Six months after baseline survey (N(bl) = 522), 91.6\% of PHAs and 56.6\% of community drug users adopted the RAP innovation of giving peer intervention, and 59.5\% of all participants (N(6m) = 367) were exposed to RAP innovation. Sociometric network analysis shows that adoption of and exposure to RAP innovation was associated with proximity to a PHA or a highly active interventionist (HAI), being directly linked to multiple PHAs/HAIs, and being located in a network sector where multiple PHAs/HAIs were clustered. RAP innovation has diffused into the Hartford drug-using community.}, keywords = {Diffusion of Innovation, Drug Users, Health Promotion, Humans, Patient Advocacy, Peer Group, Risk Reduction Behavior, Social Support, Substance-Related Disorders}, issn = {1532-2491}, doi = {10.3109/10826084.2012.644097}, author = {Li, Jianghong and Weeks, Margaret R and Borgatti, Stephen P and Clair, Scott and Dickson-Gomez, Julia} }
