Personality and pro-environmental engagements: The role of the Dark Triad, the Light Triad, and value orientations

This study aims to investigate the associations between the Dark Triad personality (DTP), the Light Triad personality (LTP), and pro-environmental behavior (PEB), and the mediating roles of value orientations (biospheric, egoistic, and altruistic values) in these relationships. 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 pro-environmental behavioral intentions and past PEB via biospheric value orientation. Implications are discussed.
