To test a new behavioral intervention for black MSM in reducing sexual risk and increasing social support and intentions to use condoms.
A single-site, unblinded randomized trial in New York City with 3-month follow-up.
Participants (n = 283) reporting at least two sexual partners and unprotected anal intercourse with a man in the past 3 months were enrolled and randomized to a social-cognitive theory-based intervention or control comparison. Men in the intervention group participated in five 2-h group sessions focused on creating a group environment with sexual risk-reduction information and exercises woven into joint meal preparation and sharing activities, while exploring self-efficacy perceptions and outcome expectancies. Intervention (n = 142) and control (n = 141) groups received standard HIV counseling and testing at baseline.
No significant differences were found between study arms at 3 months in number of male partners, number of unprotected anal intercourse partners, proportion reporting unprotected sex, number of acts protected by condoms, self-efficacy, condom attitudes, condom intentions, social isolation and psychological distress. In both arms combined, declines from baseline to 3 months were observed in sexual risk behaviors, social isolation and psychological distress, whereas self-efficacy, condom attitudes and condom intentions improved.
As the HIV epidemic continues to have a dramatic impact on black MSM in the USA, the urgency to design innovative interventions continues.
测试一种新的针对黑人男男性行为者的行为干预措施，以减少性风险，增加社会支持，并提高使用避孕套的意愿。
这是一项在纽约市进行的单站点、非盲随机试验，随访时间为 3 个月。
招募了至少有两名性伴侣且过去 3 个月内与男性发生过无保护肛交的参与者（n = 283），并将他们随机分配到基于社会认知理论的干预组或对照组。干预组的男性参加了五次 2 小时的小组会议，重点是在减少性风险的信息和练习中创建一个小组环境，这些信息和练习被编织到共同的膳食准备和分享活动中，同时探索自我效能感和预期结果。干预组（n = 142）和对照组（n = 141）在基线时都接受了标准的 HIV 咨询和检测。
在 3 个月时，研究组之间在男性性伴侣数量、无保护肛交性伴侣数量、报告无保护性行为的比例、避孕套保护性行为次数、自我效能感、避孕套态度、避孕套意愿、社会隔离和心理困扰方面均无显著差异。在两个组中，从基线到 3 个月，性风险行为、社会隔离和心理困扰都有所下降，而自我效能感、避孕套态度和避孕套意愿则有所提高。
由于艾滋病毒流行继续对美国的黑人男男性行为者产生巨大影响，因此继续需要设计创新的干预措施。
