Nourish what you own: psychological ownership, materialism and pro-environmental behavioral intentions

Purpose Researchers have become increasingly interested in the construct of psychological ownership in recent years. The purpose of this paper is to extend the target of psychological ownership to planet Earth as a whole and investigate its relationship with materialism and pro-environmental behavioral intentions. Design/methodology/approach The paper is based on a survey with 236 college students from a public university in the Southeast of the USA. The model fit from a confirmatory factor analysis is very satisfactory. Mediation of psychological ownership for the planet is formally tested using structural equation modeling (SEM) and Hayes' (2013) macro for SPSS. Findings The findings of this paper support the expectation that both the individual (my planet) and the collective-oriented dimensions (our planet) of individual-level psychological ownership are positively related to recycling intentions and the intention to purchase green products. Further, formal mediation tests show that psychological ownership for my planet, but not for our planet, mediates the relationship between material values and pro-environmental behaviors.
