This study examines how different efficacy constructs – self efficacy, personal outcome expectancy, collective efficacy, and collective outcome expectancy – independently influence willingness to engage in personal energy conservation behavior and support for policies to address climate change. Data from a representative, cross-sectional survey of 23 countries, European Social Survey Round 8, was analyzed to test the relationship. Overall, the results demonstrated that self efficacy, personal outcome expectancy, and collective outcome expectancy were all positively associated with both behavioral intention and policy support. Results regarding collective efficacy were unstable. The results demonstrate the importance of clearly distinguishing different constructs of efficacy beliefs from each other and suggest how climate change communication efforts may benefit from focusing on particular efficacy factors.

这项研究研究了如何构建不同的功效-自我功效，个人预期成果，集体功效和集体成果预期-独立影响参与个人节能行为的意愿以及对解决气候变化政策的支持。对来自23个国家的代表性横断面调查（欧洲社会调查第8轮）的数据进行了分析，以检验这种关系。总体而言，结果表明，自我效能感，个人预期成果和集体预期成果均与行为意愿和政策支持均呈正相关。关于集体功效的结果不稳定。
