This section presents several abstracts of studies about elderly couples. Couples that stay together for 20 years or more have been little studied. Fortunately, mature marriages are beginning to be given increased research attention. Marriage after the empty nest stage of the family life cycle can pose special challenges to mature couples. The articles in this section all have in common the investigation of various aspects of marital quality in mature marriages. Interestingly, what is commonly found is that relationship quality in long lasting marriages is influenced by variety of factors, most important of which is the commitment one has to one’s spouse. When commitment to spouse is high there tends to be high marital quality, satisfactory sexual interactions, and low mood disturbance in mature marriages. What is also interesting is that although there appears to be stability in functioning across time for marriages, mature marriages have their own unique challenges and need to be understood in context of this uniqueness. The last paper reviewed deserves special mention because this research identifies the impact of negative spousal support for women when dealing with failing health. It turns out that being married is not necessarily a mental health benefit for women diagnosed with breast cancer, and in any unsupportive environment can actually be to the women detriment. As always, the clinical implications of these findings are emphasized.
