1. The Idea of Construct Validity

2. Construct Validity Theory Observation CauseConstructEffectConstruct ProgramObservations What you do What you see What you think cause-effect construct program-outcome relationship Can we generalize to the constructs?

3. The Analogy to Law

4. The truth…

5. The Analogy to Law The truth… the whole truth,

6. The Analogy to Law The truth … the whole truth, and nothing but the truth.

11. What Is the Goal? The construct Other construct: A Other construct: C Other construct: B Other construct: D

12. What Is the Goal? Other construct: A Other construct: C Other construct: B Other construct: D Didn’t measure any of the construct The construct

13. What Is the Goal? Other construct: A Other construct: C Other construct: B Measure part of the construct and part of construct B The construct Other construct: D

14. What Is the Goal? The construct Other construct: A Other construct: C Other construct: B Other construct: D Measure part of the construct and nothing else

15. What Is the Goal? The construct Other construct: A Other construct: C Other construct: B Other construct: D Measure all of the construct and nothing else.

16. The Problem l Concepts are not mutually exclusive. l They exist in a web of overlapping meaning. l To enhance construct validity, you must show where the construct is in its broader network of meaning.

17. Could Show That... The construct Other construct: A Other construct: C Other construct: B Other construct: D The construct is slightly related to the other four.

18. Could Show That... The construct Other construct: A Other construct: C Other construct: B Other construct: D Constructs A and C and constructs B and D are related to each other.

19. Could Show That... The construct Other construct: A Other construct: C Other construct: B Other construct: D Constructs A and C are not related to constructs B and D.

20. Example: You Want to Measure Self - esteem

21. Example: Distinguish From... Self- esteem Self-worth Confidence Self- disclosure Openness

22. To Establish Construct Validity l You have to set the construct within a semantic (meaning) net. l You have to provide evidence that your data support the theoretical structure. (Constructs that should be more related, are; constructs that should be less related, are.) l Supply evidence that you control the operationalization of the construct (that your theory has some correspondence with reality).
