Three parameters of marriage and their effects on the marital relation
ship in older adults are reviewed. Studies evaluating the impact of re
tirement on the marital relationship indicate that the retirement tran
sition is a ''generally positive'' experience for older adults who are
in good health, have an adequate income, and a history of marital com
patibility. Maintenence of this positive transition into retirement se
ems to be dependent on a balance between temporal structuring, purposi
ve activity, and a continuance of social contacts. Investigations of t
he impact of illness on the marital relationship indicate that the emo
tional or physical illness of either spouse can cause disequilibrium i
n the relationship. Decrements in the health of either spouse yield an
adverse effect on marital quality. Additionally, the impact is greate
r on perceptions of marital happiness for the healthy partner than for
the partner who is ill. Studies examining the impact of sexual dysfun
ction on the marital relationship are lacking. Scarcity of work in thi
s area appears to be due, in part, to prevailing cultural myths that o
lder adults are physically incapable of sex, have no sexual desire, an
d are physically unattractive. Yet, a few empirical efforts indicate t
hat sexual relations are not only common among elderly persons, bat th
at, particularly in the marital relationship, sexuality becomes an imp
ortant source of gratification in a world where gratification of any s
ort is diminishing.
