Reported marital harmony -- or conflict -- accounts for nearly ten percent of the variation in mental health self-assessments in a broad study of Australian adults

Many recent studies have examined the possible social determinants of mental health. In this study, Yeboah Asiamah-Asare and colleagues looked specifically at how one's marriage or past marital experiences may interact with self-described financial problems and mental health status.

To assess how these factors may be associated, the authors analyzed data gathered from 6,846 Australian adults responding to the most recent iteration of the Household, Income and Labour Dynamics in Australia (HILDA) survey.

The respondents were mostly older than 42 (61 percent), born in Australia (78 percent), and married (78 percent), with an almost even gender split (51 percent women). Approximately 7 percent had poor mental health as indicated by the survey. Two percent of the variation in mental health scores could be attributed to demographic characteristics: participants 60 and older tended to have higher mental health scores compared to participants younger than 25 years; being a woman, born outside of Australia, retired, and/or being a student was also associated with poorer mental health scores. Three percent of the variation in mental health scores could be linked to financial difficulty, with participants who said "yes" when asked if they experienced difficulties paying utility bills on time, pawned or sold some belongings, sought financial help from friends/family, or sought help from welfare/community organizations tending to score lower on mental health. Marriage and relationship perceptions accounted for ten percent of the variation in mental health scores, with participants who perceived their relationships as good and meeting their original expectations tending to have higher mental health scores. Conversely, participants who reported many problems in their marriage or relationship, very often wished they had not been married or got in the relationship, and reported loving their spouse very much were less likely to report better mental health status.

The authors note that this finding of love not being enough to boost mental health scores in people experiencing relationship difficulties was surprising and unexpected, and suggest further research to investigate possible confounding factors. They also underscore the importance of marriage and relationships in understanding mental health more holistically.

The authors add: "There is a need for more policy attention toward the social determinants of poor mental health especially nuptiality or relationship perceptions, which have received less policy and research attention in Australia."
