Intranasal oxytocin increases positive communication and reduces cortisol levels during couple conflict


Ditzen, B; Schär, M; Gabriel, B; Bodenmann, Guy; Ehlert, Ulrike; Heinrichs, M (2009). Intranasal oxytocin increases positive communication and reduces cortisol levels during couple conflict. Biological Psychiatry, 65(9):728-731.

Abstract

BACKGROUND: In nonhuman mammals, the neuropeptide previous oxytocin term has repeatedly been shown to increase social approach behavior and pair bonding. In particular, central nervous previous termoxytocinnext term reduces behavioral and neuroendocrine responses to social stress and is suggested to mediate the rewarding aspects of attachment in highly social species. However, to date there have been no studies investigating the effects of central previous oxytocin term mechanisms on behavior and physiology in human couple interaction.

METHODS: In a double-blind placebo-controlled design, 47 heterosexual couples (total n = 94) received previous oxytocin term or placebo intranasally before a standard instructed couple conflict discussion in the laboratory. The conflict session was videotaped and coded for verbal and nonverbal interaction behavior (e.g., eye contact, nonverbal positive behavior, and self-disclosure). Salivary cortisol was repeatedly measured during the experiment.

RESULTS: Oxytocin term significantly increased positive communication behavior in relation to negative behavior during the couple conflict discussion (F = 4.18, p = .047) and significantly reduced salivary cortisol levels after the conflict compared with placebo (F = 7.14, p = .011).

CONCLUSIONS: These results are in line with animal studies indicating that central previous oxytocin term facilitates approach and pair bonding behavior. Our findings imply an involvement of previous oxytocin term in couple interaction and close relationships in humans.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
