To understand the black box, this paper provides a conceptual framework around which a research protocol is built.
PART I: Begins by reviewing definitions of health, paying close attention to the concept that health is a dynamic state with multiple determinants.
PART II: Creates a Health Status model of health where the production of health/illness is considered to be based on simplified health inputs giving rise to a resulting health output.
PART III: Explores a method of examining the mechanism through which health interventions produce health outcomes.
PART IV: Takes the reader through an exercise that defines the mechanism through which health interventions produce health outcomes.
PART V: Proposes a research protocol for understanding the mechanism by which health interventions produce health outcomes.
