Existing research shows that behavioural interventions can trigger pro-environmental behaviour change, but there is a lack of understanding around these interventions change behaviour. In response to recent research that calls for studies to systematically test links between interventions and the psychological determinants of behaviour, this study 1) develops and tests a pro-environmental behavioural change intervention in the field, and 2) empirically investigates which psychological determinants the intervention triggers, using a survey experiment. Results indicate that the intervention promotes the pro-environmental target behaviour by increasing commitment. Commitment is predicted by beliefs (unaffected by the intervention) and ascription of responsibility (triggered by the intervention). The present study has practical significance by proving the effectiveness of an easily implementable intervention, as well as theoretical significance by providing empirical evidence about the hypothesised connections between interventions and the psychological determinants of behaviour.

了解基于承诺的承诺干预如何鼓励环保游客行为

现有研究表明，行为干预可以引发有利于环境的行为改变，但人们对这些干预措施改变行为缺乏了解。最近的研究呼吁系统地测试干预措施与行为的心理决定因素之间的联系，为此，本研究 1) 开发并测试了现场的亲环境行为改变干预措施，2) 实证调查了干预措施的心理决定因素触发器，使用调查实验。结果表明，干预措施通过增加承诺来促进有利于环境的目标行为。承诺是通过信念（不受干预影响）和责任归属（由干预触发）来预测的。本研究通过证明易于实施的干预措施的有效性而具有实际意义，并且通过提供关于干预措施与行为的心理决定因素之间的假设联系的经验证据而具有理论意义。
