analysis showed that the explicit positive alcohol expectancy had strong correlations with FREQ(frequency of drinking), TQTY(total quantity of drinks), and MAX(maximum number of drinks consumed on any one day). The results indicated that the explicit arousal alcohol expectancy was strongly correlated with MAX. Also, the explicit sedation alcohol expectancy showed strong correlation with TQTY. The implicit positive alcohol expectancy had strong correlation with FREQ, TQTY, and MAX. The implicit arousal alcohol expectancy showed strong correlation with FREQ. Result of multiple stepwise regression analysis indicated that FREQ can be accounted by explicit positive and implicit arousal alcohol expectancies, TQTY can be accounted by explicit sedation and implicit positive alcohol expectancies, and MAX can be accounted by explicit and implicit positive alcohol expectancies. These results suggest that implicit alcohol expectancies can add the predictability with explicit alcohol expectancies. The effects of the expectancy challenge intervention on alcohol dependent inpatients were tested in the last section. The explicit positive and arousal alcohol expectancies significantly decreased while the explicit negative alcohol expectancy increased. The implicit alcohol expectancies did not change significantly, except implicit positive alcohol expectancy. These results suggest that implicit memory association might be an important process feature of alcohol expectancy, distinct from those assessed by existing questionnaires. The result also highlights the importance of the preventive approach, such as alcohol expectancy challenge, can prevent alcohol related problems when it is implemented before drinkers form a particular strong implicit alcohol expectation.
