Background: The 10-week Nuevo Amanecer-II intervention, tested through a randomized controlled trial, reduced anxiety and improved stress management skills among Spanish-speaking Latina breast cancer survivors. This paper describes the implementation and equity evaluation outcomes of the Nuevo Amanecer-II intervention delivered in three California rural communities.
Methods: Using implementation and equity frameworks, concurrent convergent mixed methods were applied to evaluate implementation (feasibility, fidelity, acceptability, adoption, appropriateness, and sustainability) and equity (shared power and capacity building) outcomes. Quantitative data were collected using tracking forms, fidelity rating forms, and program evaluation surveys; qualitative data were collected using semi-structured in-depth interviews. Respondents included community-based organization (CBO) administrators, recruiters, compañeras (interventionists), and program participants.
Results: Of 76 women randomized to the intervention, 65 (86%) completed at least 7 of 10 sessions. Participants' knowledge (85% correct of 7 questions) and skills mastery were high (85% able to correctly perform 14 skills). Mean fidelity ratings across compañeras ranged from 3.8 (modeled skills) to 5.0 (used supportive/caring communication); 1-5 scale. The program was rated as very good/excellent by 90% of participants. Participants and compañeras suggested including family members; compañeras suggested expanding content on managing thoughts and mood and healthy living and having access to participant's survivorship care plan to tailor breast cancer information. CBOs adopted the program because it aligned with their priority populations and mission. Building on CBOs' knowledge, resources, and infrastructure, implementation success was due to shared power, learning, responsibility, and co-ownership, resulting in a co-created tailored program for community and organizational contexts. Building intervention capacity prior to implementation, providing funding, and ongoing technical support to CBOs were vital for fidelity and enhancement of recruiter and compañera professional skills. Two of three CBOs created plans for program sustainability beyond the clinical trial; all administrators discussed the need for new funding sources to sustain the program as delivered.
Conclusions: Building on community assets and using equitable participatory research processes were central to the successful implementation of a peer-delivered psychosocial intervention in three rural communities among Spanish-speaking Latinas with breast cancer.
