Oxytocin selectively enhances the recognition of infant sadness in postpartum depression.

What Was Tested

The paper reports a study of Oxytocin, published as a randomized controlled trial.

BackgroundLittle is known about the role of oxytocin in the processing of positive emotional infant cues in mothers with PPD.ObjectivesWe therefore examined whether intranasal oxytocin influences postpartum mothers' processing of positive infant emotional cues, both visual (facial expressions) and auditory (laughter), and intended caregiving responses.DesignThis double-blind randomized controlled crossover study included 45 mothers, with 3- to 9-month-old infants, who exhibited clinically relevant scores on the Edinburgh Postnatal Depression Scale, with 35 mothers fulfilling the criteria of a major depressive episode assessed with the SCID-5.MethodsMothers participated in two randomized counterbalanced sessions, receiving oxytocin and placebo in separate sessions with a washout period in between.

Who Took Part

PubMed indexes the participants as infants and adults, women only.

How the Study Was Run

In design terms this was a randomized, double-blind, placebo-controlled and crossover study.

The participants were allocated by chance, so the Oxytocin group and the comparison group should start out alike.

Blinding on both sides kept the participants and researchers unaware of who received Oxytocin.

Some participants received a placebo instead of Oxytocin, giving a reference point.

Each person switched between Oxytocin and the comparison at some point, usually with a gap in between.
