The proportion mediated by the specific indirect effect is calculated as the absolute value of the ratio of the specific standardized effect and the specific standardized effect plus the standardized effect of SEP on health (|ab/(ab+c’)|, MacKinnon et al., 1995). Significant effects are printed in bold.
