The programs and services at GMA Interventions are based on the premise that behavior health disparities are created and sustained through the interactions of factors that occur at multiple levels of the ecological system. Consequently, “traditional” interventions that do not recognize this complexity have been found to be insufficient to eliminate disparities. Not only does empirical evidence support the contribution of ecological influences to these disparities, but there is an increasing consensus that interventions aimed only at changing individual health have many limitations that multilevel interventions are designed to address.
