A total of 312 individuals aged between 18 and 56 (M = 27.45; SD = 9.32) participated in this study. Path analysis showed that DTP was associated with an increase in the egoistic and with a decrease in the altruistic and biospheric value orientations. Additionally, LTP was associated with increased altruistic and biospheric value orientations. Last, LTP and DTP predicted proenvironmental behavioral intentions and past PEB via biospheric value orientation. Implications are discussed.eninfo:eu-repo/semantics/closedAccessDark TriadLight TriadValue orientationsBiospheric valuesPro-environmental behaviorArticle20310.1016/j.paid.2022.112036Q2WOS:0009335798000272-s2.0-85143871725Q1
