Climate change impacts on the mental health and wellbeing of young people: A scoping review of risk and protective factors

Abstract

Background/rationaleThe impact of climate change on the mental health of young people is poorly understood. Emerging evidence suggests that exposure to climate change exerts a disproportionate mental health burden on young people. An understanding of the risk factors (RFs) and protective factors (PFs) that affect the likelihood of mental health impacts arising from exposure to climate change is required to support youth wellbeing. Aims/objectivesThis review scopes the current research on what and how RFs and PFs are related to the mental health impacts of both direct and indirect exposure to climate change for young people. RFs and PFs were reviewed through the lens of ecological system theory. MethodsWe conducted systematic searches in four databases: PubMed, PsycInfo, Web of Science, and Scopus. Grey literature searches were conducted in ProQuest Dissertations, GreyLit.org, OpenGrey, and relevant organisations’ websites. We included 92 empirical studies focused on the RFs and PFs of the mental wellbeing under the impact of climate change of young people (0–24). We extracted data on study characteristics, type of climate change event, mental health outcomes, RFs and PFs, and associated ecological system level. ResultsThe current evidence base focuses predominantly on young people's experience of PTSD (k = 59), depression (k = 26), or anxiety (k = 17) mainly following exposure to singular climate change-related natural disaster events. Only four studies explored the impacts of climate change in general. Majority of the studies investigated RFs and PFs at the individual level and at the micro-system level. ConclusionsSeveral RFs and PFs were identified, such as coping strategies, family factors (e.g. parenting style), social support, community connection, and cultural identity. Positioning the mental health impacts of singular events within the broader context of ongoing and escalating climate change impacts will better inform the development of interventions that seek to build resilience among young people.
