A relationship between marital status on the one hand and various indi
cators of well-being and mental health on the other has been found in
a large number of studies. Typically, that the currently married have
been shown to enjoy the most favorable position, the divorced and wido
wed are generally worst off, and the never married in an intermediate
position. This paper provides an analysis of the consistency and gener
ality of this relationship: To what extent are there national differen
ce? Is the relationship stronger for men than women, as has been sugge
sted by several authors? And is there evidence for such a relationship
whatever measure of psychological well-being we use? Comparable inter
view data from 19 countries, including a few non-western ones, are use
d. The data are analyzed by ordinary linear regression methods, repres
enting marital status by means of dummy variables and controlling for
age and parenthood. At least some evidence of differences in psycholog
ical well-being between the currently married on the one hand and the
previously married and the never married on the other are found in pra
ctically all countries. On average the relationship between marital st
atus and well-being is quite similar for men and women. More striking
differences are found between well-being measures. The relationship wi
th marital status is weakest for positive affect and strongest for sel
f-reported happiness, with the results for negative affect and overall
life satisfaction falling in between.
