Eban II: Intervention for HIV Sero-Discordant Couples

Study Overview
=================
Brief Summary
-----------------
This study focuses on the implementation of an evidence-based HIV risk reduction intervention for HIV-serodiscordant, heterosexual African American couples (Eban II) in two geographic areas (Northern and Southern California - roughly, Alameda and Los Angeles Counties) that have a high prevalence of HIV infection and risk conditions among African Americans. The Specific Aims are as follows: To evaluate implementation of Eban for HIV serodiscordant African American couples in 10 CBOs in California. To do this, we will document the implementation process and identify barriers and facilitators to Eban's adoption and use by the CBOs. We will interview 200 staff at CBOs to obtain this information. To evaluate the effect of Eban on behavioral and biological outcomes among 180 couples, specifically incidents of protected sex, proportion of condom use, and incident sexually transmitted infections. Eban will be assessed using a randomized delayed enrollment (waitlist) control design to evaluate the impact of treatment on outcomes at posttest and 3-month follow-up (i.e., at these 10 CBOs, Eban will be conducted and offered to couples and evaluated for effectiveness - that is, how well it works in the real world.) To determine the cost-effectiveness of implementation of Eban, based on implementation costs and potential cost savings.

Detailed Description
-----------------
The HIV/AIDS epidemic continues to disproportionately affect African Americans. The rate of HIV among African American men is six times the rate for White men and the rate among African American women is almost 15 times the rate for White women. An estimated 56,300 new HIV cases was reported in 2006, of which 49% were among African Americans and 80% were from heterosexual transmission. Sexually transmitted infections (STIs) also disproportionately affect African Americans, further increasing the risk for HIV transmission. Despite the fact that HIV and STIs are primarily transmitted in the context of relationships, few interventions address HIV risk in couples. Furthermore, few evidence-based HIV prevention interventions have been implemented in community-based organizations (CBOs). Thus, there is a substantial need to strengthen the availability and use of relationship oriented prevention interventions in community-based treatment settings. This study focuses on the implementation of an evidence-based HIV risk reduction intervention for HIV-serodiscordant, heterosexual African American couples (Eban II) in two geographic areas (Northern and Southern California - roughly, Alameda and Los Angeles Counties) that have a high prevalence of HIV infection and risk conditions among African Americans. This study builds upon the multi-site, NIMH-funded Eban (a Yoruba term for fence) trial, which tested this culturally congruent intervention versus a control condition among 535 heterosexual HIV serodiscordant couples in four cities. Couples in the intervention had significantly reduced incidents of unprotected sex and an increased proportion of condom use compared to couples in the control condition. Statistical projections from that study suggest that if Eban participants had not received the intervention, six female and four males would have been infected in one year, and 25 females and 15 males would have become HIV-infected in the next 5 years. Based on these successful outcomes in a controlled trial, it is now appropriate to test the effectiveness of the intervention as delivered in community-based setting. Thus, we propose to conduct a study of implementation - a study of methods to promote the uptake of Eban into community-based organizations (CBOs). The Specific Aims are as follows: To evaluate implementation of Eban for HIV serodiscordant African American couples in 10 CBOs in California. To do this, we will document the implementation process and identify barriers and facilitators to Eban's adoption and use by the CBOs. We will interview 200 staff at CBOs to obtain this information. To evaluate the effect of Eban on behavioral and biological outcomes among 180 couples, specifically incidents of protected sex, proportion of condom use, and incident sexually transmitted infections. Eban will be assessed using a randomized delayed enrollment (waitlist) control design to evaluate the impact of treatment on outcomes at posttest and 3-month follow-up (i.e., at these 10 CBOs, Eban will be conducted and offered to couples and evaluated for effectiveness - that is, how well it works in the real world.) To determine the cost-effectiveness of implementation of Eban, based on implementation costs and potential cost savings. So please note, there are essentially two levels to this study -- first to see how well community agencies can implement or take up and execute the intervention (thus, the interviews with staff) - and the second, to see how effective Eban is in real world setting. We know it was highly effective in a controlled study but now we need to test how well it works in the real world(thus, the testing of the intervention with 180 couples). While doing this, we will also be examining the cost-effectiveness of the intervention in the real world setting.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Risk Reduction<br>The Risk Reduction group will receive the Eban II Intervention upon enrollment. This group will do the following: Provide HIV and STI test results First Interview Attend 8 sessions - 1 session per week Second interview occurs immediately following the 8th session with HIV and STI tests Third interview occurs 3 months after the 8th session with HIV and STI tests | Behavioral: Risk Reduction<br> <br> |
| Active Comparator: Waitlist<br>The Waitlist group will receive the same intervention after waiting for the Risk Reduction group to complete the entire intervention. Provide HIV and STI test results First Interview No sessions for 8 weeks Second interview and proof of HIV and STI status occurs after the 8 weeks from when you were enrolled Third interview occurs 3 months after the 8th session with HIV and STI tests The Waitlist Group will then be invited to participate in the Risk Reduction group activities. Attend 8 sessions - 1 session per week Fourth interview occurs immediately after the 8th session with HIV and STI tests Fifth interview occurs 3 months after the 8th session with HIV and STI tests | Behavioral: Risk Reduction<br> <br> |
