What This Study Did, in Plain Language
What Was Tested
Researchers studied Oxytocin in this randomized controlled trial publication.
Although oxytocin has been recognized for its affiliative and anxiolytic properties, dysregulation of this system may contribute to the link between depressed mood and insensitive maternal care in mothers with postpartum depression (PPD).
This double-blind, randomized, within-subject control study investigated the effects of intranasal oxytocin on caregiving behaviors, mood and physiology in mothers with (subclinical) PPD.
Who Took Part
By PubMed's age tags, the people studied were infants, young adults and adults, women only.
How the Study Was Run
The design is described as randomized and double-blind.
Because people in this Oxytocin study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.
Blinding on both sides kept the participants and researchers unaware of who received Oxytocin.
What Was Measured
The 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 even fulfilling the criteria of a major depressive episode assessed with the SCID-5.
The researchers assessed oxytocin's effects on maternal sensitivity, positive regard toward the infant, self-reported positive and negative mood, and physiological responses, including salivary cortisol, heart rate, and heart rate variability during mother-infant interactions.
