Covariance structure models of expectancy

Summary

Alcohol expectancies partially mediate the link between sensation-seeking and alcohol consumption. Family history of alcohol abuse did not predict drinking outcomes in this college sample, and measurement overlap may inflate sensation-seeking and alcohol use correlations.

Area of Science:

  • Psychology
  • Addiction Research
  • Behavioral Science

Background:

  • Genetic, environmental, and cultural factors are broadly linked to alcohol abuse risk.
  • Existing risk factors show weak correlations with alcohol consumption, obscuring underlying mechanisms.
  • Understanding the pathways from risk factors to alcohol abuse is crucial.

Purpose of the Study:

  • To investigate the mediational role of alcohol expectancies in linking sensation-seeking and family history of alcohol abuse to alcohol consumption.
  • To examine the influence of stored alcohol information in memory.
  • To assess the impact of criterion contamination on sensation-seeking and alcohol consumption relationships.

Main Methods:

  • Covariance structure modeling was utilized in a college population.

  • Examined antecedent variables: family history of alcohol abuse and sensation-seeking temperament.
  • Assessed alcohol expectancies as a potential mediator.

    • Main Results:

    • Alcohol expectancies partially mediated the relationship between sensation-seeking and alcohol consumption.
    • Family history of alcohol abuse was not significantly related to drinking outcomes.
    • Potential inflation of the sensation-seeking and alcohol consumption relationship due to item overlap was identified.

    Conclusions:

    • Alcohol expectancies are a key mechanism linking sensation-seeking to increased alcohol consumption.
    • Family history may not be a direct predictor of alcohol consumption in this context.
    • Methodological considerations, like criterion contamination, are important in addiction research.
