Hispanics have a disproportionate burden of poorer cancer outcomes. "Promotores" (community health workers) have been shown to be effective in delivering interventions to this population. However, little is known about what aspects of the "promotores" influence the delivery of a cancer education intervention as well what interactions between "promotores" and the population influence the priority population's subsequent intentions to change health behaviors. Thus, this study had two main aims: 1) examine which psychosocial determinants of "promotores" influence the number of Hispanic residents reached by "promotores" in educational interventions; and 2) examine the effects of "promotores'" psychosocial determinants and their relationships with Hispanic "colonia" residents on residents' intentions to change health behaviors after receiving a cancer education intervention delivered by "promotores." Study participants included "promotores" and adult Hispanic "colonia" residents living in unincorporated sub-divisions lacking basic infrastructure and services in four south Texas border counties who participated in a cancer education intervention. "Promotores" attended an eight-hour training on cancer prevention, treatment, and healthy survivorship for breast, cervical, and colorectal cancers. "Promotores" then delivered 1.5-hour cancer education interventions to residents. Analysis was conducted with STATA 12.0, using regression models and multilevel mixed-effects linear regression models to assess associations between dependent and independent variables. For aim one, "promotores'" age and years of experience influenced their delivery of a cervical cancer education intervention to Hispanic "colonia" residents. For aim two, "promotores'" psychosocial determinants were not significant in predicting the residents' behavioral intentions; however, the number of formal trainings received from "promotores" by Hispanic residents', their satisfaction with the promotora-delivered training, and their trust in the "promotores'" messages were significant in predicting the residents' behavioral intentions. These are the first examinations of potential relationships between psychosocial determinants of "promotores" and selected outcomes in a cancer education intervention delivered to Hispanic "colonia" residents. Findings suggest numerous areas for exploration in future studies. [The dissertation citations contained here are published with the permission of ProQuest LLC.
