Document Summary

Definition construct validity involves generalizing from your program or measures to the concept of your program or measures: i want to make two cases here. First, it"s dumb to limit our scope only to the validity of measures. We really want to talk about the validity of any operationalization. That is, any time you translate a concept or construct into a functioning and operating reality (the operationalization), you need to be concerned about how well you did the translation. This issue is as relevant when we are talking about treatments or programs as it is when we are talking about measures. (in fact, come to think of it, we could also think of sampling in this way. The population of interest in your study is the construct and the sample is your operationalization. If we think of it this way, we are essentially talking about the construct validity of the sampling!
