摘要：We describe the feasibility of a Web-based portal for training peer community health advisors (CHAs). We conducted a community-based implementation trial in African American churches between 2012 and 2014. The Web-based portal allows CHAs to log in and view 13 training videos, preparing them to deliver 3 cancer early detection workshops in their churches. Of 8 churches, 6 completed the training, each certifying 2 CHAs. These CHAs took an average of 26 days to complete the training, requiring little technical assistance. Additional technical assistance was required to implement the workshops. The Web-based system appears to be a feasible method for training lay individuals for the CHA role and has implications for increasing the reach of evidence-based interventions. It has been well documented that many evidence-based health promotion interventions fail to achieve further implementation or use in the communities they are intended to serve. 1 Such interventions, without intentional effort, do not disseminate themselves into practice. 2 Interest in dissemination and implementation research is growing. Consistent with Rabin et al., 3 we use the term dissemination to refer to the active process of spreading evidence-based interventions to a particular audience using planned approaches and the term implementation to refer to the processes of integrating evidence-based interventions within a setting. We use the phrase dissemination and implementation to refer to the broader field in general. Previous dissemination and implementation research has mainly focused on health care settings. More research is needed to identify optimal ways to translate research evidence into practice, including interventions in community settings that use community-based participatory methods. 4 This includes research on successful implementation of interventions serving culturally and ethnically diverse populations. 2 Peer health educators are viewed as a promising strategy to achieve this goal. 5 Volunteer laypeople, such as those used in the community health advisor (CHA) model, have been used worldwide to promote health. 6 This model for community health promotion recognizes that CHAs are cultural insiders and trusted sources of information and can help increase access to health care while naturally building capacity in the community for sustained positive health outcomes. 6–10
