Stress shared by same-sex couples can have negative health impacts, according to a recent study.

New research by Allen LeBlanc, Health Equity Institute Professor of Sociology at San Francisco State University, studies how "minority stress" -- which results from being stigmatized and disadvantaged in society -- affects same-sex couples' stress levels and overall health. LeBlanc asserts that the health effects of minority stress shared by a couple can be understood as distinct from individual stress, a new framework in the field.

"Stress research has traditionally focused more on the individual experience of stress, which is very important, but social contexts get overlooked," LeBlanc said. "We are developing new ways of measuring stress at the couple level."

A gay man, for example, might feel individual stress if he conceals his sexual orientation from others, fearing discrimination in his workplace or rejection by his family. This situation can lead to couple-level stress if he asks that his partner hide their relationship, leading to new challenges affecting both men -- and the quality of their relationship.

LeBlanc suggests that future research must strive to better understand stressors that originate within the context of intimate relationships, and that such studies will advance the entire field of stress research.

"Relationships aren't inherently seen as problematic or challenging," LeBlanc said. "A lot of important work has been focused on what is helpful or positive about being in a relationship. There is longstanding literature, for example, demonstrating that people who are married tend to have better health than those who are not. But relationships are also a source of stress, and we can learn from that."

LeBlanc and his team are using their new framework of understanding shared stress to undertake the first study of couple-level minority stress. Hundreds of couples across the country will participate in a study designed to measure their individual and couple-level stress as distinct entities. A year later, the couples will complete a second survey, with the goal of learning how stress experiences and health change over time -- and the effects they have on a relationship. The data from this survey will allow the researchers to test their new theory of stress and health and help identify the kinds of stress that are most challenging for same-sex couples.

While LeBlanc's work focuses on minority stress among same-sex couples, he said the insights can be applied to other couples that experience minority stress, such as interracial couples, interfaith couples and couples in which one partner is significantly older than the other.

More details will be published in the February issue of the Journal of Marriage and Family.
