The<unk>  is a cost–benefit evaluation framework proposed in 1974 by Lawrence W. Green that can help health program planners, policy makers and other evaluators, analyze situations and design health programs efficiently. It provides a comprehensive structure for assessing health and quality of life needs, and for designing, implementing and evaluating health promotion and other public health programs to meet those needs. One purpose and guiding principle of the<unk>  is to direct initial attention to outcomes, rather than inputs. It guides planners through a process that starts with desired outcomes and then works backwards in the causal chain to identify a mix of strategies for achieving those objectives. A fundamental assumption of the<unk>  is the active participation of its intended audience — that is, that the participants ("consumers") will take an active part in defining their own problems, establishing their goals and developing their solutions. In this framework, health behavior is regarded as being influenced by both individual and environmental factors, and hence has two distinct parts. First is an "educational diagnosis"<unk> <unk> , an acronym for Predisposing, Reinforcing and Enabling Constructs in Educational Diagnosis and Evaluation. Second is an "ecological diagnosis"<unk><unk> , for Policy, Regulatory, and Organizational Constructs in Educational and Environmental Development. The<unk>  is multidimensional and is founded in the social/behavioral sciences, epidemiology, administration, and education. The systematic use of the framework in a series of clinical and field trials confirmed the utility and predictive validity of the<unk>  as a planning tool.
