title: The theory of planned behavior as a model of heavy episodic drinking among college students.
abstract: This study provided a simultaneous confirmatory test of the theory of planned behavior (TPB) in predicting heavy episodic drinking (HED) among college students. It was hypothesized that past HED, drinking attitudes, subjective norms, and drinking refusal self-efficacy would predict intention, which would, in turn, predict future HED. Participants consisted of 131 college drinkers (63% women) who reported having engaged in HED in the previous 2 weeks. Participants were recruited and completed questionnaires within the context of a larger intervention study (see Collins & Carey, 2005). Latent factor structural equation modeling was used to test the ability of the TPB to predict HED. Chi-square tests and fit indices indicated good fit for the final structural models. Self-efficacy and attitudes but not subjective norms significantly predicted baseline intention, and intention and past HED predicted future HED. Contrary to hypotheses, however, a structural model excluding past HED provided a better fit than a model including it. Although further studies must be conducted before a definitive conclusion is reached, a TPB model excluding past behavior, which is arguably more parsimonious and theory driven, may predict HED among college drinkers better than a model including past behavior.
