Implementation of an Efficacious Intervention for High Risk Women in Mexico

May 26, 2015 updated by: Thomas L. Patterson, University of California, San Diego
This project seeks to determine the personal and organizational conditions that are most conducive to the widespread adoption by community-based organizations (CBOs) of effective programs for reducing the spread of HIV and other sexually transmitted infections (STIs). Taking a brief, single-session counseling program (called "Mujer Segura") that has been proven effective in reducing HIV and STIs in female sex workers who work in Mexican cities along the U.S. border, this project will study the implementation of the program in CBOs in 12 additional cities throughout Mexico to determine how best to ensure that the program remains true to the original model and retains its effectiveness. Mexico has been chosen because HIV is a global problem that respects no international borders, and because HIV prevention programs that can be implemented in settings with limited resources are urgently needed in many parts of the world.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Theory-based counseling (Mujer Segura)
Will consist of 40 FSWs at each of 12 clinics, randomized into this condition from a pool of 80 eligible participants.
Brief (35-minute) counseling intervention using techniques from Motivational Interviewing and principles of social cognitive theory (SCT) and theory of reasoned action (TRA).
Active Comparator: CENSIDA counseling program (didactic)
Will consist of 40 FSWs at each of 12 clinics, randomized into this condition from a pool of 80 eligible participants.
Didactic HIV and STI counseling involving some personal risk assessment and presenting appropriate information on methods of transmission and for avoiding or reducing the risk of infection. Based on a counseling manual disseminated by CENSIDA, Mexico's federal HIV-AIDS prevention agency.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Reduction in HIV and STI incidence relative to control group
Time Frame: 6 months
Female sex worker (FSW) participants will be tested at baseline and 6-month follow-up for HIV, syphilis, gonorrhea, and Chlamydia. Incidence rates for all infections at 6-month follow-up will be compared between the theory-based Mujer Segura group (N=40 per clinic) and the standard counseling group (N=40 per clinic).
6 months
Reduction in number of unprotected sex acts relative to control group
Time Frame: 6 months
Female sex worker (FSW) participants will be assessed at baseline and 6-month follow-up using self-report measures of frequency of protected and unprotected sex acts with male clients. Changes in frequency at 6-month follow-up will be compared between the theory-based Mujer Segura group (N=40 per clinic) and the standard counseling group (N=40 per clinic).
6 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Fidelity to Mujer Segura intervention model
Time Frame: 6 months
Counselors at each CBO will be assessed for their fidelity to the intervention protocol and assigned a numerical score. This number will be used to determine possible correlations between levels of fidelity and the efficacy of the Mujer Segura intervention at each clinic.
6 months
