Brief Summary

This is a 4-year randomized, controlled study to test the efficacy of the CHOICES4Health-T (C4H-T) delivered by a computerized tablet, CHOICES4Health-C (C4H-C), delivered by a counselor, and brief advice (BA), on reducing preconception substance-exposed pregnancy risk (i.e. drinking below risk levels; tobacco and marijuana cessation; effective contraception use) among women (aged 18-44) presenting to the 13 primary care clinics that serve adults within the Harris Health System. Given the natural fit between contraceptive and HIV prevention counseling the CHOICES4Health interventions will also target HIV sexual risk behaviors.

Outcome Measures

Primary Outcomes (6)

• Change in risk of alcohol-exposed pregnancy (AEP) as measured by self-reported daily standard drinks, vaginal sex, and use of contraception on the Timeline Followback calendar.

  Risk of AEP is defined as any risk drinking (\>3 drinks/day or \>7 drinks/week on average) and any occurrence of vaginal sex with no use or ineffective use of contraception in the assessment period. Self-reported daily alcohol use (in standard drinks), vaginal intercourse, and contraception (effective use) data from the Timeline Followback will be used to calculate risk of AEP for the previous 90 days. Change in Risk of AEP will be examined at 3-, 6-, and 9-months post-intake. A participant will be considered at risk of AEP at each of the 3-, 6-, and 9 month timepoints if the participant had any occurrence of vaginal sex without the use of effective contraception and had more than 3 standard drinks on any day or more than 7 standard drinks per week on average in any 30 day period in the previous 90 days. Risk of AEP will be a dichotomous outcome (at risk of AEP or at reduced risk of AEP).

  3, 6, and 9 months

• Change in risk of tobacco-exposed pregnancy (TEP) as measured by self-reported daily number of cigarettes, vaginal sex, and use of contraception on the Timeline Followback calendar.

  Risk of TEP is defined as currently smoking cigarettes (at least weekly use) and any occurrence of vaginal sex with no use or ineffective use of contraception in the assessment period. Self-reported data from the Timeline Followback will be used to calculate risk of TEP for the previous 90 days at 3-, 6 , and 9 months post-intake. A participant will be considered at risk of TEP at each of the 3-, 6-, and 9 month timepoints if the participant had any occurrence of vaginal sex without the use of effective contraception and she had at least weekly smoking in any 30 day period in the previous 90 days. Risk of TEP will be a dichotomous outcome (at risk of TEP or at reduced risk of TEP).

  3, 6, and 9 months

• Change in risk of marijuana-exposed pregnancy (MEP) as measured by self-reported marijuana use, vaginal sex, and use of contraception on the Timeline Followback calendar.

  Risk of MEP is defined as any day with marijuana use and any occurrence of vaginal sex with no use or ineffective use of contraception in the assessment period. Self-reported data from the Timeline Followback will be used to calculate risk of MEP for the previous 90 days at 3-, 6- , and 9 months post-intake. A participant will be considered at risk of MEP at each of the 3-, 6-, and 9 month timepoints if the participant had any occurrence of vaginal sex without the use of effective contraception and had any day with marijuana use in any 30 day period in the previous 90 days. Risk of MEP will be a dichotomous outcome (at risk of MEP or at reduced risk of MEP).

  3, 6, and 9 months

• Change in risk drinking as measured by self-reported number of standard drinks on the Timeline Followback calendar.

  Risk drinking is defined as drinking more than 3 standard drinks on any day or drinking more than 7 standard drinks in a week on average in the previous 90 days. Self-reported data from the Timeline Followback will be used to calculate risk drinking for the previous 90 days at 3-, 6-, and 9-months post-intake. Risk drinking will be a dichotomous outcome (yes or no).

  3, 6, and 9 months

• Change in cigarette smoking as measured by self-reported number of cigarettes smoked each day on the Timeline Followback calendar.

  Cigarette smoking is defined as at least weekly cigarette smoking in the previous 90 days on the Timeline Followback calendar at 3-, 6-, and 9-months post-intake. Cigarette smoking will be a dichotomous outcome (yes or no). In addition, smoking will be validated using biological test to assess cotinine levels.

  3, 6, and 9 months

• Change in marijuana use as measured by self-reported use for each day on the Timeline Followback calendar.

  Marijuana use is defined as any day with any marijuana use in the previous 90 days on the Timeline Followback calendar at 3-, 6-, and 9-months post-intake. Marijuana use will be a dichotomous outcome (yes or no). In addition, marijuana use will be validated using a biological test to assess Tetrahydrocannabinol (THC) levels.

  3, 6, and 9 months

Brief Advice

ACTIVE COMPARATOR
