Intranasal Oxytocin Investigated for Improving Couples' Conflict Resolution Skills

Oxytocin is a neuropeptide known for its role in fostering prosocial behavior, reducing negative affect such as fear and anxiety, and mitigating stress-induced addictive behaviors. These properties suggest a potential therapeutic application in enhancing interpersonal dynamics. Current approaches to couples conflict resolution often rely on behavioral therapies, which, while effective, may not fully address underlying physiological or neuroendocrine responses that can exacerbate tension. Investigating oxytocin's impact on these biological markers during conflict could offer a novel pharmacological adjunct to improve relationship functioning and emotional regulation during stressful interactions.

This study outlines a protocol to investigate the extent to which intranasal oxytocin affects couples' conflict resolution. Participants will receive a 40 IU dose of intranasal oxytocin administered intranasally prior to engaging in structured conflict resolution discussions. These discussions will be conducted in a controlled laboratory setting and meticulously videotaped to allow for detailed behavioral analysis of interaction patterns. The primary endpoints include objective measures of conflict resolution skills, alongside subjective reports of conflict experience, and assessments of physiological and neuroendocrine responses to the conflict, likely involving assays such as cortisol levels, oxytocin levels, and heart rate variability. A placebo control arm is implicitly part of the investigation to determine improvement.

This abstract describes the aims and methodology for a planned study investigating oxytocin's role in couples' conflict resolution. It does not present any empirical findings or results from the intervention. Therefore, no specific data, percentages, or p-values are available from this publication to report on the efficacy or outcomes of 40 IU intranasal oxytocin in improving conflict resolution skills or modulating physiological and neuroendocrine responses. The study is designed to gather this data in the future, and this abstract serves as a protocol description.
