Developmental Differences Emerge in How Negative Consequences, Negative Expectancies, and Alcohol Use Relate Over...

Area of Science:

• Psychology
• Neuroscience
• Public Health

Background:

• Aversive learning theory posits that negative consequences of alcohol use (AU) reduce drinking.
• Existing research on this prospective association is inconsistent.
• Understanding mediators, moderators, and developmental differences is crucial for clarifying this process.

Purpose of the Study:

• To investigate the aversive learning process related to alcohol use.
• To identify mediators (negative alcohol expectancies) and moderators (sensitivity to punishment).
• To examine developmental differences in adolescence and young adulthood.

Main Methods:

• Longitudinal community sample (N=387) assessed annually for three years.
• Data collected during adolescence (ages 12-14) and young adulthood (ages 19-21).
• Prospective path models were used for analysis.

Main Results:

• In adolescence, negative consequences did not predict negative expectancies, but expectancies inversely predicted AU.
• In young adulthood, negative consequences positively predicted negative expectancies, but expectancies did not predict AU.
• Moderation by sensitivity to punishment was not supported.

Conclusions:

• Negative consequences are infrequent in adolescents, limiting their impact on expectancies, yet expectancies protect against AU.
• In young adults, negative consequences influence expectancies but lose their protective effect on AU.
• Alcohol consumption experiences appear to alter the development of expectancies and their influence on drinking behaviors.
