The Science Behind the Package
The Self-Help in Eliminating Life-threatening Diseases (SHIELD) intervention is an innovative approach to HIV prevention. SHIELD, a group level intervention, trains current and former drug users to be Peer Educators who share HIV prevention information with people in their social networks (e.g., friends, family, sex partners, etc.).

The SHIELD intervention is based on several theories; Social Cognitive Theory, Social Identity Theory, Cognitive Dissonance (or inconsistency) Theory, and Social Influence Theory. In the SHIELD model of HIV prevention, one individual (a Peer Educator) is taught strategies to reduce HIV risk associated with drug use and sex behavior. In addition, Peer Educators are taught effective communication skills in order to talk with people in their social networks about HIV prevention information. Peer Educators are trained to be leaders within their social networks and communities. They use their communication skills to have conversations about prevention to help stop the spread of HIV.

Training current and former drug users, who interact with other drug-using individuals, as Peer Educators is an efficient HIV prevention approach. Peer Educators are more likely to have access to drug users in the community, especially those who may not access traditional prevention services. Furthermore, by training drug users to be Peer Educators, they become an active participant in the community effort to stop the spread of HIV. According to this model, training one individual leads to teaching and positively influencing many others.

SHIELD is low-cost and requires few technology resources and nominal space, which allows for implementation with minimal budget, staff, and facility size. Finally, by training former and current drug users to conduct outreach, hidden and hard-to-reach individuals may be engaged in HIV prevention.

Target Population
The target population for the SHIELD intervention is male and female adults (18 years or older) who are current or former ‘hard’ drug users (heroin, cocaine, and crack) who interact with other drug users. The intervention can be delivered with clients who are HIV positive and HIV-negative.

Intervention
The SHIELD intervention is delivered through 6 small group sessions which can be held in a community-based setting (e.g., community center, health clinic). Each group is led by 2 trained facilitators. Information, referrals, and risk reduction materials are delivered through group problem-solving activities, role-plays, and demonstrations.

SHIELD Session Topics

1. Introduction to the Peer Educator role & Peer Outreach 4. Sexual risk behavior- Part 2
2. PEER Communication skills 5. Injection drug use behavior
3. Sexual risk behavior-Part 1 6. Graduation

Research Results
The SHIELD intervention produced the following results among current and former drug users:

• Increased condom use during vaginal sex with casual sex partners (16% of Peer Educators vs. 4% of control group);
• Increased condom use during oral sex with casual sex partners (12% of Peer Educators vs. 3% of control group);
• Reduced needle sharing (69% of Peer Educators vs. 30% of control group);
• Decreased injection drug use frequency (48% of Peer Educators vs. 25% of control group); and
• Stopped using injection drugs (44% of Peer Educators vs. 22% of control group)

The Intervention

A Package Developed from Science
Replicating Effective Programs (REP) is a CDC-initiated project that supports the translation of evidence-based HIV/AIDS prevention interventions into everyday practice, by working with the original researchers in developing a user-friendly package of materials designed for prevention providers. SHIELD is one of the REP interventions and is the product of extensive collaboration among researchers, a community advisory board, and other community agencies. The package has been field tested in several community agencies and clinics across the United States by non-research staff.

Core Elements

1. SHIELD is implemented in a small group setting (4-12 participants) to offer an environment that is conducive to sharing experiences and gaining social support from peers.
2. Participants go through the specified SHIELD Sequence- a series of activities that includes pre-program contact and 6 sequential intervention sessions.
3. Each SHIELD intervention session follows a specific structure that includes 5 components: Homework check-in, Presentation of new information, Peer Educator training activities, Homework assignment, and Summary.
4. SHIELD sessions aim to build three sets of skills necessary for participants to be a Peer Educator. These skills are:
   
   • Communication skills for conducting effective peer outreach (PEER)
   • HIV injection-related risk reduction techniques
   • HIV sex-related risk reduction techniques
5. Every session includes interactive Peer Educator training activities which build Peer Outreach skills and increase Peer Educator self-efficacy. Through increased self-efficacy, participants develop a Peer Educator Identity. Activities include:
   • Facilitator Role-models, Group Problem-solving activities, & Role-plays
