Predictors of Pro-Environmental Behaviors in Adolescence: A Scoping Review

Today's adolescents will inevitably face the negative effects of climate change and will need to engage in pro-environmental behaviors (PEBs) as part of the solutions. The primary objective of this scoping review was to identify the individual, peer and family, and school and community predictors of PEB in adolescence. The secondary objectives were to highlight the main types of PEBs, the main conceptual frameworks examined in adolescence, and the main research gaps mentioned in prior studies. A bibliographic search on multiple databases was conducted. Among the 2578 records identified, 209 were retrieved and assessed for eligibility, and 62 met the inclusion criteria (i.e., peer-reviewed primary research articles published in English in the last ten years with adolescent data). Results reveal a heterogeneous set of correlates with an imbalance favoring individual correlates. The most frequent PEBs in the reviewed studies were linked to energy and water conservation. The most frequent theoretical frameworks were the Theory of Planned Behavior and the Value-Belief-Norm Theory, while the most frequently highlighted research gap was the use of cross-sectional designs. These results can inform the targets of interventions aimed at increasing PEBs, which are fundamental aspects of the psychology of sustainability and sustainable development.
