Summary
This proposed study is to test whether Health Check-up for Expectant Moms (HCEM), a computer-delivered screening and brief intervention (SBI) that simultaneously targets sexually transmitted infection (STI) risk and alcohol/drug use during pregnancy, reduces antenatal and postpartum risk more than an attention, time, and information matched control condition among pregnant women seeking prenatal care.
