Who will take informed consent? {26a}
A 2-page study flyer is posted at the check-in desks of the treatment program’s outpatient and residential facilities. This flyer explains the study and provides contact information for the research coordinator and principal investigators. Additionally, research personnel review the opioid treatment program’s pregnancy census list weekly for new pregnant admissions or newly delivered clients. Staff at the opioid treatment program are asked to identify eligible individuals. All identified individuals are contacted by study personnel, either by phone or in-person, informed about the study, and asked if they are willing to participate. If they agree, an enrollment interview is carried out. Study personnel explain the purpose of the study, answer questions, and obtain written informed consent from those who meet study inclusion criteria. Those who consent to participate are provided with a copy of the consent form with contact details of the research team. Eligible individuals who do not agree to participate are asked to self-report basic sociodemographic information (e.g., age, education level, number of kids, and reason for refusal) to allow a comparison of enrolled and non-enrolled individuals. All staff responsible for obtaining consent are trained and certified in the protection of human subjects and study-specific consent procedures.
