STUDY: Adult Romantic Relationships as Contexts of Human Development: A Multimethod Comparison of Same-Sex Couples with Opposite-Sex Dating, Engaged, and Married Dyads,” Glenn I.

WASHINGTON – Same-sex couples are just as committed in their romantic relationships as heterosexual couples, say researchers who have studied the quality of adult relationships and healthy development. Their finding disputes the stereotype that couples in same-sex relationships are not as committed as their heterosexual counterparts and are therefore not as psychologically healthy.

These results are from two studies featured in the January issue of Developmental Psychology, published by the American Psychological Association. This issue includes a special section that examines sexual orientation across the lifespan.

Both studies compared same-sex couples with opposite-sex couples on a number of developmental and relationship factors. The first study examined whether committed same-sex couples differ from engaged and married opposite-sex couples in how well they interacted and how satisfied they were with their partners. Evidence has shown that positive interactions improve the quality of relationships in ways that foster healthy adult development.

Researchers from the University of Illinois at Urbana-Champaign compared 30 committed gay male and 30 committed lesbian couples with 50 engaged heterosexual couples and 40 older married heterosexual couples, as well as with dating heterosexual couples. All the partners responded to a questionnaire that documented how positively they interacted with one another on a day to day basis. The couples were also observed during a laboratory task and were monitored for distress by skin conductance and heart rate.

Results showed that same-sex relationships were similar to those of opposite-sex couples in many ways. All had positive views of their relationships but those in the more committed relationships (gay and straight) resolved conflict better than the heterosexual dating couples. And lesbian couples worked together especially harmoniously during the laboratory tasks.

This was the first study to follow same-sex couples in legalized unions over a period of time. This type of design allows the researchers to monitor changes in the relationships and compare them with changes experienced by both same-sex couples not in civil unions and heterosexual couples. All the couples were comparable with respect to race/ethnicity and age at the time of the study.
