1The Underlying Theories of Precede-Proceed Model Understanding Causal Assumptions and Intervention Assumptions
2Prototype of Causal Models and Intervention Models Problem Theory: Causes->->->->->->->EffectsINPUTS(educational,organizationaleconomic, etc.)OUTPUTS(health, qualityof life, develop-ment)X ?Most models for planning contain an implicit or an explicit set of assumptions about causation. Unfortunately, these assumptions are too often implicit, so we are left to guess what factor X involves. Is it just behavior, or is it just environment, or is it some combination of lifestyle, environment and health services...Different models interpret the content of “X?” according to different theories (or assumptions) about causation and control.10
3Examples 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 variablesSociological 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.
