Abstract
Objective: To evaluate the release of oxytocin as a biomarker of romantic‐partner attachment during couple recreation.
Background: To date, no studies have examined the impact of distinct types of recreation activities on the release of oxytocin. The Ecology for Family Experience framework, which highlights the divergent experience of family members, guided the experimental design.
Method: A total of 20 cohabitating or married couples were randomly assigned to one of the following two experimental groups: board games or art class. Urinary oxytocin was measured before and after the recreational activity. Analysis of covariance was used to determine group differences in oxytocin levels.
Results All groups released oxytocin during couple activities. Men in the art class demonstrated oxytocin response twice the level than other groups. Couples in the art class reported more partner touching than couples playing board games. A significant environmental impact was also identified.
Conclusion: Oxytocin is released during couple recreational activities. Some types of activities may contribute to higher release of oxytocin than others. Key factors may include touch, novelty, and sex.
Implications: Findings support the Ecology of Family Experience framework as a useful tool in examining factors of divergent and convergent couple experiences. Researchers should further explore the role of touch and environment in the release of oxytocin during couple activities.
