Science, Arts, and National Mental Health: A Cross-National Panel Study of Intellectual Capital and Anxiety Prevalence

The dependent variable is national anxiety prevalence (NAP), measured as the population prevalence of anxiety and depression. The main explanatory variables capture national intellectual capital development in two domains: the sciences, measured through science, technology, engineering, and mathematics publication intensity per capita, and the arts, measured through social sciences, humanities, and creative arts publication intensity per capita.

The dataset also includes their interaction term to examine whether arts-based intellectual capital moderates the association between science-based intellectual capital and national mental health. Additional variables include education attainment among the population aged 15 and above, GDP per capita, R&D expenditure, health expenditure, internet diffusion, population size, economic freedom, political corruption, military spending, individualism, and OECD/developing-economy status.
