Abstract
Background The COVID-19 pandemic has profoundly affected global health systems and daily life, exacerbating vulnerabilities, particularly in Indonesia. This study investigates the impact of anxiety and education level on mental health, with spiritual intelligence as an intervening variable among post-COVID-19 patients in Indonesia. Methods A cross-sectional design was employed, analyzing data from 390 post-COVID-19 patients in Indonesia. Structured questionnaires were used to assess anxiety, education level, spiritual intelligence, and mental health. Results The findings indicate that anxiety significantly affects both spiritual intelligence and mental health, with spiritual intelligence acting as a mediating factor. Additionally, higher educational attainment is positively associated with enhanced spiritual intelligence and improved mental health outcomes. Conclusions The study underscores the importance of incorporating spiritual development practices into mental health interventions and educational programs to boost resilience and overall well-being in the post-pandemic era. These practices can help mitigate the adverse effects of anxiety and educational disparities on mental health.
