Alcohol expectancy theory, Perceived self-efficacy, Perceived family support, Perceived friend support, Logistic regression model


This research was survey research aiming to study factors affecting decision on consuming alcoholic beverages among undergraduate Science students, Prince of Songkla University, Hatyai Campus. The sample of this study was a group of 350 students, and the sample size was calculated using the formula for the proportion estimation of stratified sampling. To collect data, a questionnaire consisting of demographic and related factors was used. The related factors of interest in this study included the expectations of positive and negative outcomes of consuming alcoholic beverages, perceived self-efficacy, perceived family support, and perceived friend support. The Cronbach’s alpha coefficient for all questions ranged from 0.71-0.88. The results showed that gender, age, year of study, accumulated grade point average (GPAX), monthly income, current housing, and the perceived family support did not affect the decision to consume alcoholic beverages among students. On the other hand, the expectations of positive and negative outcomes, perceived self-efficacy, and perceived friend support were significantly associated with the alcohol-drinking decision. Moreover, the logistic regression model proposed in this study to predict the chance of alcohol-drinking decision yielded 75.40% of correct prediction.
