An Empirical test of an expanded version of the theory of planned behavior in predicting recycling behavior on campus

Background: The study and promotion of environmental health behaviors, such as recycling, is an emerging focus in public health. Purpose: This study was designed to examine the determinants of recycling intention on a college campus. Methods: Undergraduate students (N=189) completed a 35-item web-based survey past findings and an expanded version of the Theory of Planned Behavior (TPB). Path analytic models were examined with bootstrapping method. Results: The path coefficients revealed that all of the direct paths were statistically significant except the direct path from descriptive norm to behavioral intention. The model explained 49.3% of the variance in recycling intention. The strongest predictors of campus recycling intention were moral obligation and behavioral attitudes. Discussion: The expanded version of the TPB proved to be a sound theoretical framework to study the determinants of recycling on campus. Overall, the model components had a large effect on recycling intention. Translation to Health Education Practice: Using behavior change theory to understand recycling behavior is prerequisite to evidenced-based recycling interventions. These findings should be used to guide campus recycling interventions. © 2012 Taylor & Francis Group, LLC.
