Oxytocin response to youth–mother interactions in clinically anxious youth is associated with separation anxiety and dyadic behavior

摘要

BackgroundAnxiety disorders are common in youth and cause significant distress and impairment to the individual and family. Oxytocin (OT), a nine amino acid peptide, is implicated in anxiety regulation and modulation of close interpersonal and attachment behavior. Anxiety disorders have been linked to low levels of salivary OT in youth. Research has also linked oxytocinergic functioning to social support, warm contact, and bonding, and indicated that contact with attachment figures stimulates OT response. We examined OT response to a brief, positive youth–mother interaction in clinically anxious youth. We investigated whether quality of the youth–mother interaction as well as the presence of particular anxiety disorders, are associated with youth OT response.
