Testing a tridimensional model of sustainable behavior: self-care, caring for others, and caring for the planet

This paper investigates the dimensions of sustainable behavior, with a particular focus on the aspects of self-care, caring for others, and caring for the environment. Its aim was to test the assumption that sustainable behavior not only encompasses pro-social and pro-environmental actions, as the current research acknowledges, but also behaviors that are directed toward self-preservation and care. A subscale of self-care specifically developed for this research was added to a series of previously validated instruments assessing altruistic, equitable, pro-ecological, and frugal behaviors to examine the personal, social, and physical environmental aspects of sustainable behavior. Responses from a sample of 290 participants confirmed the three-dimensional structure of sustainable behavior. Results suggest sustainability, understood as a chain of interdependences between the individual, society, and nature, begins with self-care and continues with caring for others, and with caring for the biosphere, which, in turn, affords for a more sustainable environment for the individual.
