A Cognitive Model of Alcohol Use Among Taiwanese Adolescents: The Influence of Alcohol Expectancies and Drinking Refusal Self-Efficacy.

BACKGROUND

Drinking alcohol of adolescents is an important issue in Taiwan. The purpose of the research is to determine how drinking expectancy and drinking refusal self-efficacy influence drinking behavior among Taiwanese adolescents based on a cognitive model of alcohol consumption.

METHODS

In this cross-sectional study, a total of 908 students, selected from 10th to 12th grade of six high schools in Taiwan, were stratified randomly. Pearson correlation, and multiple regression analyses were conducted to examine the relationships among drinking expectancy, refusal self-efficacy, and alcohol use, including drinking frequency and drunkenness frequency.

RESULTS

There was significant positive relationship between drinking expectancies, and drinking and drunkenness frequency; and negative correlation between drinking refusal self-efficacy, and drinking and drunkenness frequency. Multiple regression analysis revealed that (1) tension reduction, sexual enhancement, social pressure, emotional relief, and opportunity to drink significant predicted drinking frequency (Adjusted R2 = 0.352, p < 0.001) and (2) tension reduction, increased confidence, cognitive enhancement, and social pressure significant predicted drunkenness frequency (Adjusted R2 = 0.226, p < 0.001).

CONCLUSIONS

Adolescents have positive outcome expectancies regarding increased drinking frequency. Under the pressure of social interaction, drinking was the most difficult to refuse. Alcohol expectancy and drinking refusal self-efficacy have both shown notable influences on Taiwanese adolescents.
