Wilson's (1984)biophilia hypothesis predicts that people's psychological health is associated with their relationship to nature. Two studies examined associations among nature connectedness, well-being, and mindfulness in samples of undergraduate students while socially desirable responding was controlled. Significant associations emerged among measures of nature connectedness and indices of well-being (in Study 1 and Study 2) and mindfulness (in Study 2). Results are discussed in relation to possible mediators and moderators of the association between nature connectedness and mental health.
