Full mediation 1: Drop direct effects from childhood SES (parental SES, books at home, school at age 16) and childhood health to well-being (quality of life or life satisfaction). Partial mediation: Add direct effects from childhood SES and health to well-being. Full mediation 2a: Add direct effect from books at home to quality of life. Full mediation 2b: Add direct effects from childhood SES to adult health. Full mediation 2c: Add direct effects from childhood health to adult SES
