The skin cancer prevention framework: a comprehensive tool for population-level efforts in skin cancer.

The Skin Cancer Prevention Team (SCPT) required a comprehensive approach for guiding its efforts in population-level skin cancer prevention. After identifying and reviewing several models, it concluded that an appropriate population-level model applicable to the Alberta context did not exist. Thus, the SCPT, under the Alberta Health Services - Cancer Prevention Program, developed and evaluated a model for Alberta. Three inclusion criteria for a comprehensive framework were identified: 1) use an ecological approach to population health; 2) function as a dynamic tool for planning, implementing and evaluating population-level efforts; and 3) address weaknesses in existing theory in population health and health promotion. Theoretical constructs were layered together, on the basis of the criteria, to develop an omnibus framework. The resulting Framework represents a layering of several constructs used in popular health promotion and population health theories. It merges principles of the realist approach to scientific enquiry with principles of ecological theory. The Framework outlines a three-step, dynamic process for planning, implementing and evaluating population-level efforts. It also provides insight into the larger, unifying influences for changes in health outcomes and the complex mechanisms of behaviour change processes at the population level.
