RESUMEN
BACKGROUND: Acknowledging the increasing worry over climate change and its psychological effects, the aim of this research is to clarify the dynamics between religiosity, climate anxiety and death anxiety, seeking to figure out the way religiosity mitigates the psychological effects of existential anxieties and climate related anxiety. METHODS: Using Google Forms, a questionnaire was developed and disseminated through a variety of messaging platforms, such as WhatsApp, Instagram, and Facebook Messenger. Through a snowball sampling technique, 763 participants were recruited in this cross-sectional during September 2023. RESULTS: The subsequent variables were adjusted in the moderation analysis: age, gender, and place of living. The results suggested that religiosity levels moderated the association between climate anxiety and death anxiety (Beta = 0.02, t = 1.97, p = .05, 95% CI 0.001, 0.035). At low, moderate, and high levels of religiosity, higher climate anxiety was significantly associated with more death anxiety. In addition, at low levels of climate anxiety, individuals with higher levels of religiosity (22.66) had more decreased levels of death anxiety compared to those with lower levels of religiosity (11.99). As climate anxiety levels increase, inverted patterns can be observed, with highly religious individuals showing higher levels of death anxiety than those with lower levels of religiosity. Overall, the relationship between climate anxiety and death anxiety was found to be weakest at low levels of religiosity and strongest at high levels of religiosity. CONCLUSION: Our findings suggest a possible beneficial effect of high religiosity at low levels of climate anxiety. This effect is reversed as climate anxiety starts to increase. Therefore, clinicians and policy-makers should bear in mind these complex interactions when designing strategies to mitigate mental health problems in the context of climate crisis.
