Longitudinal associations between chronic condition discordance and perceived control among older couples.

Chronic health conditions among individuals and their partners may diminish perceived control, particularly when these conditions are highly complex. We considered how chronic condition discordance (i.e., the extent that two or more conditions have nonoverlapping self-management requirements) at the individual level and the couple level (i.e., between spouses) was linked to health-related control and personal mastery across an 8-year period, and whether these links varied by age. The U.S. sample included 879 wives ( = 53.81 years) and husbands ( = 57.19 years) from three waves (2006, 2010, and 2014) of the Health and Retirement Study. Dyadic growth curve models controlled for age, minority status, education, own and partner baseline negative marital quality, and own and partner time-varying depressive symptoms, and number of chronic health conditions. Overall, both individual-level and couple-level degrees of chronic condition discordance were associated with initial levels of and rates of change in perceived control. When wives had greater individual-level discordance, they reported lower initial personal mastery. When husbands had greater individual-level discordance, they reported lower initial health-related control and faster declines in health-related control and personal mastery, and their wives reported faster declines in personal mastery. When there was greater couple-level discordance, wives reported lower initial health-related control. Age moderated the associations between wives' individual-level discordance and their own initial level of health-related control and rate of change in personal mastery. Interventions to improve later-life well-being may be enhanced by targeting increases in perceived control among individuals and couples managing complex patterns of chronic conditions.
