Behavioral Health Theories, Equity, and Disparities in Global Health: A Basic Process Model

Lack of participation in health promoting behaviors and participation in behaviors that contribute to health risks have been linked to health disparities observed among individuals from disadvantaged backgrounds. This chapter presents a basic process model to summarize the effects of socio-structural variables linked to health disparities – socio-economic status, education, health literacy, ethnicity, and religiosity – on individuals’ beliefs and cognitions that determine behavior. Socio-structural characteristics were proposed to have a pervasive effect on individuals’ beliefs and other constructs from social cognition theories which impact their decisions to participate in prospective health behaviors and influence their health outcomes. The model provides a mechanistic explanation for health disparities among individuals from disadvantaged groups. A series of illustrative examples are presented of the application of the proposed model as a means to explain how characteristics linked to disadvantage relate to participation in health behaviors and outcomes via potentially modifiable mediating beliefs and social cognition constructs. Efforts to develop interventions targeting these modifiable beliefs will contribute to the enhancement of long-term global health and illness prevention.
