Sounds like a good project.

My Dad's a shrink.  I've taken MANY psych tests thru the years, from him 
and in job interviews etc.  I always played a game: I looked for them to 
use the same question several times, but phrased differently to try and 
check your honesty.  I'm sure your math routines do regression testing 
and ferret out things like that.

Here in the US, Janus Assoc. is a big industrial psych testing company. 
Ever heard of them?  I took their tests when applying for work at Delta 
Airlines.

Who did the db behind your system?

In the past, I designed a 45-table survey system (plus created all the 
front-end) for a client who used it to do post-opening franchise visits, 
interface it back to their guest satisfaction and revenue mgmt systems, etc.

It had a master list of questions from which you could pick to combine 
create new surveys, use different answer scales, question categories, 
screen and report ordering, etc.  Similar to your survey system I would 
guess.
