The investigators propose to use obstetric-gynecological clinics to conduct a randomized clinical trial that would compare two SBIRTS (Screening, Brief Intervention, Referral and Treatment), delivered either by a trained nurse or by computer, to usual care (a control condition). As part of this trial, the investigators will include outcomes that allow us to assess the cost effectiveness of these three conditions.
Aim 1: To assess whether SBIRT, based upon motivational interviewing and delivered either by computer or a trained nurse, leads to decreased use of a subject's primary drug of abuse. Hypothesis #1a: Referrals based upon motivational principles and delivered by computer, as compared to usual care (health brochure with treatment resources), will lead to greater reductions in a woman's primary substance of abuse. Hypothesis #1b: Referrals based upon motivational principles and delivered by nurse, as compared to usual care (health brochure with treatment resources), will lead to greater reductions in a woman's primary substance of abuse. Aim 2: To determine whether SBIRT based upon motivational interviewing and delivered either by computer or by a nurse will promote substance abuse treatment utilization for the primary drug of abuse. Hypothesis #2a: Treatment utilization (eg. treatment initiation, attendance, use of quit-line or medication) will be higher if a woman receives the computer delivered brief intervention than if she receives usual care only. Hypothesis #2b: Treatment utilization (eg. treatment initiation, attendance, use of quit-line or medication) will be higher if a woman receives the nurse delivered brief intervention than if she receives usual care only. Secondary Aim 3: To evaluate whether SBI leads to a decrease in HIV/AIDS risk Hypothesis #3: Rates of sexually transmitted diseases, injection drug use and risky sexual behavior will be lower at follow up for subjects who receive either computer or a nurse delivered brief intervention than usual care subjects. Secondary Aim 4: To compare the relative cost-effectiveness of the three interventions. Hypothesis #4a: Screening and usual care will be the most cost-effective intervention method when the value of an additional unit of effect for the given individual's outcome is relatively low. Hypotheses #4b: Screening, and a brief intervention delivered by computer, will be the most cost-effective treatment method when the value of an additional unit of effect is relatively high. Hypotheses #4c: Screening, and a brief intervention delivered by a nurse, will be less cost-effective than a brief intervention delivered by computer.

Days Per Month of Primary Substance Use
Participants completed a timeline followback at each assessment, reporting days of primary substance use. Outcomes reported are raw means and standard deviations.
Time frame: 7 non-overlapping monthly intervals from baseline to month 6
Treatment Utilization
Treatment utilization assessed via participant self-report at each follow-up interview, and with the exception of self-help groups, verified with providers. We also reviewed the medical record for use of medication indicative of treatment (e.g., nicotine replacement therapy).
Time frame: baseline to 6 months
Rates of STDs
rates of incident std's per patient's medical records
Time frame: baseline to 6 months
Mean Cost for Each Intervention
The data table includes the mean cost for implementation of each intervention from the societal perspective. The costs do not include the research costs
Time frame: 6 months
