Background: Bangladesh is one of the most climate change-vulnerable countries in the world, but to date, no valid quantitative study has measured eco-anxiety, the psychological distress that is unique to climate change fears, in the country using standard tools. The purpose of this study was to determine the extent and severity of eco-anxiety among the university students in Bangladesh and to explore the correlation between eco-anxiety and depression, anxiety, and stress.
Methods: The study used a cross-sectional survey design, targeting 520 university students who were randomly selected from four public universities in Dhaka and Chittagong, from January to March 2025. The Climate Change Anxiety Scale (CCAS) was used to assess eco-anxiety, which is a validated scale. The Depression Anxiety and Stress Scale-21 (DASS-21) was used to measure mental health outcomes. A structured questionnaire was used for the collection of sociodemographic and climate exposure information. The analysis was performed using descriptive statistics, Pearson correlations and multiple linear regression.
Results: Of the 520 participants, 68.5% (n=356) scored clinically meaningful eco-anxiety
(CCAS score ≥25). Mean CCAS score was 31.4 (SD=9.2). Eco-anxiety was significantly
positively correlated with depression (r=0.52, p<0.001), anxiety (r=0.61, p<0.001), and stress (r=0.48, p<0.001). Females, coastal and flood-affected region students, and personally affected students had significantly higher eco-anxiety scores (p<0.05). After adjustment for age, gender and socioeconomic status, eco-anxiety was a significant independent predictor of anxiety symptoms (β=0.41, 95% CI: 0.28–0.54, p<0.001).
Conclusion: Eco-anxiety is prevalent among university students from Bangladesh and is closely related to poor mental health. The findings are the first-ever validated data on eco-anxiety in Bangladesh and highlight the need to have a climate-informed mental health policy and targeted interventions for psychological distress in the climate-vulnerable population of South Asia.
