Abstract A043: Baseline characteristics of rural Spanish-speaking Latina breast cancer survivors enrolled in a community-based RCT of a peer-delivered cognitive-behavioral stress management intervention: The Nuevo Amanecer rural trial

Abstract

Abstract Introduction: Effective interventions tailored for rural Spanish-speaking Latina breast cancer survivors are needed to address their psychosocial health disparities. Purpose: Describe development of a rural community-based cognitive-behavioral stress management program, Nuevo Amanecer-R (NA-R) (New Dawn-R) and baseline characteristics of rural Latina breast cancer survivors enrolled in the RCT testing the program. Methods: Using community-based participatory research (CBPR) strategies, we applied a translational model appropriate for underserved populations that integrated an evidence-based intervention, a community best-practices program, and formative research to develop a program that could be delivered by trained breast cancer survivors (peers) in rural settings. We trained community recruiters to enroll, and collect hair and saliva biospecimens from, Spanish-speaking Latinas with nonmetastatic breast cancer in 3 rural California communities. Women were randomized to receive the program immediately or in 6 months. Primary outcomes include the Functional Assessment of Cancer Therapy-Breast Quality of Life (FACT-B) Total Score and its Physical, Social, Emotional, Functional Well-being, and Additional Concerns about Breast Cancer subscale scores (higher scores=better quality of life), with assessments at baseline, 3 months, and 6 months. Results: Based on input from survivors, advocates, and clinicians, modifications to the initial program for rural Latina survivors included further simplification of language, more visuals, developing stress management videos in Spanish and English, and expansion from 8 to 10 sessions to increase skills practice and healthy lifestyles information. Trained peers are delivering the 10-week NA-R program through weekly in-person 90-minute sessions in participants' homes. Components include managing the initial impact of cancer, finding cancer information and support, thoughts and mood management skills, behavioral stress management skills, and goal-setting. Of 231 women approached, 54 (24%) refused, 24 (10%) were ineligible, and 153 (66%) were randomized (76 to intervention, 77 to control group). To date, all baseline, 90% of 3-month, and 92% of 6-month assessments are completed. Participant characteristics are: mean age of 54.8 years (range, 28 to 88); 69% have < high school education; 66% are married; 80% have public/no health insurance; and 48% experienced financial hardship in the past year. Baseline FACT-B mean scores are: Total Score, 96.7 (possible range 0-144); Emotional Well-being, 17.3 (possible range 0-24); Functional Well-being, 18.2 (possible range 0-28); Social/Family Well-being, 18.2 (possible range 0-28); Physical Well-being, 20.4 (possible range 0-28); and Breast Cancer Concerns, 22.7 (possible range 0-36). Conclusions: Using CBPR principles in the design and implementation of community-based RCTs enhances cultural appropriateness, congruence with community contexts, and recruitment and retention.
