Prenatal behavioral risk screening by computer in a health maintenance organization-based prenatal care clinic

Abstract

Cigarette smoking, alcohol and drug abuse, and stressful life events are significant contributors to prematurity and low birth weight in the United States. Identification and treatment of pregnant women with these risk factors require obtaining complete and accurate psychosocial histories. The purpose of this study was to determine whether a computer interview developed by our staff is appropriate for assessing behavioral risk factors for adverse pregnancy outcomes and for educating pregnant women about healthy behaviors during pregnancy. This computer interview asks about pregnant patients' perceived life stressors, diet, use of cigarettes and alcohol, and abuse of drugs. The study population consisted of 201 medically insured Hispanic and non-Hispanic white women attending a health maintenance organization-based prenatal clinic. Almost all subjects rated the computer interview favorably. Medical record reviews were conducted to compare participants' reports of cigarette, alcohol, and drug use obtained from paper-and-pencil interviews with behaviors reported during the computer interview. Although self-reported rates of smoking did not differ between the two interview techniques, a much higher percentage of women reported alcohol and drug use during the computer interview. Study participants scored significantly higher on a test measuring knowledge of the effects of stress, diet, and substances of abuse on pregnancy than did a control group. Results demonstrated the potential value of computer-interactive software programs for assessing high-risk behaviors among pregnant women in this population and educating them about healthy behaviors during pregnancy.
