AbstractDespite the global nature of environmental problems, research on environmental psychology has been mainly based on Western countries, and very limited studies looked into environmental psychological constructs and processes through a non‐Western cultural lens. The present study examined the psychometric properties of the short‐form Nature Relatedness Scale (NR‐6) and investigated culturally relevant mechanisms that facilitate the positive influence of nature relatedness on green purchase intentions among Filipinos. Two studies were conducted to attain these objectives. Study 1 (N = 504) validated the NR‐6. Confirmatory factor analysis yielded a stable unidimensional factor structure of NR‐6 with good data‐model fit and strong factor loadings. Study 2 (N = 366) tested a moderated mediation model indicating the mediating role of social responsibility on nature relatedness and green purchase intention relationship across the different levels of interdependent self‐construal. Results indicated that social responsibility mediated the positive impact of nature relatedness on the intention to buy green products among Filipinos. More importantly, results showed a significant moderating role of interdependent self‐construal such that the indirect effect of social responsibility was stronger among Filipinos with higher levels of self‐construal than those with lower levels. Implications, limitations, and future directions are discussed.
