同龄人主导的青少年干预措施可以有效地加速行为改变。力量之源自杀预防计划培训中学的学生同侪变革推动者（同侪领导者），以传递预防信息并开展加强心理健康应对机制的活动。该计划目前有学校工作人员选择同行领导人。本研究探讨了潜在的更有效的程序扩散，如果同行领导人已根据网络知情的选择方法。从20所学校的5，746名学生那里收集了基线评估。其中，429人被成年人选为同龄人领袖，他们在整个学年中提供干预内容。我们创建了理论上的替代同行领导人集的基础上的社会网络的特点：意见领导，中心性指标，和关键球员。因为这些集合是理论上的，我们检查了这些集合与实际成人选择的同伴领导者集合的一致性，并将该度量与干预方式的扩散（即，演讲，媒体，沟通，活动）第一年后。成人选择的同伴领导者集合与其他社会测量学方法选择的理论集合的相似度为13.3%-22.7%。使用友谊网络指标产生的同龄人领导者集，比一般学生群体更白色和年轻的关键球员的方法产生了更具代表性的同龄人领导者集。同龄人中的意见领袖比一般人年龄大，肤色也更白色。选择的同侪领导者与理论领导者重叠程度较高的学校，其介入媒介与同侪沟通的扩散程度较高。在以学校为基础的同伴领导的干预措施中使用网络信息可以帮助创建更系统化的同伴领导者选择过程。为了接触到有风险的学生，可能需要通过海报或视频等方式传递间接信息。一种混合办法，即把知名的、受人尊敬的意见领袖与网络内具有战略地位的关键参与者沿着结合起来，可能为干预措施的传播提供最大的潜力。
Peer-led interventions for adolescents are effective at accelerating behavioral change. The Sources of Strength suicide preventive program trains student peer change agents (peer leaders) in secondary schools to deliver prevention messaging and conduct activities that increase mental health coping mechanisms. The program currently has school staff select peer leaders. This study examined potential for more efficient program diffusion if peer leaders had been chosen under network-informed selection methods. Baseline assessments were collected from 5,746 students at 20 schools. Of these, 429 were selected by adults as peer leaders who delivered intervention content through the school year. We created theoretical alternate peer leader sets based on social network characteristics: opinion leadership, centrality metrics, and key players. Because these sets were theoretical, we examined the concordance of these sets with the actual adult-selected peer leaders sets and correlated this metric with diffusion of intervention modalities (i.e., presentation, media, communication, activity) after the first year. The sets of adult-selected peer leaders were 13.3%—22.7% similar to theoretical sets chosen by other sociometric methods. The use of friendship network metrics produced peer leader sets that were more white and younger than the general student population; the Key Players method produced more representative peer leader sets. Peer opinion leaders were older and more white than the general population. Schools whose selected peer leaders had higher overlap with theoretical ones had greater diffusion of intervention media and peer communication. The use of network information in school-based peer-led interventions can help create more systematized peer leader selection processes. To reach at-risk students, delivery of an indirect message, such as through a poster or video, may be required. A hybrid approach where a combination of visible, respected opinion leaders, along with strategically-placed key players within the network, may provide the greatest potential for intervention diffusion.
