国家心理健康研究所多地点艾滋病预防试验是一项干预试验，旨在减少性艾滋病风险行为，在美国7个研究地点的3706名低收入高危男性和女性中进行。基于社会认知理论的干预，旨在通过提高安全套使用的预期结果，增加知识、技能和自我效能来实施更安全的性行为，从而影响行为改变，相对于控制条件，在减少性风险行为方面是有效的。在干预完成3个月后，干预组中这些潜在介质的测量值高于对照组。虽然在对变量进行统计控制后，干预对性危险行为的影响显著降低，支持其中介干预效果的假设，但大部分效果仍然无法解释，表明未测量因素对结果的影响。
The National Institute of Mental Health Multisite HIV Prevention Trial was a trial of an intervention to reduce sexual HIV risk behaviors among 3,706 low-income at-risk men and women at 7 U.S. research sites. The intervention, based on social-cognitive theory and designed to influence behavior change by improving expected outcomes of condom use and increasing knowledge, skills, and self-efficacy to execute safer sex behaviors, was effective relative to a control condition in reducing sexual risk behavior. At 3 months after completion of the intervention, measures of these potential mediators were higher in the intervention than in the control condition. Although the effect of the intervention on sexual risk behavior was significantly reduced when the variables were controlled statistically, supporting the hypothesis of their mediation of the intervention effect, most of the effect remained unexplained, indicating the influence of unmeasured factors on outcome.
