Residents’ reactance and their intervention strategies in the context of mandatory waste separation.

Mandatory policies for waste separation may induce residents’ psychological reactance, which always manifests as multiple negative emotions. This psychological reaction changes dynamically and may continuously harm municipal waste management. However, how this psychological reactance changes over time and how we can intervene in it still lacks exploration. To bridge this gap, the development trends of psychological reactance for different residents and the intervention effects of information publicity were theoretically analyzed based on psychological reactance theory and persuasion theory. A four-times tracing questionnaire survey of 200 general residents from Shanghai was launched, and the data were statistically analyzed using latent variable mixed growth modeling. The results show that: (1) Mandatory policies for waste separation can lead to three trends of psychological reactance among residents: growth mode, decline mode, and inverted U mode. The latter two of these categories account for a greater proportion of the population and may be influenced by values and cultural background. (2) In all three modes, normative and knowledge-based information publicity have a mitigating effect on the growing trend of psychological reactance, while the effect on their initial state is not significant. (3) The changing trend of residents’ psychological reactance to waste separation is dynamic. Information publicity can effectively alleviate the trend of residents’ psychological reactance. The findings provide a dynamic perspective on the negative outcomes of mandatory waste separation policies and are helpful for the government to develop more appropriate policies and interventions.
