Abstract

Purpose of the study: Individual beliefs are known to be predictive of health. This study examines the co-construction of couple norms and links couples' shared beliefs about aging to future individuals' and couples' functional limitations.

Design and methods: Data from the 2008 and 2014 waves of the Health and Retirement Study (1,231 couples; age range = 51-90) were analyzed using latent variables that estimated shared and individual variance in beliefs about aging in 2008 and functional limitations at follow-up in 2014. Spouses' individual processes of physical activity and disease burden were modeled to contribute to couples' shared beliefs about aging and subsequent functional limitations. Models progressively controlled for indicators of partner selection, couples' shared health experiences, and similarities and differences in age.

Results: Couples' beliefs about aging predicted future functional limitations. The effect magnitude decreased but remained significant in all models. Physical activity predicted couples' future functional limitations but was largely explained by shared health experiences and similarities and differences in age for wives and husbands, respectively. Disease burden contributed to couples' shared beliefs about aging. Husbands' contributions were explained by partner selection, but wives' contributions remained significant in all models. The effect of couples' shared beliefs on change in couples' functional limitations was explained by couples' shared health experiences.

Implications: Beliefs about aging and health occur within the context of close relationships and shared experiences. Knowledge of couples' beliefs and health is necessary to support their individual and collective efforts to age successfully together.

Common fate model of couples’ self-perceptions of aging on future functional limitations with contribution of individual processes on shared processes. Note: Loadings within constructs are constrained to 1. Variances within constructs across gender are constrained to equal. Individual variances (i) were allowed to covary within gender and were tested for equality/inequality across gender.
