IntroductionThe psychology of sustainability and sustainable development aims to contribute to the establishment of a culture of sustainability regarding the 2030 Agenda and its 17 sustainable development goals.MethodsIn this framework, this study examined the associations between acceptance of change and well-being (hedonic and eudaimonic sides), controlling for the effects of personality traits, in 284 Italian university students.ResultsAcceptance of change explained additional variance over personality traits regarding hedonic and eudaimonic well-being.DiscussionAcceptance of change could thus represent a promising well-being resource from the perspective of strength-based prevention, opening future perspectives to face the challenges of sustainable development, particularly concerning Goal 3 of the 2030 Agenda: “Good health and well-being.”
