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 37 patient-therapist dyads in psychotherapy for depression, synchrony of the body's own oxytocin changes was associated with effective treatment.

    In plain wordsIn patient-therapist pairs in depression therapy, matching changes in the body's own oxytocin were linked to effective treatment.

    Summary · context
    Five hundred eighty OT saliva samples were collected from 37 patient-therapist dyads on a fixed schedule over a 16-session ongoing randomized controlled trial for psychotherapy for depression.
    Summary · context
    Biological synchrony was operationalized as the correlation between changes occurring repeatedly over treatment in patient and therapist OT levels pre- to postsession.

  2. 02HumanEndogenous levelObservational studyOther

    In patient-therapist dyads in psychotherapy for depression, poorer baseline social functioning predicted lower synchrony of the body's own oxytocin changes.

    In plain wordsIn patient-therapist pairs in depression therapy, poorer social functioning at the start was linked to less matching of the body's own oxytocin changes.

    In patient-therapist dyads in psychotherapy for depression, lower synchrony of the body's own oxytocin changes predicted less reduction in depressive symptoms.

  4. 04HumanEndogenous levelObservational studyOther

    In patient-therapist dyads in psychotherapy for depression, oxytocin synchrony significantly mediated the association between social impairment and reduction in depressive symptoms.

    In plain wordsIn patient-therapist pairs in depression therapy, matching of the body's own oxytocin changes helped explain the link between social difficulties and symptom improvement.
