Know any good online resources about Structural Equation Modelling (with AMOS)?

For one of the studies I’m currently running as part of my PhD, it looks as though structural equation modelling might be an appropriate and useful statistical tool to use for the analysis. My supervisor has recommended that I read up on SEM, but I’ve never used this technique before and only understand the basics (i.e., basic reading on SEM and attending a fairly short advanced stats lecture!).

I’ve been given a helpful book by a colleague, but it’s very detailed and I’m finding it quite challenging to understand, particularly as I think I have a fairly limited knowledge of the mathematical background to the techniques I’ve been using so far (i.e., I understand what statistical tests do, the basic theory behind them, the assumptions they make and what buttons to press in SPSS, but I really don’t understand the advanced mathematics behind it, beyond things like regression equations etc.!).

Therefore, I wondered if anyone had any helpful recommendations for websites that contained informative but accessible resources for people from a non-maths background interested in learning more about SEM. I’m particularly interested in resources geared towards those doing SEM with AMOS, as that is the software I have in my department.

I know this may be a bit of a niche question (I don’t know how many stats nerds there are on Fluther!), but any recommendations would be tremendously appreciated.
