Exploring the influence and application of Campbellian validitytypology in the theory and practice of outcome evaluation, thisvolume addresses the strengths and weaknesses of this oftencontroversial evaluation method and presents new perspectives forits use.
Editors Huey T. Chen, Stewart I. Donaldson and Melvin M. Markprovide a historical overview of the Campbellian typology adoption, contributions and criticism. Contributing authors proposestrategies in developing a new perspective of validity typology foradvancing validity in program evaluation including
* Enhance External Validity
* Enhance Precision by Reclassifying the Campbellian Typology
* Expand the Scope of the Typology
The volume concludes with William R. Shadish’s spirited rebuttalto earlier chapters. A collaborator with Don Campbell, Shadishprovides a balance to the perspective of the issue with aclarification and defense of Campbell’s work.
This is the 129th volume of the Jossey-Bass quarterly reportseries New Directions for Evaluation, an officialpublication of the American Evaluation Association.

EDITORS’ NOTES 1
Huey T. Chen, Stewart I. Donaldson, Melvin M. Mark
1. Validity Frameworks for Outcome Evaluation 5
Huey T. Chen, Stewart I. Donaldson, Melvin M. Mark
This chapter discusses the concept of validity as it applies to outcome evaluation and the contributions of the Campbellian validity typology, as well as related criticisms, and overviews the issue.
2. What Works for Whom, Where, Why, for What, and When? Using Evaluation Evidence to Take Action in Local Contexts 17
John Gargani, Stewart I. Donaldson
After discussing limits of the Campbellian tradition regarding external validity, this chapter argues that the external validity of an evaluation could be enhanced by better addressing issues about what works for whom, where, why, for what, and when.
3. New (and Old) Directions for Validity Concerning Generalizability 31
Melvin M. Mark
This chapter reviews several alternative framings of generalizability issues and provides potentially fruitful directions for enhancing external validity in outcome evaluation.
4. Criticisms of and an Alternative to the Shadish, Cook, and Campbell Validity Typology 43
Charles S. Reichardt
This chapter presents four criticisms of the Shadish, Cook, and Campbell (2002) typology of validity. An alternative typology is proposed that avoids these criticisms.
5. Reframing Validity in Research and Evaluation: A Multidimensional, Systematic Model of Valid Inference 55
George Julnes
A validity framework is described with three dimensions–representation (construct validity), causal inference (internal and external validity), and valuation.
6. Conflict of Interest and Campbellian Validity 69
Ernest R. House
Problems related to bias due to researchers’ intentional and unintentional manipulation are discussed, as are strategies for dealing with such problems and how they might be incorporated within the Campbellian validity tradition.
7. The Construct(ion) of Validity as Argument 81
Jennifer C. Greene
This chapter presents an interpretive/constructivist perspective on outcome evaluation and on the warrants for our outcome-evaluation conclusions. It underscores the importance of developing warrants through argumentation, in addition to selected empirical evidence.
8. Assessing Program Outcomes From the Bottom-Up Approach: An Innovative Perspective to Outcome Evaluation 93
Huey T. Chen, Paul Garbe
The authors argue that, to be stakeholder responsive, evaluation must apply an integrative validity model and a bottom-up approach to outcome evaluation to address both scientific and practical issues.
9. The Truth About Validity 107
William R. Shadish
This chapter discusses the contribution of the chapters in the issue, including the extent to which they offer something new and provide justified arguments, and considers how discussions of validity might contribute productively to evaluation theory and practice.
