理解幸福和积极因素与亲环境之间的关系对于推动社会可持续发展有重要的现实意义。为探究影响亲环境行为的积极前因, 研究聚焦于心理丰富的幸福取向, 通过10个子研究(N = 2979)考察了心理丰富对亲环境行为的影响及其潜在机制和边界条件。结果发现, 心理丰富程度越高, 人们越愿意为环保做出努力和行为改变(研究1.1~1.4), 而这是因为心理丰富提高了自我扩展水平(研究2.1~2.4), 并且在个体将自然看作比自我更渺小时, 自我扩展对亲环境行为的预测作用更显著(研究3.1~3.2)。研究结果揭示了幸福对亲环境行为的积极作用, 为推动人们参与构建可持续发展社会提供了启示。

Pro-environmental behavior, such as saving energy and taking public transportation, is beneficial to protecting the environment. Previous studies suggested that personality traits, environmental-related values, beliefs, affection, and norms are antecedents of pro-environmental behavior. However, protecting the environment is also rooted in motives for happiness and well-being. Generally speaking, there are three different types of well-being in positive psychology, namely hedonia, eudaimonia, and psychological richness. Based on different conceptions of well-being, research has shown that hedonic values were negatively related to pro-environmental behavior. Eudaimonic values were related to environmental values but it cannot directly predict pro-environmental behavior. Given it’s a new conception, the relationship between psychological richness and pro-environmental behavior is still absent. Thus, the present study aimed at exploring how psychological richness would influence pro-environmental behavior as well as its underlying mechanism and boundary conditions.

To reach the goals, we conducted ten studies with different experimental manipulations of psychological richness, multi-source participants, and various assessments of pro-environmental behavior. In correlational Study 1.1, we tested the link between psychological richness and pro-environmental behavior. In experimental Study 1.2~1.4, we manipulated psychological richness by recalling past memory and making the perspective change to explore its potential influence on pro-environmental behavior. In Study 2.1~2.4, the measurement-of-mediation design and experimental-causal-chain design were used to examine the mediating role of self-expansion. Based on the cross-sectional Study 2.1, in Study 2.2 we randomly assigned participants to the psychological richness condition and control condition to complete the task, and investigated whether psychological richness affected personal self-expansion. In Study 2.3, self-expansion was manipulated to explore its effect on pro-environmental behavior. To support our model, Study 2.4 was conducted to test whether psychological richness facilitates pro-environmental behavior through self-expansion. To investigate the moderating effect of nature-self size, we manipulated psychological richness in Study 3.1 and conducted a cross-sectional survey in Study 3.2.

As predicted, the present study found that both psychologically rich life and state psychological richness were positively related to pro-environmental behavior. Results indicated that psychological richness motivates people to engage in pro-environmental activities. The increased self-expansion was the reason why people experiencing psychological richness were more willing to protect the environment. Lastly, the results also demonstrated the moderating effect of nature-self size on the association of self-expansion and pro-environmental behavior.

Overall, the results extend the research on the effects of psychological richness on personal growth and sustainable social development. First, it suggested that pursuing well-being and behaving pro-environmentally were not in conflict. Namely, living a psychologically rich life motivates people to protect the environment. Second, message framing that promotes psychological richness could encourage individuals to engage in environmentally friendly activities.
