Since its founding in 1978, JSI has been committed to improving population health — the collective health outcomes of a group of individuals. In pursuit of its mission, JSI’s work spans a wide range of health issues across diverse populations. With a focus on health research; policy, environmental and systems change; program evaluation; management consulting; quality assurance and improvement; capacity building; and training, JSI uses an ecological framework to apply practical, technically sound, and innovative solutions to the challenges facing public and private clients.
An ecological model contextualizes individual behavior within social and physical environments, recognizing that sustaining changes in health behaviors require policies, environments, and social systems that address the determinants of health and support positive lifestyle habits.
Our motivation to apply an ecological framework has been prompted by persistent disparities in health status and health outcomes along geographic, socio-economic, and racial/ethnic lines. We work with our clients to develop, implement, and evaluate multi-factoral approaches, including population-focused strategies to address determinants of health and individual-focused behavioral change strategies to improve population health.
