The personal benefits of authenticity are now well documented. However, in this paper we hypothesize that authenticity is not only beneficial to the person themselves, but that it also promotes prosociality and ecological sensitivity. This study used cross-sectional data from one hundred and twenty-nine Turkish participants, who completed Turkish version of the Authenticity Scale, The Environmental Behavior Scale, The Helping Attitudes Scale and The Self-Transcendence Scale. The findings reported here show that greater authenticity was associated with more favorable attitudes to helping others and engagement in pro-environmental behaviors. Furthermore, the present research explored, for the first time, the effects of self-transcendence. The results showed that the associations between authenticity and helping attitudes of altruism as well as receiving and giving were mediated by self-transcendence. Implications, limitations, and future directions are discussed in terms of humanistic perspectives on authenticity.PsychologyClinicalJournal article1752-91821069402700001Q441642
