Predicting binge-drinking among college students: Daily stress and Facebook posting tell the story
MetadataShow full item record
This dissertation proposed a conceptual model predicting binge drinking among college students, based on reasoned action theory (the most recent version of theory of planned behavior, [TPB]). The study conducted a two-wave online survey with predictors and the drinking behavior measured separately at two different time points within two-weeks. In the Wave 1 (Time 1) survey, 282 undergraduate students at a large public university answered questions assessing key predictors and individual characteristics. Two weeks later in the Wave 2 (Time 2) survey, 173 participants returned and answered their drinking behavior since Time 1. Findings from logistic regressions suggest that more favorable attitudes toward and more positive subjective norms of drinking increase the likelihood to binge drink; perceived ease of drinking less reduces the likelihood to binge drink, while perceived controllability does not; risk perception is not a significant predictor of binge drinking; students with higher stress are more likely to binge drink, but those with higher loneliness are not; exposure to prevention messages and social support do not predict binge drinking; alcohol-related social media use reinforces positive attitudes toward drinking which, in turn, increase the likelihood to binge drink. Implications of findings are discussed.
