As robustness checks, we reran the mediation analysis with emotional well-being as the dependent variable, perceived knowledge as the independent variable, actual knowledge as a covariate, and sense of control as the mediator. This analysis also yielded a significant indirect effect of perceived knowledge on emotional well-being through sense of control (95% CI [.07, .10]). We also reran the mediation analysis with actual knowledge, the demographic and economic variables and their interaction terms with perceived knowledge as covariates. This again yielded a significant indirect effect of perceived knowledge on emotional well-being through sense of control (95% CI [.02, .11]).
