Repeated Behavior and Environmental Psychology: The Role of Personal Involvement and Habit Formation in Explaining Water Consumption1

Extending existing theory in social and environmental psychology, we develop a model to study important predictors of water consumption behavior. Overall results provide support for the predictive ability of stimuli (e.g., environmental awareness), reasoned processes (e.g., personal involvement), unreasoned processes (e.g., habits), and situational factors (e.g., income) on water consumption behavior. Findings indicate that households with lower water usage display greater awareness of water conservation issues, are more highly involved in the decision to use water, and tend to form habits associated with lower usage levels. Furthermore, the results are consistent with past research that attitudes toward water usage appear to be poor predictors of water consumption behavior. After controlling for situational factors (e.g., household size), the findings substantiate the role of personal involvement and habit formation in explaining water consumption, lending further support to the adaptation and development of repeated behavior models in environmental psychology.
