Prenatal Cocaine, Nasal Oxytocin, and Maternal Psychophysiology

University of North Carolina, Chapel Hill31 enrolled

Overview

The purpose of this research is to study the effects of nasal oxytocin administration on maternal behaviors that may be influenced by cocaine use during pregnancy. 32 mothers with prenatal use of cocaine during the current pregnancy will be studied at 3-6 months postpartum, when they will complete 3 study visits, a 2-week double-blind trial of twice daily nasal spray (oxytocin or placebo) and 4 telephone interviews. All information collected is confidential.

Participation for mothers when they are 3-6 months postpartum includes: * Visit 1: Questionnaires and interviews about participants' health, pregnancy, moods, psychological history and drug use during pregnancy and postpartum. * Visit 2: Pregnancy \& drug tests (results are confidential), blood samples and vital signs, video-taped mother-infant interaction, speech task, instruction re: using nasal spray (oxytocin or placebo) \& self-administration of first nasal spray dose, followed by 90 minutes of monitoring. * At-home nasal spray: Twice daily (before breakfast and supper) nasal spray self-administration for 14 days. * Visit 3: Pregnancy \& drug tests (results are confidential), blood samples and vital signs, video-taped mother-infant interaction, speech task, interviews and questionnaires about mothers' experience with the nasal spray, and changes in mood or physical discomfort during the 2-weeks when taking the nasal spray. * 3 telephone interviews while subjects are taking nasal spray, and 1 post-trail telephone follow-up.

Outcomes

Primary Outcomes

The effects of a 2-week trial of twice nasal oxytocin compared with placebo on maternal sensitivity

Time frame: 2 weeks

Secondary Outcomes

The effects of a 2-week trial of nasal oxytocin compared with placebo on maternal reactivity to a social stressor indexed by change in vascular resistance from pre- to post-test nasal spray.

Time frame: 2 weeks

The effects of a 2-week trial of nasal oxytocin compared with placebo on maternal reactivity to a social stressor indexed by change in plasma norepinephrine.

Time frame: 2 weeks

The effects of a 2-week trial of nasal oxytocin compared with placebo on maternal reactivity to a social stressor indexed by self-reported affective ratings.

Time frame: 2 weeks
