Introduction
Climate change refers to long-term changes in weather elements such as temperature and precipitation, primarily resulting from human activities, such as burning fossil fuels. These changes have negative impacts on individuals’ mental health. Mental health refers to effective interaction with others and dealing with conflicts. Research has shown that mental health is significantly affected by climate change. Climate change anxiety refers to the distress and worry due to the impact of climate change and having concerns about the future, which can directly and indirectly affect mental health through resilience and adaptation. Resilience is defined as an individual’s ability to cope with stress and challenges, and can act as a protective factor against the negative effects of anxiety. Adaptation is the ability to adapt to new environments and conditions and can help mitigate climate change anxiety. The present study aims to develop a model to examine the mediating role of resilience and adaptation in the relationship between climate change anxiety and mental health.
Methods
This is a correlational study using structural equation modeling (SEM). The study population consisted of all members of the Iranian Red Crescent Society in six provinces of Iran affected by climate change in 2024: Khuzestan, Hormozgan, Ilam, Kerman, Sistan & Baluchestan, and South Khorasan. Sampling was conducted using cluster random sampling and convenience sampling methods. Ten cities were selected from each province, and 25 questionnaires were distributed to each city. Of 1500 questionnaires, 1196 were deemed suitable for analysis. The inclusion criteria were informed consent to participate in the study, residency in the specified province, and not having consulted a psychologist or psychiatrist in the past year. The exclusion criteria were the unwillingness to continue participation in the study and the failure to answer more than five percent of questions. To gather data, the 25-item symptom checklist, the eco-anxiety scale, the Connor-Davidson resilience scale, and the adaptation questionnaire were utilized. In the adaptation questionnaire, symptom checklist, and eco-anxiety scale, a higher score indicates worse and more severe conditions. Pearson’s correlation test and SEM were employed to examine causal relationships among the variables. The results were analyzed in SPSS software, version 24 and Amos software, version 24.
Results
In this study, 1196 Iranian people participated. Their mean age was 33.25 years. In terms of educational levels, 177(14.8%) had lower than high school education, 350(29.3%) had a high school diploma, 132 (11%) had an associate degree, 455(38%) had a bachelor’s degree, and 82(6.9%) had PhD degrees. There was a significant positive relationship between climate change anxiety and mental health (P<0.01, r=0.41) and between adaptation and mental health (P<0.01, r=0.57), while a significant negative relationship was observed between resilience and mental health (P<0.01, r=-0.39). As presented in Tables 1 and 2, the indirect effect of climate change anxiety on mental health was significant through adaptation and resilience (P<0.001). Therefore, the findings of the research indicate that climate change anxiety can predict mental health both directly and indirectly through resilience and adaptation.
Conclusion
Climate change anxiety has significant negative effects on Iranian people’s mental health. In addition, the feelings caused by this anxiety can lead to a decrease in resilience and adaptation, which ultimately weakens the ability of people to adapt to new conditions. Therefore, it is necessary to pay attention to the psychological and social needs of people and provide support to reduce their anxiety related to climate change, so that they can adapt to the challenges more effectively. Considering the negative impact of climate change anxiety and the role of resilience and adaptation as mediating variables, it seems that strengthening resilience and adaptation can effectively improve the mental health of people.
