Questionaire Design

I am just finishing of an MSc and for my dissertation have to do a bit of research. Now I have a few research books which I am wading my way through but could use a bit of help.

My project is looking at Maintaining motivation in qualified nurses and the perceived effects of morale on patient care.

I am going to approach it using an action research approach because it is research within my own work area so will be working with the staff to improve morale and motivation.

I want to start with a questionare about what impacts on thier morale, how they motivate themselves to professionally develop and get involved with improving patient care and that kind of stuff.

Now I have never written a questionaire before so I thought I would start with some focus groups to establish common themes of what effects motivation and morale on the ward and from pick out the themes and design the questionaire.

Firstly, comments about my project (please don't be too harsh it is a work in progress) any pitfalls, issues or suggestions

Are there any resources out there that I can use for questionaire design, I have a few articles but if there are any websites or books that you think would be useful I'd be very grateful

Thanks
