Socioeconomic determinants of psychological well-being: the role of income, income change, and income sources during the course of 29 years.

Background: Considerable evidence indicates that income and other measures of socioeconomic position are associated with a wide variety of health outcomes. The authors of a few studies have prospectively examined the association between socioeconomic position over the course of decades and health outcomes. The present study, covering almost three decades of the life course, examined the cumulative impact of different income measures on psychological well-being among adults.
