Abstract
Psychological perception of water scarcity, despite its strong correlation with water-saving behavior, has not been explored within major behavioral theoretical frameworks. This study develops an extended Theory of Planned Behavior (TPB) model incorporating psychological perception of water scarcity as an antecedent variable. This research paper investigates how scarcity perception impacts water-saving behavior by examining three mediating mechanisms: attitude, subjective norm, and perceived behavioral control. Additionally, it assesses the extended model's incremental explanatory power over the original model. Using data taken from China General Social Survey, this study uses structural equation model for path analysis and Bootstrap methods to test mediating effects. According to the findings, perceived scarcity is a significant predictor of all three main constructs of the Theory of Planned Behavior. The attitude path makes the biggest contribution as all three chained mediating paths are significant. The extended model demonstrates superior fit and predictive accuracy. This study establishes four specific objectives which include clarifying the theoretical positioning of perceived scarcity as a precursor variable within the behavioral model; outlining its specific psychological pathways to stimulate water-saving behavior; and providing targeted evidence for water-saving interventions. Policymakers must focus on effort on developing strategies that shape attitudes and enhance people’s self-efficacy to promote an overall shift residential water-saving behaviors.
