Objectives: To study the mechanism of alcohol craving is difficult because it involves both cognitive and emotional processes, which are discordamtly influenced by patients¡¯ avoidance and denial. The objective of this study is to examine the mechanism of craving by evaluating responses of emotional component of alcohol-related stimuli, explicitly and implicitly.
Methods: The subject group was composed of 19 patients with alcohol dependence, 25 heavy drinkers, and 20 social drinkers. An implicit association test (IAT) measuring differential association of 2 target concepts (alcohol versus beverage) with 2 attribute dimensions (positive versus negative) was completed. Explicit evaluation of emotional valence and arousal for alcohol-related and control stimuli was also completed.
Results:The patient group reported alcohol-related stimuli more negatively on both implicit and explicit evaluation. In explicit arousal evaluation, they evaluated alcohol-related stimuli more arousing than control stimuli, whereos control groups did not. While the strength of alcohol-negativity association was not related to any clinical variables, the strength of alcohol-positivity association was related to the arousal level of alcohol related stimuli, the severity of alcohol dependence, and the mean drinking amount per occasion.
Conclusion: Alcohol craving can be regarded as negative emotion on both explicit and implicit levels in alcoholics. It seems that craving induced by alcohol-related stimuli may not be recognized by the patients but related to increased arousal or positive implicit evaluation of alcohol.
