Italia se considera un punto crítico del cambio climático en Europa y se ve afectada por numerosos eventos climáticos extremos y olas de calor severas y frecuentes, registrando un exceso de mortalidad de 18,000 muertes en 2022 debido a las altas temperaturas (Ministerio Italiano de Medio Ambiente y Seguridad Energética, 2023).

Italy is considered a hotspot for climate change in Europe and is affected by numerous extreme weather events and severe and frequent heat waves, registering an excess mortality of 18,000 deaths in 2022 due to high temperatures (Italian Ministry of Environment and Energy Security, 2023). Italian young people are experiencing a rapidly changing world, with natural, political, and economic instability (Ballester et al, 2023).
The aim of the PERSIST project is to pilot and measure the impact of a school educational intervention on youth climate-related emotions and to assess its efficacy in strengthening literacy on the climate crisis, applying pro-environmental behaviours, and promoting systems thinking in high school students in Italy. The project involved 273 students in ten different classes attending between grades 1 and 4 and aged between 13 and 18 at a scientific high school in Rome, Italy. These students engaged in three, two-hour sessions, with seasoned researchers, delving into an interactive educational model to enhance their understanding of the climate crisis. The sessions covered the causes and impacts of the crisis on human health, incorporating interactive elements such as brainstorming, games inspired by complex systems, and debates.

The intervention comprised three 120-minute sessions facilitated by public health residents, who had received prior training for this specific type of intervention. These sessions were conducted in ten high school classes, aiming to impart knowledge to students regarding the causes of the climate crisis, the human role in it, and its impacts on health. The teacher-centric approach was minimised, with a preference for group work, active discussions, complex systems-based games, and a question-oriented methodology. Through guided discussions, students could deduce answers, utilising complex systems models, brainstorming, and group activities.
To evaluate the effectiveness of the intervention, a questionnaire was deployed to gauge climate crisis literacy, climate-related emotions, and pro-environmental behaviours, while also gathering feedback on the overall appreciation of the program. The assessment of climate crisis literacy included questions about climate-related emotions (worry, fear, outrage, hope, and guilt) and pro-environmental behaviours, drawing from surveys conducted by Rooney-Varga et al. (2018) and Hickman et al. (2021). Additionally, a set of specifically crafted and validated questions was used to explore knowledge about the correlation between the climate crisis and human health, most of which required Likert scale responses, while others necessitated yes/no/do not know responses.
The survey was administered both before the intervention and at the conclusion of the last session to establish a baseline and measure any changes following the three lessons, thereby assessing the efficacy of the methodology. Of the administered questionnaires, 136 pairs of pre- and post-questionnaires were deemed valid, accounting for some missing pairs. Notably, mean knowledge scores regarding climate change impacts increased after the intervention (p<0.001; Cohen’s d = 0.39; 95% CI: 0.23 – 0.55). Similarly, mean knowledge scores concerning the health impacts of climate change demonstrated improvement with a medium effect size (p<0.001; Cohen’s d = 0.78; 95% CI: 0.57 – 0.99). Interestingly, there were no discernible differences in climate-related emotions between the pre- and post-intervention periods. This finding is noteworthy as it suggests that employing a specific methodology can enhance climate crisis literacy and foster positive attitudes without amplifying negative climate-related emotions.

Young people are facing natural, political, and economic instability with no action taken by decision-makers to mitigate or adapt to the climate crisis. This can lead to a loss of hope, eco-anxiety, or one of many other climate-related emotions. They are aware of the negative impacts of the climate crisis; this knowledge can often come with significant affective responses, such as psychological distress, anger, or despair. The results of our study showed that awareness can be increased without improving negative emotions with a controlled and interactive approach. Despite the limited sample, we believe that this kind of approach could be a way to empower the young generation.
Preliminary descriptive analysis suggests important improvements in knowledge and attitudes without increasing negative climate-related emotions. The success of the PERSIST project raises the hope that it will be implemented in other secondary schools and ultimately included in school curricula as part of civic education teaching, to train citizens who are aware and motivated to preserve the health of our planet and to raise pro-environmental behaviours in youth without generating or increasing negative emotions. As this project was a pilot project with a limited number of participants, a study with a greater cohort is desirable. It would also be of great value to have a control cohort.
Preliminary descriptive analysis indicates significant enhancements in both knowledge and attitudes, without escalation of negative climate-related emotions. The outcomes observed in the PERSIST project instil optimism regarding its potential replication in other secondary schools and eventual integration into formal educational curricula, particularly within the context of civic education. This initiative aims to cultivate an informed and motivated community dedicated to preserving the planet's health and fostering pro-environmental behaviours in youth, all while avoiding the generation or amplification of adverse emotional responses. Given the pilot nature of the project and its limited participant pool, a more expansive study with a larger cohort is recommended, along with the inclusion of a control cohort, to further validate and refine the findings.

Team made up of four residents in Public Health of the Università Cattolica del Sacro Cuore in Rome: Alessio Perilli, Gaia Surya Lombardi, Lorenza Nachira and Doris Zjalic. The team has been working on the topic of education in Planetary Health for both high school students and university students since 2021 and it is implementing a similar project on a national basis, in collaboration with the Psychology Department of Università degli Studi di Firenze. The team was supervised by Chiara Cadeddu, team chair of Planetary Health at Erasmus University in Rotterdam.
