 This study evaluates a recently piloted, self-administered, computerized tool for reducing prenatal drinking that added novel components of drink size assessment and drink size feedback to traditional screening and brief intervention SBI. The bilingual English and Spanish electronic SBI or e-SBI will be adapted for use with non-pregnant women and a small trial of its efficacy will be conducted in two public health clinics. The effects of drink size assessment by itself and of depression as a modifier of e-SBI efficacy will also be studied. Study findings will help design a larger trial of e-SBIs efficacy for reducing prenatal alcohol use.
