Control over What? Individual Differences in General versus Eating and Spending Self-Control
研究一般自我控制与饮食、消费领域特定自我控制的个体差异如何影响健康饮食和负责任消费结果，并提出新的测量方法以提高研究标准化和可比性，对公共政策干预设计有指导意义。
Public policy research is often directed at inducing welfare-enhancing behavioral change using interventions that provide consumers with helpful information and tools. The authors suggest that the effectiveness of such public policy interventions for relevant outcomes depend on individual differences in consumer self-control. The present research examines how healthy eating and responsible spending outcomes are influenced by low (vs. high) self-control at general and domain-specific levels. Important questions pertain to the theoretical basis of self-control individual differences and the relative efficacy of general and domain-specific measures in predicting eating and spending outcomes. The authors propose a new measurement approach to increase measurement standardization and the comparability of results in self-control studies and empirically demonstrate its value. Recommendations for public policy researchers and practitioners reflect the role of general and domain-specific individual differences in self-control and their implications for designing and testing effective interventions to improve consumer health and financial well-being.
