Behavioral Intervention to Reduce Sexual and Injection Risks Among Female Sex Workers Who Also Inject Drugs in Mexico

Summary

The investigators propose a highly efficient four-arm (factorial) trial to simultaneously test the efficacy of two behavioral interventions aimed at:

* increasing condom use in the context of ongoing drug use and
* decreasing needle and paraphernalia sharing

among female sex workers who also inject drugs in two Mexican-U.S. border cities: Tijuana and Ciudad Juarez.

Conditions

• HIV
• HIV Infections

Interventions

BEHAVIORAL

Interactive injection and sexual risk intervention

This is a one-on-one intervention that incorporates elements of motivational interviewing (MI) and principles of Social Cognitive Theory (SCT) and Theory of Reasoned Action (TRA) to address the context of both, a) unsafe injection sharing and the extent to which syringes and other injection paraphernalia is shared; and b) unsafe sex and condom use with clients, and associated risks (e.g., HIV (Human Immuno-deficiency Virus), STIs (Sexually Transmitted Infections), pregnancy).

BEHAVIORAL

Interactive Sexual Risk Intervention

This is a one-on-one intervention that incorporates elements of motivational interviewing (MI) and principles of Social Cognitive Theory (SCT) and Theory of Reasoned Action (TRA) to address the context of unsafe sex and condom use with clients, and associated risks (e.g., HIV (Human Immuno-deficiency Virus), STIs (Sexually Transmitted Infections), pregnancy).

BEHAVIORAL

Interactive Injection Risk Intervention

This is a one-on-one intervention that incorporates elements of motivational interviewing (MI) and principles of Social Cognitive Theory (SCT) and Theory of Reasoned Action (TRA) to address the context of unsafe injection sharing and the extent to which syringes and other injection paraphernalia is shared.

BEHAVIORAL

Lecture-format presentation

60 minute lecture-format presentation on safer sex and safer injection based on CDC guidelines for HIV counseling, testing, and referral and materials from Mexico's National Center for AIDS Studies (CENSIDA). There are no theory-driven active skill building elements oriented towards safer sex or safer injection.
