Recent reviews of MFT literature have shown a failure to address mental hea
lth issues of the aging. Chief among these issues is depression, one of the
most common psychological disorders found in older people. Although the re
lationship between depression and aging is a well-researched topic, few stu
dies approach this common problem from a systemic perspective. Using data f
rom a national survey of preretirement- and retirement-aged couples, this p
aper discusses the association between depression and marital quality in ma
ture marriages as well the possibility of mediating variables such as the p
ersonality construct hardiness. Implications for marital therapy with older
couples experiencing depression and future research are discussed.
