A network-oriented HIV prevention intervention based on social identity theory and peer outreach was implemented for HIV positive and negative drug users. A community sample of 250 were randomly assigned to an equal-attention control condition or a multisession, small-group experimental condition, which encouraged peer outreach; 94% of participants were African American, and 66% used cocaine or opiates. At follow-up, 92% of participants returned, and experimental compared with control group participants were 3 times more likely to report reduction of injection risk behaviors and 4 times more likely to report increased condom use with casual sex partners. Results suggest that psychosocial intervention emphasizing prosocial roles and social identity, and incorporating peer outreach strategies, can reduce HIV risk in low-income, drug-using communities.
针对HIV阳性和阴性吸毒者实施了一项基于社会认同理论和同伴外展的网络导向型HIV预防干预措施。从社区抽取250名样本，随机分配到同等关注的对照条件组或多阶段、小组实验条件组，后者鼓励同伴外展；94%的参与者是非裔美国人，66%使用可卡因或阿片类药物。随访时，92%的参与者返回，与对照组参与者相比，实验组参与者报告注射风险行为减少的可能性高出3倍，报告与临时性伴侣增加使用避孕套的可能性高出4倍。结果表明，强调亲社会角色和社会认同并纳入同伴外展策略的心理社会干预措施，可以降低低收入吸毒社区的HIV风险。
