Alcohol expectancies, conduct disorder and early-onset alcoholism: negative alcohol expectancies are associated with less drinking in non-impulsive versus impulsive subjects.

Aims: Research suggests that positive alcohol expectancies promote excessive alcohol use while negative alcohol expectancies discourage excessive alcohol use. Evidence suggests that disinhibitory characteristics, such as conduct disorder and impulsivity, are associated with a general neglect of long-term negative outcomes. This study assessed whether negative expectancies would be associated more strongly with lower levels of alcohol use for low- compared with high-impulsive individuals.
