This proposed study is possible because of the convergence of six lines of inquiry: 1) outcome studies that have demonstrated the influence of chronic disease self-management in improving the health status of both English- and Spanish-speaking patients, 2) outcome studies which have demonstrated the effectiveness of an automated telephone intervention in improving the health status of Latinos with diabetes, 3) a pilot study of a diabetes self-management program for Latinos, 4) methodological studies which have established effective means for recruiting and collecting data from Spanish-speaking people with chronic conditions, 5) the availability of valid self-administered instruments, which have been translated into Spanish and validated with Spanish-speaking individuals throughout the United States and abroad; and 6) theoretical studies that identify mechanisms by which self-management interventions affect health status.
