  1. 01HumanSystematic reviewEfficacy outcome

    In a meta-analysis, intranasal oxytocin significantly reduced behaviors of attachment insecurity in neutral contexts, particularly attachment avoidance.

    1 context sentence
    Summary · context
    Here, we conducted - meta-analyses to estimate the associations between peripheral OT level (e.g., blood and salivary OT) and attachment (i.e., attachment dimensions and behaviors of attachment insecurity) and examine the effects of intranasal OT administration on behaviors of attachment insecurity.

Natural levels measured1

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.

    In a meta-analysis, peripheral oxytocin level was not significantly associated with attachment dimensions or behaviors of attachment insecurity.

    In plain wordsIn a pooled analysis, the body's own oxytocin level in blood or saliva was not linked to attachment anxiety, avoidance or insecure behavior.
