Adolescence is a time of development in the brain and microbiome, including the microbiome present in the mouth called the oral microbiome. Alcohol use often begins and escalates during adolescence, which can cause changes to the oral microbiome leading to changes in the brain. The alcohol specific changes to the oral microbiome and the brain may make adolescents more vulnerable to a lifelong struggle with alcohol use disorder. This study will collect (1) saliva to assess the composition of the oral microbiome and (2) brain measurements using magnetic resonance imaging (MRI) across adolescents who may or may not use alcohol. Findings from this study will help form a more thorough understanding of the biological consequences of adolescent alcohol use, with the long-term goal of informing novel prevention and intervention efforts.

This study involves testing how useful a technology-enhanced intervention is for pregnant people prescribed buprenorphine for the management of opioid use disorder. The intervention being studied is a brief therapy protocol and a mobile application. Participation involves four 60-minute biweekly (i.e., once every other week) therapy appointments during pregnancy, and three 30-minute therapy appointments monthly during the first three months after childbirth. The mobile application will be accessible for at least the duration of the study. Participants will also be asked to complete questionnaires at enrollment and again at 1-month postpartum and 3-months postpartum, and will be contacted approximately once a month to conduct a medication count. The total duration of the study is 6 months. Compensation is provided.
