This article focused on the study of individual and social-psychological determinants of a sense of efficacy on climate change mitigation. A correlational study investigated the predictive role of mindfulness, egalitarianism, risk concern, knowledge, and psychological sense of global community (PSGC). An online survey was administrated to US College students (N = 277). The main predictors of climate change response efficacy (CCRE) were PSGC and egalitarianism, followed by risk concern and climate knowledge. Among the facets of mindfulness, observing, and describing were the only ones associated with CCRE. The results found that mindfulness observing predicted response efficacy both directly and through the mediation of risk concern and sense of global community. Conversely, egalitarianism was not a significant mediator. Community psychologists should promote a sense of belonging to all humanity, and a more egalitarian view of the world, beyond risk concern, to increase climate efficacy. Training the skill of mindfulness observing could be a way to produce a sense of global community and affect climate change efficacy.
Keywords: climate change efficacy; climate change risk concern; critical consciousness; egalitarianism; observing; psychological sense of global community; sense of global community.
