Part Five gives specific examples of how theories can be combined for greater impact. PRECEDE-PROCEED—a well-developed planning model that can be used to integrate and apply diverse theoretical frameworks—is discussed in this section. In Chapter Eighteen, Gielen and associates describe the PRECEDE-PROCEED Model for health promotion planning and present two case studies of theory-driven program planning that used the PRECEDE-PROCEED planning model for a child safety program and a diabetes management program.
