Even in the presence of promising biomedical treatment as prevention, HIV incidence among men who have sex with men has not always decreased. Counseling interventions, therefore, continue to play an important role in reducing HIV sexual transmission behaviors among gay and bisexual men and other men who have sex with men. The present study evaluated effects of a small-group counseling intervention on psychosocial outcomes and HIV sexual risk behavior.
HIV-positive (HIV+) peer counselors administered seven 2-hour counseling sessions to groups of 5 to 8 HIV+ gay and bisexual men. The intervention employed information provision, motivational interviewing, and behavioral skills building to reduce sexual transmission risk behaviors.
There was a significant reduction in condomless anal sex (CAS) with HIV-negative and unknown HIV-status partners, from 50.0% at baseline to 28.9% of the sample at 3-month follow-up. Findings were robust even when controlling for whether the participant had an undetectable viral load at baseline. Significant reductions were also found in the two secondary psychosocial outcomes, loneliness and sexual compulsivity.
The findings provide preliminary evidence that this intervention may offer an efficient way of concurrently reducing CAS and mental health problems, such as sexual compulsivity and loneliness, for HIV+ gay and bisexual men.

即便存在有前景的生物医学预防疗法，男男性行为者中的艾滋病毒感染率并非总是下降。因此，咨询干预措施在减少男同性恋者、双性恋男性及其他男男性行为者的艾滋病毒性传播行为方面仍发挥着重要作用。本研究评估了小组咨询干预对心理社会结果及艾滋病毒性风险行为的影响。
艾滋病毒呈阳性（HIV+）的同伴咨询师对每组5至8名HIV+男同性恋者和双性恋男性进行了七次为时两小时的咨询。该干预采用提供信息、动机性访谈和行为技能培养来降低性传播风险行为。
与艾滋病毒阴性及艾滋病毒感染状况不明的性伴进行无保护肛交（CAS）的情况显著减少，从基线时的50.0%降至3个月随访时样本的28.9%。即便控制参与者在基线时病毒载量是否不可检测，结果依然可靠。在两项次要心理社会结果，即孤独感和性强迫方面也发现有显著降低。
研究结果提供了初步证据，表明该干预措施可能为同时减少HIV+男同性恋者和双性恋男性的无保护肛交及心理健康问题（如性强迫和孤独感）提供一种有效方法。
