Recruitment, Eligibility Screening, and Enrollment
To be eligible for enrollment, individuals had to meet the following inclusion criteria: self-identify as female; be 18 or 19 years old; self-identify as Hispanic and/or black; be visiting a study health center; be deemed appropriate for the study by PP staff with regard to physical and mental health; indicate that they were not knowingly pregnant nor trying to become pregnant; and not previously enrolled in this or another TPP study. Study coordinators (PP staff) reviewed patient demographic information for upcoming appointments at study health centers and screened all 18- and 19-year-old female patients for eligibility. Only individuals who met the study eligibility criteria and provided informed consent were enrolled. Enrollment continued until the required sample size was reached based on pre-implementation power calculations.
