This is from the company I work for:

http://www.act.org/products/workforce-act-workkeys/

It may be relevant and the web page includes lots of information.

Note: This product is not from my department, and therefore I am not in the position to answer questions on it. But, the web page has links to questions/answers and people.

I also suggest some scales designed by Bandura http://stanford.edu/dept/psychology/bandura/
