  • Course Text: Planning, Implementing, and Evaluating Health Promotion Programs: A Primer by James F. McKenzie, Brad L. Neiger, and Jan L. Smeltzer


  • Chapter 14, "Evaluation Approaches and Designs"


    This chapter continues the examination of program evaluation. The elements of a good evaluation are presented along with the different procedures that may be used as a part of the evaluation. Different evaluation models are also illustrated along with methods for selecting the appropriate model. Finally, the importance of establishing both internal and external validity and how evaluation design impacts validity is presented.





    • Course Text: Health Program Planning and Evaluation: A Practical, Systematic Approach for Community Health (2nd ed.). by L. Michele Issel




    Chapter 12, "Choosing Designs for Effect Evaluation"


    Chapter 12 takes the typical evaluation design using the traditional experimental, quasi-expeimental or epidemiological approaches to research and then organizes them based on the complexity of the design and the purpose of the evaluation. The decision about the approach to take is dependent on the resources that are available for completing the evaluation and the type of information that is desired. Finally, a detailed description of each of the approaches is presented.
