E cological degradation threatens human survival, increasing the need to understand factors related to pro-environmental attitudes and worldviews. In a globalising world, new paradigms arise as central to social sciences, including the New Ecological Paradigm (NEP) and the multicultural identities of individuals raised between the cultures, third culture kids (TCKs). NEP is an ecocentric perspective that stresses the interdependence between nature and humans, opposite to anthropocentrism. TCKs' exposure to cultural diversity during developmental years might support global issues engagement and ecocentric worldviews. The present study focused on non-Western TCKs (N = 399; mean age 21 years), aiming to explore whether multicultural identity configurations (integration, categorisation, compartmentalisation), values dimensions (self-transcendence, openness and conservation) and global mindset predicted ecocentric and anthropocentric worldviews. The results demonstrated that TCKs were ecocentrically inclined. The path model revealed that ecocentrism could be directly positively predicted by integrated multicultural identity, self-transcendence and a global mindset. Anthropocentrism was predicted by multicultural identity categorisation and conservation values. Also, values of self-transcendence and openness buffered the impact of compartmentalisation and categorisation on ecocentrism and anthropocentrism. This study set innovative directions in multiculturism and environmentalism discourse through understanding a multicultural identity's relationships with pro-environmental attitudes.
