Latinas suffer disproportionately from breast cancer relative to non-Latina Whites (NLWs), including late stage detection. While there have been controversies in breast cancer screening, non-adherence to guideline-concordant screening continues to be a major modifiable determinant of breast cancer outcome disparities. Thus, increasing participation in breast cancer screening among Latinas, especially care that corresponds with clinical and academic guidelines, is a public health priority. Participatory approaches are popular methods to improve screening within this group and have included approaches that 1) deliver education to non-adherent Latinas and 2) train community health advocates (community health workers, breast cancer survivors) to engage in breast health promotion. The second approach (empowerment interventions) concerns training participants to engage in social outreach (e.g., having conversations with family and friends about breast health) and volunteering (e.g., helping in health fairs, engaging in civic campaigns about breast cancer programs). Patient activation and volunteerism literature suggest that empowerment interventions may have 'added value' for participants themselves over delivering education in terms of preventive health psychosocial factors and practices. Relative to education interventions, empowerment interventions may also affect women's networks, as they may be more likely to disseminate evidence-based breast health promotion among their family and friends. To date, little research has compared interventions' effects on individual-level outcomes or used formal social network analysis to examine network effects. The proposed work adds to the literature through empirically comparing two approaches (education versus empowerment) on three sets of outcomes: 1) women's own screening, 2) women's own self-efficacy, norms, support, knowledge; and 3) women's networks (measured by egocentric analysis). I will lead this work and will benefit from the collective expertise and resources of my mentors (Drs. Ferrans, Mermelstein, Geller) and collaborators (Dr. Schneider, The Resurrection Project, Metropolitan Chicago Breast Cancer Task Force, Sinai Urban Health Institute, University of Illinois Cancer Center). Aim 1 intervention development will be accomplished through continuous stakeholder engagement and specifically through meetings and focus groups with a bilingual, bicultural community advisory engagement board (CEAB), UICC radiologists and target participants (non-adherent Latinas). We have already begun this process and are obtaining formative data. After we develop intervention materials, a pilot trial will be conducted with an area-level treatment control group design in Chicago. Participants will be 150 Latinas with no history of health volunteerism, residence in one of two targeted areas, and non-adherence to US Preventive Services Task Force screening guidelines. Aim 1 intervention evaluation will involve an analysis to compare differences in receipt of a medical record-confirmed screening within six months of participating in the study. Aim 2 will be an analysis to compare interventions' effects on self-efficacy, norms, support, knowledge across three time points - pre-intervention, immediately post-intervention, and six months post-intervention. Aim 3 will be a social network analysis, specifically egocentric, to compare interventions' effects on breast health, network size, and network density as well as will number of peers referred to the study.
