Study of Ultrasound To Increase Parental Bonding in Women With Substance Use Disorders

1. A randomized trial of 3-dimensional vs. 2-dimensional ultrasound, comparing scores on the Maternal Antenatal Attachment Scale (MAAS), a validated instrument measuring maternal attachment as a marker of maternal bonding. The hypothesis is that 3-dimensional ultrasound is better at eliciting maternal attachment than 2-D 2. To assess changes in maternal confidence to stop using drugs and quit/reduce smoking with 3-D vs. 2-D ultrasound. Again, the hypothesis is that 3-D ultrasound will improve the woman\'s confidence to stop using substances. 3. To evaluate if 3-D ultrasound improves paternal attachment as measured by pre- and post- scores on the Paternal Antenatal Attachment Scale (PAAS). The hypothesis is that 3-D ultrasound will have a greater effect on PAAS scores than 2-D.
