The Underlying Theories of Precede-Proceed Model Understanding Causal Assumptions and Intervention Assumptions
Prototype of Causal Models and Intervention Models X ? INPUTS (educational, organizational economic, etc.) OUTPUTS (health, quality of life, develop- ment) Different models interpret the content of “X?” according to different theories (or assumptions) about causation and control. Problem Theory: Causes->->->->->->->Effects
Examples of Causal Theories on Which PRECEDE-PROCEED is Based Psychological theories in which X includes behavior, and its antecedents such as attitudes, beliefs, perceptions, and other cognitive variables Sociological theories in which X includes organizational functioning and interorganizational exchange and coalitions. Economic theories in which X includes consumer behavior and organizational response to consumer demand. Pathophysiological theories in which X includes organisms or environmental exposure processes.
