Objective: To examine psychological health as a mechanism linking economic pressure and marital instability in the early middle years to poor physical health in later life.
Background: Although previous research suggests that sustained stressful marital experience may lead to mental and physical health problems, little is known about how contextual factors, such as economic pressure, impact marital outcomes, and how changes in marital attributes influence health outcomes in a longitudinal and dyadic context.
Method: Utilizing an actor-partner interdependence model within a latent growth curve approach and prospective data from couples in enduring marriages, we examined the associations between family economic pressure, marital instability, and mental health over their early middle years (1989-1994) and subsequent physical health in later adulthood (2015). Analyses assessed a couple-level pathway and an individual pathway involving within-spouse and between-spouse effects.
Results: During the middle years, family financial difficulties were linked to reduced marital stability, which was associated with increased mental health challenges. The findings also reinforced the salient role of psychological distress for subsequent physical health outcomes as husbands' and wives' anxiety symptoms over their early middle years contributed to declines in their physical health outcomes in later adulthood. A partner effect was noted between husbands' anxiety and wives' physical health.
Conclusion: For couples, experiences of financial and marital stress in their early middle years can have long-lasting detrimental impacts on their physical health in later adulthood.
