Results from this study4

No result from this study comes from a test of the peptide.

Natural levels measured4

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelObservational studyOther

    In parents and infants, the body's own salivary oxytocin was individually stable and rose from before to after a play interaction.

    In plain wordsIn parents and infants, the body's own oxytocin in saliva rose after playing together.

    Summary
    Parent and infant's salivary OT was individually stable across assessments and showed an increase from pre- to post-interaction.
    2 context sentences
    Summary · context
    Fifty-five parents (36 mothers and 19 fathers) engaged in a 15-min interaction with their infants.
    Summary · context
    Baseline plasma OT was sampled from parents and salivary OT was sampled from parents and infants before and after play and analyzed with ELISA methods.

    This result measures the body's own Oxytocin. Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyOther

    Parental and infant oxytocin levels were significantly correlated at both assessments.

    In plain wordsParents' natural oxytocin levels were linked to their infants' natural levels.

  3. 03HumanEndogenous levelObservational studyOther

    Higher oxytocin levels in parent and child were related to greater affect synchrony and infant social engagement.

  4. 04HumanEndogenous levelObservational studyOther

    In parents and infants, parent-infant affect synchrony moderated the relation between parental and infant oxytocin, and the association was stronger under high affect synchrony.

    In plain wordsIn parents and infants, the link between their natural oxytocin levels was stronger when their emotions were more closely matched.

    Summary
    Parent-infant affect synchrony moderated the relations between parental and infant OT and the associations between OT in parent and child were stronger under conditions of high affect synchrony.
