“…When we consider the findings of the husband's reports of marital quality linked with his wife's reports of social support and mental health by nonshared environmental influences, the husband is strongly implicated as the source of the nonshared environmental influences on his wife's mental health. Analyses conducted by other members of the Twin Moms team using MZ difference scores offer support for this explanation (Towers, 2003)…”

Interpersonal relationships are important factors in mental health. A genetically sensitive design was used to examine associations among marital quality, adequacy of social support, and 2 aspects of positive mental health in a sample of 652 Swedish twin women and their families. There were 3 main findings. First, the covariance between relationships and positive mental health was partially accounted for by common genetic variance. Second, nonshared environmental influences played a substantial role in the covariance among the 3 constructs, with evidence for husbands being a source of this influence. Finally, different patterns of associations were found between relationships and 2 aspects of mental health, well-being and global self-worth, which shows how seemingly similar constructs can be differentially associated with relationships. Together, these findings emphasize the importance of genetically informed studies in family research and the role of the environment and interpersonal relationships in promoting and improving mental health.

“…In addition to including measurement error and short-term effects, the nonshared environmental influences consist of enduring factors that make each twin different. Other researchers from the Twin Moms project have made a strong case for the influence of spouses explaining a majority of the nonshared environmental variance in marital quality (Spotts, Neiderhiser, Ganiban, et al, 2004; Spotts, Pedersen, et al, 2005; Towers, 2003). Considering that the spouses of MZ twins are not very similar to each other (Lykken & Tellegen, 1993), spouses are likely to be a large source of differential experience for the twins.…”

Numerous researchers have examined gender differences in marital quality, with mixed results. In this study, the authors further this investigation by looking for genetic and environmental sources of variation in marital quality. The 1st aim of the study was to replicate previous findings of genetic and nonshared environmental influences on marital quality. The 2nd was to explore the etiology of gender differences in marital quality. The Virginia Adult Twin Study of Psychiatric and Substance Use Disorders sample of twin men and twin women was used. Genetic and nonshared environmental factors were again found to influence marital quality. Findings also suggest small differences between men and women in the levels of genetic and environmental influence on variance in marital quality. The men's reports of marital warmth and conflict were influenced by the same genetic factors, but women's reports of marital warmth and conflict were influenced by different genetic factors. Results are discussed in the context of previous research on social support and implications for future studies of the etiology of marital quality.
