psa-index / csv-index

Post by asperlich »

Hello everybody,

my question seems to be a difficult one...

I am working with a formative model and am now in the stage of testing it for expert validity. As supposed by Fassott/Eggert and Krafft/Götz/Liehr-Gobbers (both in Bliemel et al. , Handbuch pLS-Pfadmodellierung, 2005), I calculated the so-called psa and csv for each indicator. psa is a measure for the unambigousness of the assignment of the indicators to the constructs. Csv measures the content relevance.

It is possible that Anderson/Gerbing (1991) explain the abbreviations in their article but I don't have that at hand right now and won't be able to get it until next week. And there is a chance it does not explain the abbreviations anyway...

So: Does anybody know what these abbreviations stand for? Any educated guess is welcome!

Thank you very much in advance!

Hello,

I found out the answers myself. Just in case anyone is interested:

- psa = proportion of substantive agreement
- csv = substantive validity coefficient

Thank you anyway!
