Nuevo Amanecer: Results of a Randomized Controlled Trial of a Community-Based, Peer-Delivered Stress Management Intervention to Improve Quality of Life in Latinas With Breast Cancer



We evaluated a community-based, translational stress management program to improve health-related quality of life in Spanish-speaking Latinas with breast cancer.


We adapted a cognitive–behavioral stress management program integrating evidence-based and community best practices to address the needs of Latinas with breast cancer. Spanish-speaking Latinas with breast cancer were randomly assigned to an intervention or usual-care control group. Trained peers delivered the 8-week intervention between February 2011 and February 2014. Primary outcomes were breast cancer–specific quality of life and distress, and general symptoms of distress.


Of 151 participants, 95% were retained at 6 months (between May 2011 and May 2014). Improvements in quality of life from baseline to 6 months were greater for the intervention than the control group on physical well-being, emotional well-being, breast cancer concerns, and overall quality of life. Decreases from baseline to 6 months were greater for the intervention group on depression and somatization.


Results suggest that translation of evidence-based programs can reduce psychosocial health disparities in Latinas with breast cancer. Integration of this program into community-based organizations enhances its dissemination potential.
